I am using the following code:
for i, f in filelist, self.checkbox:
if f.get():
print i
I am getting an error:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python23\lib\lib-tk\Tkinter.py", line 1345, in __call__
return self.func(*args)
File "install.py", line 123, in select_stage
for i, f in filelist, self.checkbox:
ValueError: unpack list of wrong size
Both filelist and self.checkbox are the same size (4 items btw). Is
there any way to get this done?
Thanks,
Harlin 4 1119

Use zip:
a, b = [1,2,3], ['a', 'b', 'c']
for i,j in zip(a,b):
print i,j
Or from itertools izip - which should be slightly more performant and less
memory consuming.

If sequences are not same length:
zip truncates to length of shortest input sequence
map(None, seq1, seq2) pads to length of longest seq.
(can't remember what itertools.izip() does)
Actually the sequences are of the same length. Forgot to mention that.
