Python - how to replace occurances in text files?

Question

I am working on my school work for 'Intro to Scripting' and I am stuck on how to replace in a text file.

The challenge is asking me to read the contents of the text file, which I did with the code below:

filepath = I

file1 = open(filepath, 'r')
print(file1.read())
file1.close()

Now it's asking me to replace the variable set for 'S' with the variable set for 'T', and I can't for the life of me figure out how to do this.

Edit: This is an online class, so peer collaboration is non-existent, we also use Codio for this work, and nothing I've tried from other questions asked has worked, nor does any of the class reading give examples.

Yes, the challenge is asking me to read the file, then replace the variables. — Heather, Feb 27 '19 at 06:39
# Get the filepath from the command line import sys I= sys.argv[1] O= sys.argv[2] S= sys.argv[3] T= sys.argv[4] # Your code goes here — Heather, Feb 27 '19 at 06:47

If I am Correct If you want to Just Replace S With T and save output in another file use following code

f1 = open('data.txt', 'r')
f2 = open('output.txt', 'w')
for line in f1:
    f2.write(line.replace('S', 'T'))
f1.close()
f2.close()
