Function tryall

web/utils.py:1201–1242

Tries a series of functions and prints their results. `context` is a dictionary mapping names to values; the value will only be tried if it's callable. >>> tryall(dict(j=lambda: True)) j: True ---------------------------------------- results:

(context, prefix=None)

    For example, you might have a file `test/stuff.py`
    with a series of functions testing various things in it.
    At the bottom, have a line:

        if __name__ == "__main__": tryall(globals())

    Then you can run `python test/stuff.py` and get the results of
    all the tests.
