Python- How to make an if statement between x and y?

Question

I've recently been breaching out to Python, as C++ is fun and all, but python seems kinda cool. I want to make Python do something as long as the input is between a certain number range.

def main():
    grade = float(input("“What’s your grade?”\n:"))
    if grade >= 90:
        print("“You’re doing great!”")
    elif(78 >= grade <= 89):
        print("“You’re doing good!”")
    elif(77 >= grade > 65):
        print("You need some work")
    else:
        print("Contact your teacher")

main()

The problem arises when I'm making the elif statement, I can't make it so Python only prints the "doing great" statement as long as the grade is between 65 and 89. How would you go about doing ranges of numbers?

Answer 1

In Python you can do something like this to check whether an variable is within a specific range:

if 78 <= grade <= 89:
    pass
