if、elif 和 else 条件在我的代码中无法正常工作

Question

    return(greet)

print("Enter your name")
name=input()

if(name is "Saptarshi"):
    greet=greeting(name)
    print(greet)

elif(name is "Gurpreet"):
    greet=greeting(name)
    print(greet)

else:
    print("No greeting for you!")

Answer 1

Use == instead of is.

Python is operator compares two variables and returns True if they reference the same object. If the two variables reference different objects, the is operator returns False.

a = 100
b = a
result = a is b # True

d = 10
e = 10
result = d is e # False
