在使用字符串if语句

Question

我需要在if语句被用于用户输入的方式：

print("Hello, World!") 

name = input("What is your name?") 

hobby = input("Cool, so " + name + " what do you do you for fun? You can say something like play, work, learn, etc.") 

play = 'play' 
work = 'work' 
learn = 'learn' 

if hobby = play 
    print('awesome') 

elif hobby = work 
    print('must be busy') 

elif hobby = learn 
    print('ha, me too') 

Answer 1

的if，elif和else报表必须由:被终止。另外==是用于比较，=是转让。所以

if hobby == play: 
    print('awesome') 

elif hobby == work: 
    print('must be busy') 

elif hobby == learn: 
    print('ha, me too') 

Answer 2

您可以通过编码

if hobby == 'play': 
    print('awesome') 

OR

if hobby == play: 
    print('awesome') 

Answer 3

在你的解决方案你缺少:和==运营商，但在你的情况下删除该任务，而不是其他人，如果梯子，你可以用字典。

from __future__ import print_function 

actions = {'play': 'awesome', 'work': 'must be busy', 'learn': 'ha, me too', } 

if hobby in actions: 
    print(actions[hobby]) 
else: 
    print("default case") 

OR

from __future__ import print_function 

actions = {'play': 'awesome', 'work': 'must be busy', 'learn': 'ha, me too', } 

try: 
    print(actions[hobby]) 
except KeyError: 
    print("default case")
