00:00:00,300 --> 00:00:01,530
Instructor: Welcome back.

2
00:00:01,530 --> 00:00:04,590
Up until now, we've talked about Sublime Text

3
00:00:04,590 --> 00:00:06,540
and Visual Studio Code.

4
00:00:06,540 --> 00:00:10,650
Code editors that we had to install a bunch of plugins

5
00:00:10,650 --> 00:00:14,820
and extensions in order to customize it to what we want.

6
00:00:14,820 --> 00:00:16,590
And they work really well

7
00:00:16,590 --> 00:00:20,220
with a ton of different programming languages.

8
00:00:20,220 --> 00:00:23,220
The next one though is an IDE,

9
00:00:23,220 --> 00:00:24,810
and it's called PyCharm.

10
00:00:24,810 --> 00:00:27,780
And it's probably the most popular tool

11
00:00:27,780 --> 00:00:32,130
for Python developers, so I really, really like it.

12
00:00:32,130 --> 00:00:33,900
But it's an IDE.

13
00:00:33,900 --> 00:00:35,940
That is, unlike a code editor,

14
00:00:35,940 --> 00:00:40,290
it already comes pre-built with a lot of things.

15
00:00:40,290 --> 00:00:42,810
This company, JetBrains, makes it,

16
00:00:42,810 --> 00:00:46,020
and they focus purely on Python developers.

17
00:00:46,020 --> 00:00:48,870
So that is, if you're a Python developer,

18
00:00:48,870 --> 00:00:51,360
they really focus and make sure

19
00:00:51,360 --> 00:00:54,393
that all the tools you need to succeed are in here.

20
00:00:55,590 --> 00:00:58,950
Now, when you click on Download Now,

21
00:00:58,950 --> 00:01:01,320
you have two versions.

22
00:01:01,320 --> 00:01:04,110
The Professional one which you have to pay for,

23
00:01:04,110 --> 00:01:05,760
and the Community one.

24
00:01:05,760 --> 00:01:07,650
So just download the Community one,

25
00:01:07,650 --> 00:01:11,100
the Professional one just comes with a few extra features

26
00:01:11,100 --> 00:01:12,570
that we don't really need.

27
00:01:12,570 --> 00:01:15,000
So download the Community one.

28
00:01:15,000 --> 00:01:19,920
Just a heads-up, it's a lot bigger, it's 315 megabytes.

29
00:01:19,920 --> 00:01:23,340
So, again, it comes with a lot more tools for us to use,

30
00:01:23,340 --> 00:01:25,470
so it is a little bit heavier

31
00:01:25,470 --> 00:01:28,740
than Visual Studio Code or Sublime Text.

32
00:01:28,740 --> 00:01:30,780
But if you're a Python developer

33
00:01:30,780 --> 00:01:32,910
and you just want an environment

34
00:01:32,910 --> 00:01:35,250
where you can do everything in one place,

35
00:01:35,250 --> 00:01:37,740
PyCharm is the way to go.

36
00:01:37,740 --> 00:01:39,510
Now, let's fast forward through this

37
00:01:39,510 --> 00:01:42,240
so that we're not waiting around for the download.

38
00:01:42,240 --> 00:01:43,590
Whew! All right.

39
00:01:43,590 --> 00:01:44,790
That was a long pause for me,

40
00:01:44,790 --> 00:01:46,830
but for you, with some editing,

41
00:01:46,830 --> 00:01:48,120
this should have been quick.

42
00:01:48,120 --> 00:01:48,953
All right.

43
00:01:48,953 --> 00:01:50,910
If I open this up now,

44
00:01:50,910 --> 00:01:54,180
again, if you're on Windows or if you're on Mac,

45
00:01:54,180 --> 00:01:56,850
installation process will be different.

46
00:01:56,850 --> 00:01:59,460
In our case, because we are on a Mac,

47
00:01:59,460 --> 00:02:01,470
I just drag this to Application.

48
00:02:01,470 --> 00:02:04,923
With Windows, you'll probably go through an Installer.

49
00:02:06,090 --> 00:02:07,920
All right, it's all installed.

50
00:02:07,920 --> 00:02:10,020
Now if I double-click,

51
00:02:10,020 --> 00:02:12,993
PyCharm is going to open up for me.

52
00:02:14,430 --> 00:02:16,893
And we'll just make sure we allow it.

53
00:02:18,810 --> 00:02:20,910
Now, in my case,

54
00:02:20,910 --> 00:02:25,110
I had, already, a previous version of PyCharm

55
00:02:25,110 --> 00:02:26,670
that I've been using,

56
00:02:26,670 --> 00:02:29,760
and you might want to import your previous setting.

57
00:02:29,760 --> 00:02:32,610
But, in our case, we've never used PyCharm before,

58
00:02:32,610 --> 00:02:35,670
and also most likely you want a fresh install.

59
00:02:35,670 --> 00:02:38,370
So even if you get this type of pop-up,

60
00:02:38,370 --> 00:02:40,560
you can just click on Do not import settings

61
00:02:40,560 --> 00:02:42,213
so you get a fresh slate.

