Function untokenize

Lib/tokenize.py:326–344

Transform tokens back into Python source code. It returns a bytes object, encoded using the ENCODING token, which is the first token sequence output by tokenize. Each element returned by the iterable must be a token sequence with at least two elements, a token number and token value

    Each element returned by the iterable must be a token sequence

    only two tokens are passed, the resulting output is poor.

    The result is guaranteed to tokenize back to match the input so
    that the conversion is lossless and round-trips are assured.
    The guarantee applies only to the token type and token string as
    the spacing between tokens (column positions) may change.
