Can you rate my code for "book title" pls

Question

Here is my code. It is working, but i feel it is not the best way for writing:

file = open("/usercode/files/books.txt", "r")
lines = file.readlines()
l = len(lines)
i = 0
while i < (l-1):
print(str(lines[i])[0]+str(len(lines[i])-1))
i+=1
print(str(lines[i])[0]+str(len(lines[i])))
file.close()

Answer 1

Overall its GOOD.

You can update this thing:
>> since you know the number of iteration then why use while loop instead of for loop

In case you wanna see my one,

file = open("/usercode/files/books.txt", "r")
x = file.read()
x = x.split("\n")
for i in x:
print(i[0]+str(len(i)))
file.close()
