You may be thinking: I already know how to use IF statements in Python.
Yes, you do.
So, why am I writing this?
Well, if you have just started learning Python, or if you have never used it before, here are some tips that may help you:
If you want to test if a variable is True or False, you can just do this:
variable1 = True variable2 = False if variable1: print("The first variable is True") if not variable2: print("The second variable is False")
You can do the same thing to test if there is a value assigned to the variable:
variable1 = "Some text" variable2 = 1 variable3 = "" if variable1: print("The first variable has a value assigned to it") if variable2: print("The second variable has a value assigned to it") if not variable3: print("The third variable has not a value assigned to it")
To check if a value is inside a list, use this:
numbers = ["one", "two", "three", "four", "five"] if "four" in numbers: print("The number four is in the list")
Remember: "one" is numbers, not numbers. This last one is "two".
Atention: to check if a value is equal to another, you can't use the examples above. Use
x == y.
