You may use raw_input(“prompt”) function. The input will be string by default. You need to convert it into int, boolean, float etc etc as per your requirement. If you are taking multiple input at a same time delimited by space, use: [x,y]=raw_inpu

This behaviour will happen even if it is a valid escape sequence for a regular expression. The solution is to use Python’s raw string notation for regular expression patterns; backslashes are not handled in any special way in a string literal prefixed with ‘r’.

while(scanf()!=EOF)的作用是,当scanf返回EOF时退出循环读取输入的操作。也就是当遇到文件结尾,如果用作标准输入时就是当在终端输入了EOF时结束操作。对于此,python并没有相同功能的系统函数而是需要由自己判断。
