英文文档:
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
说明:
1. 如果提供了promat参数,首先将参数值输出到标准的输出,并且不换行。函数读取用户输入的值,将其转换成字符串。
>>> s = input('please input your name:')
please input your name:Ain
>>> s
'Ain'
