This is how to change the file extension:

py> import os
py> filename = "weekly_20160102.csv"
py> newname = os.path.splitext(filename)[0] + ".txt"
py> print(newname)
weekly_20160102.txt


Once you have the new file name, ending with .txt, do you understand how 
to open it and write to it? For example, you might do this:

with open(newname, "w") as f:
    f.write("line 1\n")
    f.write("second line\n")
    f.write("last line\n")


When you exit the "with" block, the file will be automatically closed.

Remember to use \n (newline) at the end of each line.
