Can I import Python's 3.6's formatted string literals (f-strings) into older 3.x, 2.x Python?

Question

The new Python 3.6 f-strings seem like a huge jump in string usability to me, and I would love to jump in and adopt them whole heartedly on new projects which might be runni

I've been using 'str'.format(**locals()) for a while but made this after a while because the additional code was a bit cumbersome for each statement

def f(string):
    """
    Poor man's f-string for older python versions
    """
    import inspect

    frame = inspect.currentframe().f_back

    v = dict(**frame.f_globals)
    v.update(**frame.f_locals)

    return string.format(string, **v)

# Example
GLOBAL = 123


def main():
    foo = 'foo'
    bar = 'bar'

    print(f('{foo} != {bar} - global is {GLOBAL}'))


if __name__ == '__main__':
    main()
