UnboundLocalError：分配前引用的局部变量'print'

Question

嘿，大家我介绍python编程，我们正在做第一个独立的代码。分配如下：

Prompt the user for his or her name. Then prompt the user for two numbers and then perform a mathematical operation of your choice on them. Make sure the program works with decimal numbers, and that you print a full equation in response, not just the result: Enter a number: 2.3 Enter another number: 3.6 2.3 – 3.6 = -1.3

所以我进入：

def main1(): 
print("This is program 1!") 
name = input("Please enter your name: ") 
print("Pleased to meet you,", name ,"!") #next line def main2(): 
print("This is program 2!") 
import math 
number = input("Enter a number: ") 
number = float(number) 
numberr = input("Enter another number: ") 
numberr = float(numberr) 
print = ("number + numberr") 

我不停的得到这个：

UnboundLocalError: local variable 'print' referenced before assignment 

帮助！

Answer 1

您尝试将值分配给print。

您写道：

print = ("number + numberr") 

但你实际上的意思是：

print(number + numberr)
