Help me with this...

Question

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

#your code goes here
book_titles = file.readlines()
total_books = len(book_titles)
book_index = 0

for i in range(total_books):
book_name = book_titles[i]
first_letter = book_name[0]
if i < total_books:
name_length = len(book_name)-1
book_code = first_letter + str(name_length)
print(book_code )

file.close()

Answer 1

Because the for loop infex „i“ beginning from 0. So the last item will have the index len(array)-1.

Answer 2

You have to pay attention to which line should be where so that it can be influenced by "if" or not.

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

#your code goes here
book_titles = file.readlines()
total_books = len(book_titles)
book_index = 0

for i in range(total_books):
book_name = book_titles[i]
first_letter = book_name[0]
if i < total_books:
name_length = len(book_name)-1
book_code = first_letter + str(name_length)
print(book_code )

file.close()
