pythoninputnameerror_使用input（）时出现NameError

So what am I doing wrong here?

answer &＃61; int(input("What is the name of Dr. Bunsen Honeydew&＃39;s assistant?"))

if answer &＃61;&＃61; ("Beaker"):

print("Correct!")

else:

print("Incorrect! It is Beaker.")

However, I only get

Traceback (most recent call last):

File "C:\Users\your pc\Desktop\JQuery\yay.py", line 2, in

answer &＃61; int(input("What is the name of Dr. Bunsen Honeydew&＃39;s assistant?"))

File "", line 1, in

NameError: name &＃39;Beaker&＃39; is not defined

解决方案

You are using input instead of raw_input with python 2, which evaluates the input as python code.

answer &＃61; raw_input("What is the name of Dr. Bunsen Honeydew&＃39;s assistant?")

if answer &＃61;&＃61; "Beaker":

print("Correct!")

input() is equivalent to eval(raw_input())

Also you are trying to convert "Beaker" to an integer, which doesn&＃39;t make much sense.

You can substitute the input in your head like so, with raw_input:

answer &＃61; "Beaker"

if answer &＃61;&＃61; "Beaker":

print("Correct!")

And with input:

answer &＃61; Beaker # raises NameError, there&＃39;s no variable named Beaker

if answer &＃61;&＃61; "Beaker":

print("Correct!")
