In a Python
for loop that iterates over a list we can write:
for item in list: print item
and it neatly goes through all the elements in the list. Is there a way to know within the loop how many times I've been looping so far? For instance, I want to take a list and after I've processed ten elements I want to do something with them.
The alternatives I thought about would be something like:
count=0 for item in list: print item count +=1 if count % 10 == 0: print 'did ten'
for count in range(0,len(list)): print list[count] if count % 10 == 0: print 'did ten'
Is there a better way (just like the
for item in list) to get the number of iterations so far?
Agree with Nick. Here is more elaborated code.
#count=0 for idx, item in enumerate(list): print item #count +=1 #if count % 10 == 0: if (idx+1) % 10 == 0: print 'did ten'
I have commented out the count variable in your code.
