SyntaxError - 无法分配给函数调用

Question

我想添加.lower()来电，所以不要执行以下操作：

variable_name = input()
if variable_name == "example" or variable_name == "Example":
    print ("whatever I want")

我想这样做

variable_name.lower() = input()
if variable_name == "example":
    print ("whatever I want")

问题是，每当我这样做并运行程序时，它告诉我它不能分配给函数调用。我留下了一段代码供你查看。

#Variables and Imports Declerations
import sys
import os
awnser.lower() = " "
score = 0
#----------------------------------

while playagin == "yes":

    #Welcome Message and Title
    print ("GeneralQuiz")
    print ("Welcome to GeneralQuiz!")

    #Question 1
    print ("What is the 10th letter of the alphabet?")
    answer.lower() = input ()

    if answer == "j":
        print ("Congratulations! + 1 Score!")
        score = score +1
    else:
        print("Incorrect! The answer is J!")

或

#Variables and Imports Declerations
import sys
import os
awnser = " "
score = 0
#----------------------------------

while playagin == "yes":

    #Welcome Message and Title
    print ("GeneralQuiz")
    print ("Welcome to GeneralQuiz!")

    #Question 1
    print ("What is the 10th letter of the alphabet?")
    answer.lower() = input ()

    if answer == "j":
        print ("Congratulations! + 1 Score!")
        score = score +1
    else:
        print("Incorrect! The answer is J!")

Answer 1

与错误一样，您无法分配给函数调用。 variable_name.lower()是函数调用。

您已将通话置于错误的位置。您想在input：

的结果上调用它

variable_name = input().lower()