62
00:02:43,230 --> 00:02:44,970
We're going to click OK.

63
00:02:44,970 --> 00:02:47,220
And there we have it.

64
00:02:47,220 --> 00:02:50,100
And right away, you can see that,

65
00:02:50,100 --> 00:02:52,470
well, it gives us a lot of options.

66
00:02:52,470 --> 00:02:54,510
Let's just say I've never used PyCharm before.

67
00:02:54,510 --> 00:02:57,030
And next, we get to choose our UI.

68
00:02:57,030 --> 00:03:00,750
Do we want Darcula which is dark, or do we want Light?

69
00:03:00,750 --> 00:03:02,223
Let's go with dark for now.

70
00:03:05,040 --> 00:03:08,373
So I'm going to skip the remaining and set defaults.

71
00:03:12,960 --> 00:03:17,960
So in PyCharm now, we can create a new project.

72
00:03:18,420 --> 00:03:22,050
Now in here, it asks us where we wanna create our project.

73
00:03:22,050 --> 00:03:24,420
In my case, we can just leave it over here.

74
00:03:24,420 --> 00:03:26,187
We'll call it myproject.

75
00:03:27,930 --> 00:03:30,570
And before we click Create,

76
00:03:30,570 --> 00:03:33,880
make sure that you click on this Project Interpreter

77
00:03:35,490 --> 00:03:39,930
and double-check that our base interpreter

78
00:03:39,930 --> 00:03:42,480
is using Python 3.

79
00:03:42,480 --> 00:03:44,370
Remember, if you're on a Mac or Linux,

80
00:03:44,370 --> 00:03:48,060
you might have Python 2 already installed.

81
00:03:48,060 --> 00:03:52,890
In our case, we installed our Python version 3.7 right here.

82
00:03:52,890 --> 00:03:56,460
So we make sure that this latest version of Python

83
00:03:56,460 --> 00:03:58,923
is what's being used as the interpreter.

84
00:03:59,880 --> 00:04:01,773
Now we can just click Create,

85
00:04:02,880 --> 00:04:05,253
and our project is going to start for us.

86
00:04:08,730 --> 00:04:09,990
We can close these tips,

87
00:04:09,990 --> 00:04:12,480
every once in a while you get Tip of the Day.

88
00:04:12,480 --> 00:04:14,370
Because this is an IDE,

89
00:04:14,370 --> 00:04:19,370
you get a lot of features that you can read about online.

90
00:04:19,589 --> 00:04:23,460
So it might take you a while to get used to PyCharm,

91
00:04:23,460 --> 00:04:25,233
but it is a very powerful tool.

92
00:04:27,210 --> 00:04:29,280
Let's make this a little bit bigger.

93
00:04:29,280 --> 00:04:33,090
Now with myproject here, I can right click,

94
00:04:33,090 --> 00:04:35,973
say New, and then select File.

95
00:04:37,020 --> 00:04:41,283
Our file, we'll just call it hihi.py.

96
00:04:42,270 --> 00:04:43,143
Click OK.

97
00:04:44,640 --> 00:04:45,510
And there we go.

98
00:04:45,510 --> 00:04:48,360
We have our first file opened up,

99
00:04:48,360 --> 00:04:51,870
and we can just, once again, say print.

100
00:04:51,870 --> 00:04:54,330
Now, this is definitely way too small,

101
00:04:54,330 --> 00:04:57,450
so I'm going to go to PyCharm, Preferences,

102
00:04:57,450 --> 00:04:59,520
and here it gives you a ton of options

103
00:04:59,520 --> 00:05:02,490
to customize PyCharm to your liking.

104
00:05:02,490 --> 00:05:05,460
In my case, I wanna make sure that I use,

105
00:05:05,460 --> 00:05:06,960
let's say, custom font,

106
00:05:06,960 --> 00:05:08,940
but definitely increase the size to...

107
00:05:08,940 --> 00:05:10,170
Let's go with 18.

108
00:05:10,170 --> 00:05:11,003
How's that?

109
00:05:11,003 --> 00:05:11,836
Let's apply.

110
00:05:12,840 --> 00:05:13,673
That's better.

111
00:05:13,673 --> 00:05:15,660
You know what? I want it even bigger.

112
00:05:15,660 --> 00:05:17,460
Let's do 20.

113
00:05:17,460 --> 00:05:18,783
I'm gonna hit OK.

114
00:05:20,730 --> 00:05:23,190
All right, this side is now bigger.

115
00:05:23,190 --> 00:05:24,390
That's great, we can see it.

116
00:05:24,390 --> 00:05:27,480
But, hmm, this is still tiny,

117
00:05:27,480 --> 00:05:28,680
I want this a little bit bigger,

118
00:05:28,680 --> 00:05:30,480
so let's fix that as well.

