Working with Files: Intermediate Python

Question

"Working with Files

You are given a books.txt file, which includes book titles, each on a separate line.
Create a program to output how many words each title contains, in the following format:
Line 1: 3 words
Line 2: 5 words
...

Make sure to match the above mentioned format in the output."

I managed to found how many words each title contains, but I am having a trouble in identifying the lines in the format above. Here is my try:

"with open("/usercode/files/books.txt") as f:
cont = f.readlines()
for line in cont:
words = line.split()
for line in list(cont):
print('Line ' + str(cont.index(line)) + ': ' + str(len(words)) + ' words')"

Can anybody help me? Thanks in advance

Answer 1

Or maybe better with the enumerate() function:

with open("/usercode/files/books.txt") as f:
cont = f.readlines()
for n, line in enumerate(cont):
words = line.split()

print('Line ' + str(n+1) + ': ' + str(len(words)) + ' words')

Answer 2

What is the 2. loop for?
Maybe this is working as expected?

with open("/usercode/files/books.txt") as f:
cont = f.readlines()
n = 0
for line in cont:
words = line.split()
n += 1
print('Line ' + str(n) + ': ' + str(len(words)) + ' words')
