问候程序引发NameError

varname = input("what is your name?: ") 
print ("Hello", varname)

有没有人知道为什么这不会工作？只是打印问候程序引发NameError

Traceback (most recent call last): 
    File "C:/Users/sfawcett/Desktop/python.py", line 1, in <module> 
    varname = input("what is your name?: ") 
    File "<string>", line 1, in <module>

input()评估字符串。要获取原始值，你应该使用raw_input()

在python3： -

In [4]: varname = input("what is your name?: ") 
what is your name?: lewis 

In [5]: print ("Hello", varname) 
Hello lewis

在python2

： -

阅读here about input

In [185]: varname = raw_input("what is your name?: ") #don't use `input()` 
what is your name?: lewis 

In [186]: print ("Hello", varname) 
('Hello', 'lewis')