119
00:05:30,480 --> 00:05:33,540
We can fix this easily by pressing Command

120
00:05:33,540 --> 00:05:37,320
and then using the mouse wheel if you have a mouse,

121
00:05:37,320 --> 00:05:42,320
or using two fingers and zooming in like so.

122
00:05:42,810 --> 00:05:44,820
If you're on a Windows machine,

123
00:05:44,820 --> 00:05:47,130
it'll be Control instead of Command,

124
00:05:47,130 --> 00:05:50,463
and just zooming in and out as you like.

125
00:05:51,330 --> 00:05:54,120
Now, the interesting thing here with PyCharm,

126
00:05:54,120 --> 00:05:56,100
I know we have a ton of things

127
00:05:56,100 --> 00:05:59,280
that we might not be familiar with right now,

128
00:05:59,280 --> 00:06:04,280
but the key thing is that Python 3.7 is running our project.

129
00:06:04,530 --> 00:06:08,763
And if we type something like print, heyhey,

130
00:06:10,200 --> 00:06:13,170
we get a ton of interesting things.

131
00:06:13,170 --> 00:06:17,197
First, we get a typo saying,

132
00:06:17,197 --> 00:06:21,390
"Hey, this whole heyhey is not an English word."

133
00:06:21,390 --> 00:06:23,430
If I add spaces, look at that.

134
00:06:23,430 --> 00:06:26,520
It even gives me typos of English words.

135
00:06:26,520 --> 00:06:30,150
But then I also have this yellow curly bracket,

136
00:06:30,150 --> 00:06:34,080
or squiggly line, and it tells me "PEP eight,

137
00:06:34,080 --> 00:06:36,270
no newline at the end of the file."

138
00:06:36,270 --> 00:06:38,520
This is something that we're gonna talk about shortly

139
00:06:38,520 --> 00:06:41,310
when we talk about formatting our code.

140
00:06:41,310 --> 00:06:43,200
But if I add a new line,

141
00:06:43,200 --> 00:06:46,020
look at that, everything is working smoothly,

142
00:06:46,020 --> 00:06:48,330
I get a nice little check mark.

143
00:06:48,330 --> 00:06:50,080
Now I can run this code

144
00:06:51,240 --> 00:06:55,290
by going to Run, and then clicking Run,

145
00:06:55,290 --> 00:06:58,380
and you can see the shortcut command here as well.

146
00:06:58,380 --> 00:07:00,487
If I Run this, it asks me,

147
00:07:00,487 --> 00:07:01,680
"Hey, what do you wanna Run?"

148
00:07:01,680 --> 00:07:05,160
Well, I wanna Run the new hihi Python file.

149
00:07:05,160 --> 00:07:06,360
I click on this.

150
00:07:06,360 --> 00:07:08,010
And look at that.

151
00:07:08,010 --> 00:07:09,870
Let's make this a little bit bigger.

152
00:07:09,870 --> 00:07:10,703
That's better.

153
00:07:12,240 --> 00:07:15,180
We see that our file is being run,

154
00:07:15,180 --> 00:07:17,370
the process finished with the exit code zero.

155
00:07:17,370 --> 00:07:18,360
Zero is a good sign.

156
00:07:18,360 --> 00:07:21,783
It means there were no errors and everything is great.

157
00:07:22,950 --> 00:07:24,630
Now, if we make an error here

158
00:07:24,630 --> 00:07:27,660
and let's say I miss my brackets and I hit Run,

159
00:07:27,660 --> 00:07:31,500
or I can just click on Run here, look at that.

160
00:07:31,500 --> 00:07:32,707
It gives me an error saying,

161
00:07:32,707 --> 00:07:34,353
"Hey, hey, hey, SyntaxError,

162
00:07:35,220 --> 00:07:37,890
unexpected EOF while parsing."

163
00:07:37,890 --> 00:07:39,750
And tells you something went wrong.

164
00:07:39,750 --> 00:07:42,180
So, once again, I can fix it,

165
00:07:42,180 --> 00:07:45,360
Run my code, and everything is good.

166
00:07:45,360 --> 00:07:46,740
There are a lot of features here

167
00:07:46,740 --> 00:07:50,550
that you can explore on your own, get comfortable with it.

168
00:07:50,550 --> 00:07:53,550
PyCharm is definitely a great IDE.

169
00:07:53,550 --> 00:07:55,950
And the beauty is that unlike Sublime Text

170
00:07:55,950 --> 00:07:59,100
or Visual Studio Code where we had to install

171
00:07:59,100 --> 00:08:00,630
all these packages,

172
00:08:00,630 --> 00:08:05,630
PyCharm comes, well, with everything built-in, it's an IDE.

173
00:08:06,450 --> 00:08:09,330
We don't have to install any of these packages.

174
00:08:09,330 --> 00:08:11,160
This environment is already set up

175
00:08:11,160 --> 00:08:13,770
for us to work professionally with Python

176
00:08:13,770 --> 00:08:17,370
because it is made for Python developers.

177
00:08:17,370 --> 00:08:19,270
I'll see you in the next one, bye-bye.
