int
- int(number=0, /)
- int(string, /, base=10)
int([x]) -> integer
int(x, base=10) -> integer
Convert a number or string to an integer, or return 0 if no arguments
are given. If x is a number, return x.__int__(). For floating-point
numbers, this truncates towards zero.
If x is not a number or if base is given, then x must be a string,
bytes, or bytearray instance representing an integer literal in the
given base. The literal can be preceded by '+' or '-' and be surrounded
by whitespace. The base defaults to 10. Valid bases are 0 and 2-36.
Base 0 means to interpret the base from the string as an integer
iteral.
>>> int('0b100', base=0)

Changed in 3.4, 3.6, 3.7, 3.8, 3.11, 3.14
- 3.4: If base is not an instance of int and the base object has a base.__index__ method, that method is called to obtain an integer for the base. Previous versions used base.__int__ instead of base.__index__.
- 3.6: Grouping digits with underscores as in code literals is allowed.
- 3.7: The first parameter is now positional-only.
- 3.8: Falls back to __index__() if __int__() is not defined.
- 3.11: int string inputs and string representations can be limited to help avoid denial of service attacks. A ValueError is raised when the limit is exceeded while converting a string to an int or when converting an int into a string would exceed the limit. See the integer string conversion length limitation documentation.
- 3.14: int() no longer delegates to the __trunc__() method.
