apply method in pandas.DataFrame has signature like this:
DataFrame.apply(func, axis=0, broadcast=False, raw=False, reduce=None, args=(), **kwds)
If I have a function with parameter, how can I pass this function to apply?
For example, the function is:
def foo(x, activation = 3.0):
...
return calculated_val
When I set args = 5, there is an error says, *args must be an iterable.

1Use `df.apply(foo, args=(5,))` ? – Jon Clements Apr 15 '18 at 07:24
