For loops are traditionally used when you have a block of code which you want to repeat a fixed number of times. The Python for statement iterates over the members of a sequence in order, executing the block each time. Contrast the for statement with the ''while'' loop, used when a condition needs to be checked each iteration, or to repeat a block of code forever. For example:
For loop from 0 to 2, therefore running 3 times.
for x in range(0, 3):
print("We're on time %d" % (x))
When you have a block of code you want to run x number of times, then a block of code within that code which you want to run y number of times, you use what is known as a "nested loop". In Python, these are heavily used whenever someone has a list of lists - an iterable object within an iterable object.
for x in range(1, 11):
for y in range(1, 11):
print('%d * %d = %d' % (x, y, x*y))
