I have been hit by this problem but I anticipate it is going to hit me in the future.
Case1 : I have use phi_func = False in a code (so can I turn on and off easily later)
and then define a variable call phi_func to be assigned any of the 3 predefined functions Sure enough if phi_func: suddenly becomes true. Took me a while to figure out.
Case2: I have accidentally use dict for a dictionary type variable. No problem when the code
is short. But when the code grows big and when i use
ax.text( …, bbox=dict(…)) that gives very strange error about dict is not callable.
For Case2 I spent a few good hours trying to isolate the “bug”.
This name collision is killer. It is a compounded by sophisticated syntax esp in matplotlib.
Live with it as long as we are using python? I believe just too many hours per person have been spent
in this kind of thing.
