Python Loops
Python has two primitive loop commands:
while loops
for loops
The while Loop
With the while loop we can execute a set of statements as long as a condition is true.
Example
Print i as long as i is less than 6:
i = 1
while i
print(i)
i += 1
Run example »
Note: remember to increment i, or else the loop will continue forever.
The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i,
which we set to 1.
The break Statement
With the break statement we can stop the loop even if the
while condition is true:
Example
Exit the loop when i is 3:
i = 1
while i
print(i)
if i == 3:
break
i += 1

The continue Statement
With the continue statement we can stop the
current iteration, and continue with the next:
Example
Continue to the next iteration if i is 3:
i = 0
while i
i += 1
if i == 3:
continue
print(i)
