1 00:00:00,620 --> 00:00:01,500 Welcome back. 2 00:00:01,520 --> 00:00:10,280 Remember in Python that string is written as SDR and this is a special word. 3 00:00:10,310 --> 00:00:14,930 Actually it's a built in what we call a function or a built in action that we can take. 4 00:00:14,960 --> 00:00:26,450 Now let me ask you this what happens if I do string 100 one hundred is clearly a number an integer but 5 00:00:26,780 --> 00:00:36,860 what if we run the string function on this let's find out let's do print here and then run this. 6 00:00:36,860 --> 00:00:41,870 If I click Run I get a hundred. 7 00:00:41,930 --> 00:00:43,230 All right. 8 00:00:43,310 --> 00:00:51,800 But is this an int or a string to find that out. 9 00:00:51,860 --> 00:00:54,970 Once again let's wrap this. 10 00:00:55,190 --> 00:01:04,760 So the answer of whatever this value is into type. 11 00:01:05,000 --> 00:01:10,760 I know this is a lot of brackets but remember we're evaluating this piece of code. 12 00:01:11,120 --> 00:01:16,820 So we're turning 100 into a string or running the string action and then we're going to check the type 13 00:01:16,940 --> 00:01:19,850 of this entire thing and then we're going to print it out. 14 00:01:20,000 --> 00:01:25,130 If I click Run I see that it's a String type. 15 00:01:25,130 --> 00:01:29,580 So we've converted one hundred into string using this. 16 00:01:29,780 --> 00:01:34,430 Now just to confuse you a little bit more what if we do something like 17 00:01:38,630 --> 00:01:40,800 like this all right. 18 00:01:40,830 --> 00:01:41,850 Even more brackets. 19 00:01:41,850 --> 00:01:42,800 What happens now. 20 00:01:42,840 --> 00:01:52,390 Can you guess while we convert a hundred into a string then convert it back into an integer and then 21 00:01:52,390 --> 00:01:54,660 we check the type of it which is a class INT. 22 00:01:54,670 --> 00:01:55,630 And then we print that. 23 00:01:56,380 --> 00:02:07,420 So remember this was the same as me saying A equals SDR one hundred and then B is going to equal int 24 00:02:09,570 --> 00:02:19,230 of A because we're evaluating this part and then I'm saying C is going to equal the type of whatever 25 00:02:19,800 --> 00:02:21,580 B is. 26 00:02:21,670 --> 00:02:31,890 And then finally we're printing C so that piece of code was the same as doing this very very cool. 27 00:02:31,890 --> 00:02:37,300 Now this is the idea of type conversion again. 28 00:02:37,310 --> 00:02:41,630 If I were to write that down it's called type conversion. 29 00:02:41,690 --> 00:02:49,100 We're converting the type of our data types and you can do that throughout programming and we'll talk 30 00:02:49,490 --> 00:02:52,130 a lot about this throughout the course. 31 00:02:52,130 --> 00:02:59,210 But it's the main reason we have things like SDR int we have things like float and many other data types 32 00:02:59,210 --> 00:03:00,700 that we're going to talk about. 33 00:03:00,920 --> 00:03:02,800 I'll see in the next video by.
