The document summarizes while loops in Python. It explains that while loops execute a set of statements as long as a condition is true. An example is provided to print the numbers from 1 to 5 using a while loop. It also discusses the break, continue, and else statements that can be used within while loops to control program flow.

Python While Loops
Python Syntax Python Comments Python Variables Python Data Types ❮ Previous Next ❯ Python Numbers Python Casting Python Strings Python Booleans Python Loops Python Operators Python has two primitive loop commands: Python Lists Python Tuples while loops Python Sets for loops Python Dictionaries Python If...Else Python While Loops The while Loop Python For Loops Python Functions With the while loop we can execute a set of statements as long as a condition is true. Python Lambda Python Arrays Python Classes/Objects Example Get your own Python Server Python Inheritance Print i as long as i is less than 6:
i = 1 while i < 6: print(i) i += 1

Note: remember to increment i, or else the loop will continue forever.
COLOR PICKER 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 < 6: 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 ADVERTISEMENT
Continue to the next iteration if i is 3:
i = 0 while i < 6: i += 1 if i == 3: continue print(i)
Try it Yourself »
The else Statement
With the else statement we can run a block of code once when the condition no longer is true:
Example Print a message once the condition is false:
i = 1 while i < 6: print(i) i += 1 else: print("i is no longer less than 6")
