原英文帮助文档:
input
([prompt])
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.

中文解释:
input
([prompt])
如果prompt参数存在,它将被写入标准输出,而不带尾随换行符。然后,该函数从输入中读取一行,将其转换为字符串(去掉尾随的换行符),并返回该行。
当读取到EOF时,将引发EOFError
。例子:
>>> s = input('--> ') --> Monty Python's Flying Circus >>> s "Monty Python's Flying Circus"
关于EOFError:
exception EOFError Raised when the input() function hits an end-of-file condition (EOF) without reading any data. (N.B.: the io.IOBase.read() and io.IOBase.readline() methods return an empty string when they hit EOF.)
当input()函数在不读取任何数据的情况下达到文件结束条件(EOF)时引发。(注意:io.iobase.read()和io.iobase.readline()方法在到达EOF时返回空字符串。)
如果读取到readline模块, input()
将使用它来提供精细的行编辑和历史特征。
示例:
>>> input() s 's' >>> a = input("please input str") please input str99 >>> a '99' >>> a = input("please input str\n") please input str 100 >>> a '100' >>>

注意:在Python 2.x 和Python 3.x版本中input函数的区别:
所以在Python 2.x 中常见到的是raw_input() ;
