Python: ones complement using join and lambda

I am trying to create pipeline that converts a number to its Ones' complement number, for example (8)

1234 -> 7654

83743 -> 05145

I tried to create something in this style but I can't figure out how to build the pipeline correctly.

int(''.join((my_number(lambda y: 8-y, list(my_number)))))

Error

TypeError: 'int' object is not callable

Solution

  • The following should work:

    int(''.join([str(8-int(y)) for y in str(my_number)]))

    Example:

    my_number=1258437620

    Output:

    >>> int(''.join([str(8-int(y)) for y in str(my_number)]))
