Why is my IF statement in Python not working? [duplicate]

So I have an assignment to draw a flag using Turtle in Python. I have a variable named flagName and you can use it to select what type of flag you want to draw. But the problem is, the IF statement isn't working! No matter what I type in the variable, it will always print "usa" (My other flags are still work in progress).\
Someone please help me!

penup()

flagName = "USA"




if flagName == "USA" or "usa" or "United States of America" or "united states of america" or "United States of America" or "us" or "US":
        #setup location
        print("usa")
elif flagName == "China" or "china":
        #setup location
        print("china")
elif flagName == "Germany" or "germany":
        print("germany")
elif flagName == "Canada" or "canada":
