Answer 1

Hi dear!
The reason it's not working is because you're returning all characters as list items.
You may find the join() method useful in this case. It joins a list of strings with another string as a separator.
So, your print statement needs to be like this

print("".join(l))

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

lines = file.readlines()

line_list = line.split(" ")
nickname = []

nickname.append(word[0], end="")
file.write(nickname)
