Python provides functions to explicitly convert numbers from one type to another: float (< number, variable, string > ) int (< number, variable, string > ) str (< number, variable > ) Note: int truncates , meaning it throws away the decimal point and anything that comes after it. If you need to round to the nearest whole number, use:

comma(s). In Python, the int type can be expressed in decimal format (the base is 10), which is the default format. The following prints out a negative integer expressed in the decimal format. >>> print(-25) -25 In Python, an integer can also be expressed in binary (the base is 2), octal (the base is 8), or hexadecimal (the best is 16) formats.
