Loops

For loops

for cur_element in some_sequence:
    suite
else:
    suite

• Iterates over the elements of a sequence--string, tuple, list, or other iterable object--in the order that they appear in the sequence.
• The else suite is executed after the for loop exits, unless the loop exited with a break.
• Use the built-in range function to iterate a number of times.

for element in some_list:
    print element
else:
    print 'End of list'

While loop

while expr:
    suite

while expr:
    suite
else:
    suite

• The else suite is executed after the while loop exits, unless the loop exited with a break.

Jump statements

• break  : Immediately exits the for or while loop, without executing the else suite, if one is present.
• continue  : Immediately starts the next iteration of the for or while loop.
