Python 3 programming tutorial: While Loop

The two distinctive loops we have in Python 3 logic are the "for loop" and the "while loop." Both of them achieve very similar results, and can almost always be used interchangeably towards a goal. Many times it comes down to programmer preference, or is reliant on efficiency. Generally, the for loop can be more efficient than the while loop, but not always.

The idea of the While loop is:
While something is the case, do the following block of code.

This Python 3.3 programming tutorial covers the while loop within Python.

After this lesson you can get this joke)))
A programmer went to the grocery store. His wife said "while you are out, go get some milk"
He never came back.

This small amount of information, helped me ALOT. Thanks man, amazing teacher.

The while loop can also be useful for algorithms that will repeat an unknown number of times, such as factoring a number. Correct me if I'm wrong, but I would say calling them "interchangeable" with a for loop might be a little misleading. 'for' statements iterate over the elements of a sequence or iterable object whereas a while loop only executes if a condition is true. In C++ they are virtually interchangeable, but not so in Python, I think.

thank you this helped me with my Alternative assessment and idk why i dont understad it but you explained it fluently
u earned a sub!!

I love python, it's so much easier than c++, it's great for both begginers and more advanced users. Also, you make a great job at explaining everything, you just won a new subscriber.

Thanks for the Tutorial... Very simplified

[kazimahim]

print("She: Do you really love me?")
print("He: Yes, baby")
print("She: I want you to keep telling me that you love me till I die, baby")
print("He: Not a problem, baby")

# HE DID THIS:
while True:
print("I love you")

Thanks, I wasn't understanding what my teacher explained. This helps alot

Regarding the infinite while True loop - I've run it in Sublime and it didn't stop with CTRL+C. I just highlighted the code, deleted it (or CTRL+X if you like to re-use the code) and pressed CTRL+B.
That did the job for me lol

Love your tutorial! :)

It really bothers me that the incremental operator "++" is not allowed in python...
