What is the use of "else" after "for" loop in Python? [duplicate]

Question

It seems both of the below codes are printing the same, then what is the need of "else" block after "for" loop in python.

Code 1:

for i in range(10):
    print i
else:
    print "after for loop"

Code 2:

for i in range(10):
    print i

print "after for loop"

Thanks in advance.

Answer 1

From the documentation:

Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement.

Follow the link for an example how this can be used.

Answer 2

else executes after for providing for wasn't terminated with break:

for i in range(10):
    print i
    if i == 8:
        break # termination, no else    
else:
    print "after for loop"
