Simple Python Tutorial to compare if and while #if #while #python #simple

Please like the video if it helps you :)

Simple python example and short video to illustrate similarity and differences between "if" and "while". It uses very simple example to focus on how the 2 differs. It first show how to do some user input checking with "if" statement and explain why
it is unable to ensure user has entered a valid input (int in this case). It then went on to explain how we can just change
the "if" to "while" to solve the problem. It shows that "while" works similarly with an "if" statement where there is a
test condition to decide whether to execute the statements within the body. The only difference if that "if" statement
only perform the test condition check once but "while" will perform it repeatedly until the test condition become False.
Thus a "while" can be seen as a "repeated if" statement running.

Beginners tends to confuse "if" and "while" and tends to use "if" when a "while" is more relevant.
The syntax for both are largely similar and the the way it control the flow of the code as well.
This short video hopes to highlight the differences so that it is clearer when they should be used.

== Syntax of "if" ==
if(test condition):
indent == 1st statement of Body statement
indent == ...
indent == last statement of Body statement

== Syntax of "while" ==
while(test condition):
indent == 1st statement of Body statement
indent == ...
indent == last statement of Body statement

Hope these inputs are helpful for you.

0:00 - "if" only checks condition once but we need to repeat checking
02:10 - "while" works like "repeat" "if" command
02:37 - replace "if" with "while" to make it work
