The text file is "ics2o.txt" and I don't know how to print numbers next to the lines

import random 
print ("----------------------------------------------------------")
print ("Student Name Student Mark")
print ("----------------------------------------------------------")

f = open("ics2o.txt")
for line in f:
  x = len(f.readlines())
  for i in range (x):
    contents = f.read()
    print(str(contents)   str(random.randint(75,100)))

for line in f:
  x = len(f.readlines())
  for i in range (x):
    contents = f.read()
    print(str(contents)   str(random.randint(75,100)))

The problem is that you are reading the file in at least 3 different ways which causes none of them to work the way you want. In particular, f.readlines() consumes the entire file buffer, so when you next do f.read() there is nothing left to read. Don't mix and match these. Instead, you should use line since you are iterating over the file already:

for line in f:
    print(line   str(random.randint(75,100)))

The lesson here is don't make things any more complicated than they need to be.

1. Firstly, doing print("----...") is a bad practice, at least use string multiplication:print("-"*10)
2. Secondly, always open files using 'with' keyword. (u can google it up why)
3. Thirdly, the code:

   with open("ics2o.txt") as f:
       for i,j in enumerate(f):
           print(i,j)
