Introducing the for Loop. >>> li = [.a.b.e.] >>> for s in li: 1 print s 2 a b e >>> print "\n".join(li) Just iterate through the list, as shown in the previous example. We are going to use a for-loop in this exercise to build and print various lists. When you. Open up the Python shell and try a few examples with a list you make. It has the ability to iterate over the items of any sequence, such as a list or a string usr/bin/python for letter in.Python.: # First Example print.Current Letter:.

And:After each iteration, the variable i has 2 added to it. shows while-loop i = 0 # While loop condition. while i < 10: print(i) # Add two. i += 2 Output 0 2 4 6 8. For w in words[:]: # Loop over a slice copy of the entire list. if len(w) > 6: loop fell through without finding a factor print n,.is a prime number. The continue statement, also borrowed from C, continues with the next iteration of the loop.

The for loop in Python is used to iterate over a sequence (list, tuple, string) or other sum sum = 0 # iterate over the list for val in numbers: sum = sum+val # print.
