如何复制文本文件内容并将其转换为行

Question

I am trying to make a program that is able to copy a text file and then write out another text file with the same content but changed. For example:

SAS- numbers
PR  - 123
SE  - 456
TE  - 789

The one above is the original text file, but I would like to know how can I make it so it looks like this when my program writes out the copy of the original one:

numbers;123;456;789

This is what I have for now:

    openfile = input('Enter the input file: ')
    outputfile = input('Enter the output file: ')

    output = open(outputfile,'w')
    with open(openfile, 'r') as inputfile:
                output.write(inputfile.read())
    output.close()

Any advice would be really helpful!

Look into my Below code. This might help you.

input_data = ""
with open("input.txt", "r") as f:
    input_data = f.readlines()

output_data = ";".join([line.split("-")[1].rstrip("\n").strip() for line in input_data])

with open("output.txt", "w") as f:
    f.write(output_data)
