Counting the number of bytes in lines of a text file.

Question

You are provided a books.txt file, which includes the book titles, each one written on a separate line.

Read the title one by one and output the code for each book on a separate line.

For example, if the books.txt file contains:

Some book
Another book

Your program should output:

S9
A12

Recall the readlines() method, which returns a list containing the lines of the file.

Also, remember that all lines, except the last one, contain a \n at the end, which should not be included in the character count.

file = open("/usercode/files/books.txt", "r")

#your code goes here

for i in file:

    m=len(i)

    print("{0}{1}".format(i[0],m)

file.close()

I'm having troubles with the last line because as the last one doesn't have the '\n'.

So, in that case my result is

   S17 and the result has to be S18.

Answer 1

Try using strip() on i before getting its len(). This will remove the '\n' from the string if present.
