python cast to int

1# Use the function int() to turn a string into an integer
2string = '123'
3integer = int(string)
4integer
5# Output:
6# 123

1# convert float to int 
2x=3.1415
3y=int(x)
4print(y) #outputs 3

1# this is a string
2a = "12345"
3# use int() to convert to integer
4b = int(a)
5
6# if string cannot be converted to integer,
7a = "This cannot be converted to an integer"
8b = int(a)  # the interpreter raises ValueError

1>>> str(123)
2'123'
3

1float('1.234')

1x = int(1)   # x will be 1
2y = int(2.8) # y will be 2
3z = int("3") # z will be 3
