there is no type cast in python, every conversion in python will create a new object. Not like in Java and C++, the original object will still be exist in the system.

there are some of the built in functions in python to help the conversion. Such as:

>>> int('123')

123

>>> int(45.67)

45

>>> round(1.15, 1)

1.2

>>> float(10)

10.0

>>> divmod(15, 6)

(2, 3)

>>> ord('a')

97

>>> chr(65)

'A'

    round(number[, ndigits]) -> number

    

    Round a number to a given precision in decimal digits (default 0 digits).

    This returns an int when called with one argument, otherwise the

    same type as the number. ndigits may be negative.
