"""
|

|
|
The following code is valid in Python 2:
|
||
|
|
|
||
|
|
for x in my_dict.keys():
|
||
|
|
if something(x):
|
||
|
|
del my_dict[x]
|
||
|
|
|
||
|
|
But broken in Python 3.
|
||
|
|
|
||
|
|
One solution is:
|
||
|
|
|
||
|
|
for x in list(my_dict.keys()):
|
||
|
|
if something(x):
|
||
|
|
del my_dict[x]
|
||
|
|
|
||
|
|
Some but not all code in Tahoe has been changed to that. In other cases, the code was left unchanged since there was no `del`.
|
||
|
|
|
||
|
|
However, some mistakes may have slept through.
|
||
|
|
|
||
|
|
To help catch cases that were incorrectly ported, this script runs futurize on all ported modules, which should convert it into the `list()` form.
|
||
|
|
You can then look at git diffs to see if any of the impacted would be buggy without the newly added `list()`.
