### variable: container for storing data value
_x = 12      # integer value
print(type(_x))
y = "78746287"   #string value
print(type(y))
print(_x , y)
##casting : convert from variable type two another type
print(type(str(_x)))
print(type(int(y)))

### name of variable
FirstVriable = 10

## assign multi values to variable
x , y, z = 1, 2 ,3
n, m, l = "dfsd", "adas", "sadad"
q=w=e=5
print(q, w,e)
### output variable print()
#c =_x+y
# format string : you can include a number in side text
print("the summation of two variables: {} cm".format(_x +y))

#### variable datatype
x = 12
u = "dfdsfsf"
h = 21.5343
lst = [2, 3,554]
print(lst[2])
n = b'fjhfgjhsd'
print(type(n))
### Python Numbers are 3: int, float, complex
x = 232
v = 4343.656   # double
v1 = 32.434354334534534534

### generate random number
import random
y = int(random.random() * 1000)
print(y)
m = random.randrange(100, 200)
print(m)
