Else and if commands

Today we will learn about the else, if, then and elif commands. The if command works just like real life. It works like this:

if < insert condition here>:
< insert action here >

Note: You must indent the line after the if statement and the else statement. Also, you must put a colon after the condition.

So if for example variable "a" is 1 and you want to do something if it is 4, then you write this:

if a == 4:
<
insert action here >

Note: you use one equals sign to set things equal to each other, but you use two to compare them. That is why I used one in the variables post and two in this post.

If you want it to do something if "a" = 4 but somethng else if it isn't, then do this:

if a == 4:
<
insert action here >
else:
<
insert action here >

Note: Always remember to put the colon after else otherwise it won't work.
