• 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.

Runtime functions

• as_integer_ratio()
  • Return a pair of integers, whose ratio is equal to the original int.
    
    The ratio is in lowest terms and has a positive denominator.
    
    »> (10).as_integer_ratio()
    (10, 1)
    »> (-10).as_integer_ratio()
    (-10, 1)
    »> (0).as_integer_ratio()
    (0, 1)
• bit_count()
  • Number of ones in the binary representation of the absolute value of self.
    
    Also known as the population count.
    
    »> bin(13)
    ‘0b1101’
    »> (13).bit_count()
    3
• bit_length()
  • Number of bits necessary to represent self in binary.
    
    »> bin(37)
    ‘0b100101’
    »> (37).bit_length()

• conjugate()
  • Returns self, the complex conjugate of any int.
• from_bytes(bytes, byteorder='big', *, signed=False)
  • 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. Default is to use ‘big’.
    signed
    Indicates whether two’s complement is used to represent the integer.
• is_integer()
  • Returns True. Exists for duck type compatibility with float.is_integer.
• to_bytes(length=1, byteorder='big', *, signed=False)
  • Return an array of bytes representing an integer.
    
    length
    Length of bytes object to use. An OverflowError is raised if the
    integer is not representable with the given number of bytes. Default
    is length 1.
    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. Default is to use ‘big’.
    signed
    Determines whether two’s complement is used to represent the integer.
    If signed is False and a negative integer is given, an OverflowError
    is raised.
