In Python there are two kind of numbers. One is integer and the other is float. We have in built methods in Python that can change an integer to float and change float to integer.

I hope you will understand the code below. The output is self explanatory. Read the comment also.


#!/usr/bin/python3
def main():
    x = 3
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    x = 3 /2
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    x = round(42 / 9)
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    # we want to round it up
    x = 42 // 9
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    # how many digits we want to round to
    x = round(42 / 9, 3)
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    x = 43 % 7
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    x = int(34.78)
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
    x = float(23)
    print(x)
    print(id(x))
    print(type(x))
    print("*********")
if __name__ == "__main__":
    main()
