I just started with python.. I got an error with for loop.. What is the problem ??
Traceback (most recent call last):
File "userentry.py", line 34, in <module>
userentry(p,i)
File "userentry.py", line 26, in userentry
for cl in len(mylist):
TypeError: 'int' object is not iterable
Please help me
You can just iterate over the list, you don't iterate over the length of the list.
for cl in mylist:
# do stuff
If you need to keep track of the index of the current item, use enumerate:
for idx, item in enumerate(mylist):
# idx = index of current item
# item = current item
When you try to do for cl in len(mylist), that's like saying for cl in 5 (if mylist has length of 5), which doesn't really make sense. If you want to just iterate over the indices of a list, it's best to use the enumerate example above, but you can also do
for i in range(len(mylist)):
# mylist[i] is the ith item in the list
Though there are very few reasons to do this instead of just using the enumerate version above.
you should write
for cl in mylist:
len() is not iterable.
for cl in mylist:
print repr(cl)
#do whatever
