Function touch

pex/common.py:640–653

Equivalent of unix `touch path`. If no times is passed, the current time is used to set atime and mtime. If a single int or float is passed for times, it is used for both atime and mtime. If a 2-tuple of ints or floats is passed, the 1st slot is the atime and the 2nd the mtime, just as

(
    file,  # type: _Text
    times=None,  # type: Optional[Union[int, float, Tuple[int, int], Tuple[float, float]]]
)

def touch(
    file,  # type: _Text
    times=None,  # type: Optional[Union[int, float, Tuple[int, int], Tuple[float, float]]]
):
    # type: (...) -> _Text
