- 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.

()- 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

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

Documentation §§§§
- Returns True when the argument is true, False otherwise.
The builtins True and False are the only two instances of the class bool.
The class bool is a subclass of the class int, and cannot be subclassed.

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.

(0, 1)
- Return a pair of integers, whose ratio is equal to the original int.
- bit_count
()- Number of ones in the binary representation of the absolute value of self.
Also known as the population count.
»> bin(13)

- Number of ones in the binary representation of the absolute value of self.
- bit_length
()- Number of bits necessary to represent self in binary.
»> bin(37)
‘0b100101’
»> (37).bit_length()
6
- Number of bits necessary to represent self in binary.
- 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.
- Return the integer represented by the given array of bytes.
- 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.
- Return an array of bytes representing an integer.
