This is using Python can you please explain to me in detailthis is for study guide can you make a simple solution for this using for loop or if statement.

Write a program that read from an input file, and write to an output file. The contents of this output file should be ONLY the even characters on all of the input files odd lines to the output file. If that works and makes sense, now add code to write all of the odd characters on all of the input files even lines to the output file. *Note: odd and even lines in the input file are also going to be odd and even lines in the output file, respectively. (see below) The contents of this input file should be:

1212121212121212121212121212121212

3434343434343434343434343434343434
