Tools for helping manage xontributions.

exception xonsh.xontribs.XontribNotInstalled[source]#

raised when the requested xontrib is not found

add_note()#

Exception.add_note(note) – add a note to the exception

with_traceback()#

Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.

args#
class xonsh.xontribs.ExitCode(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)[source]#
as_integer_ratio(/)#

Return integer ratio.

Return a pair of integers, whose ratio is exactly equal to the original int and with 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()
6
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.

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.

INIT_FAILED = 2#

denominator#

imag#

the imaginary part of a complex number
