问题描述
我知道如何提高错误类型，但如果有人在raw_input的字符串中输入一个整数，我无法弄清楚我应该使用哪个错误。
这是我的代码：
try:
print "Welcome to my Quiz!"
points = 0
#Asks the user the first question and check to see if the answer is right and gives them a point if they are
question1 = raw_input("Here's question #1! What is the name of Spongebob's pet?")
if (question1.lower()) == "gary":
print "You are correct!"
points +=1
else:
print "You are wrong!"
#Asks the user the second question and check to see if the answer is right and gives them a point if they are
question2 = raw_input("Here's question #2! Whos is Spongebob's best friend?")
if (question2.lower()) == "patrick":
print "You are correct!"
points +=1
else:
print "You are wrong!"
#Asks the user the third question and check to see if the answer is right and gives them a point if they are
question3 = raw_input("Here's question #3! Where does Spongebob work?")
if (question3.lower()) == "krusty krab" or (question3.lower()) == "the krusty krab":
print "You are correct!"
points +=1
else:
print "You are wrong!"
print "Thanks for playing my quiz! You got", points, "answers right out of 5! Nice job!"
except ValueError, errorvar:
print errorvar
except NameError:
print "Please enter a number for the correct variables, thanks"
except:
print "An error has occurred"

总是返回一个str 。
所以如果有人输入123 ，结果将是'123' （注意引号）。
在其他情况下，您以某种方式有一个返回int的函数，其中代码需要一个str （例如您如何在raw_input的结果上立即调用lower ）， int不会有一个lower方法，因此尝试调用应该会导致AttributeError .
>>> (0).lower()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'int' object has no attribute 'lower'
