What is a the Python code you requested given the following:
Complete the below
def ambiguous_identifier(logical_line, tokens):

    ''''Never use the characters \'l\', \'O\', or \'I\' as variable names.
    In some fonts, these characters are indistinguishable from the numerals
    one and zero. When tempted to use \'l\', use \'L\' instead.
    Okay: L = 0
    Okay: o = 123
    Okay: i = 42
    E741: l = 0
    E741: O = 123
    E741: I = 42
    Variables can be bound in several other contexts, including class and
    function definitions, \'global\' and \'nonlocal\' statements, exception
    handlers, and \'with\' statements.
    Okay: except AttributeError as o:
    Okay: with lock as L:
    E741: except AttributeError as O:
    E741: with lock as l:
    E741: global I
    E741: nonlocal l
