Python：从文件中读取数据

Question

I have to read data from a text file from the command line. It is not too difficult to read in each line, but I need a way to separate each part of the line.

The file contains the following in order for several hundred lines:
String (Sometimes more than 1 word)
Integer
String (Sometimes more than 1 word)
Integer

So for example the input could have:

Hello 5 Sample String 10

The current implementation I have for reading in each line is as follows... how can I modify it to separate it into what I want? I have tried splitting the line, but I always end up getting only one character of the first string this way with no integers or any part of the second string.

with open(sys.argv[1],"r") as f:
    for line in f:
        print(line)

The desired output would be:

Hello
5
Sample String
10

and so on for each line in the file. There could be thousands of lines in the file. I just need to separate each part so I can work with them separately.

Answer 1

The program can't magically split lines the way you want. You will need to read in one line at a time and parse it yourself based on the format.

Since there are two integers and an indeterminate number of (what I assume are) space-delimited words, you may be able to use a regular expression to find the integers then use them as delimiters to split up the line.
