New submission from Mitchell Model <m...@acm.org>:
Near the bottom of the library documentation for pdb there is an example
of a very useful alias:
alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k])
It turns out that doing print in a for loop in pdb results in None being
printed on a line after each print. For example:
(Pdb)
for n in range(3): print(n)
0
None
1
None
2
None
(Pdb)
Seems like a (minor) bug, but if not, the example should be removed or
replaced in the documentation.
