Python 内建函数 - input([prompt])

Manual

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised. Example:

>>>
>>> s = input('--> ')  
--> Monty Python's Flying Circus
>>> s  
"Monty Python's Flying Circus"

If the readline module was loaded, then input() will use it to provide elaborate line editing and history features.

直译

如果出现prompt参数，它将不后缀换行符写入到标准输出。随后函数根据输入读取一行，将它转化为字符串（去掉尾缀换行符），并返回该值。当读入发生EOF时，引发EOFError。例如：

>>>
>>> s = input('--> ')  
--> Monty Python's Flying Circus
>>> s  
"Monty Python's Flying Circus"

如果加载readline模块，那么input()将会使用它来提供详细的行编辑和历史特征。
