How to modify list while iterating

Question

I want to loop over items so that I can skip an item while looping, and the below shown code does not  give expected output.

l  = range(100)                         
for i in l:                         
    print i,                         
    print l.pop(0),                  
    print l.pop(0)

Hi,

You can try slice operator mylist[::3] to skip across to every third item in your list.

mylist = [i for i in range(100)]
for i in mylist[::3]:
  print(i)
