How Do IF Statements Work in Python?
An IF statement evaluates the value of a variable or object to determine whether an action should be performed. Here's an example:
IF (x == 0 ) THEN x=x+1
In this case, that IF statement is evaluating the value of X. If X equals zero, then it increases the value of X to one. We can also use an ELSE clause with that IF statement for additional actions. For instance, you could add an ELSE statement to the end of that IF statement to increment the value of X by two. So, if X is any other value than zero (EG. It has a value of one), the code will increase the value of X by two (EG. It will add 2 to the current value of one for X).
