- >>>help(int)
- Help on class int in module builtins:
- class int(object)
- | 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 literal.
- | >>> int('0b100', base=0)
- | 4

- | Class methods defined here:
- |
- | from_bytes(bytes, byteorder, *, signed=False) from builtins.type
- | Return the integer represented by the given array of bytes.
- |
- | bytes
- | Holds the array of bytes to convert. The argument must either
- | support the buffer protocol or be an iterable object producing bytes.
- | Bytes and bytearray are examples of built-in objects that support the
- | buffer protocol.
- | byteorder
- | The byte order used to represent the integer. If byteorder is 'big',
- | the most significant byte is at the beginning of the byte array. If
- | byteorder is 'little', the most significant byte is at the end of the
- | byte array. To request the native byte order of the host system, use
- | `sys.byteorder' as the byte order value.
- | signed
- | Indicates whether two's complement is used to represent the integer.
