Book title project

Hi.iam learning Python recently.can anyone tell me what the problem is with this code?:( file = open("/usercode/files/books.txt", "r") list=file.readline() for i in list: if i==list[len(list)-1]: title=i[0]+str(len(i)) print(title) else: title=i[0]+str(len(i)-2) print(title) file.close()

Or, instead of checking whether there is a "\n" at the end of each line, you could just get rid of them 😉 with open("/usercode/files/books.txt") as file: for line in file: print(line[0] + str(len(line.strip("\n"))))

file = open("/usercode/files/books.txt", "r") list=file.readlines() for line in list : if "\n" in line: print(line[0]+str(len(line)-1)) else: print(line[0]+str(len(line))) file.close() This should work In the first if you replace it with an if \n in i: (you search if there is a new line) Then in the next line (title=i[0]...) you need to subract 1 from the number of charcters because else it would count \n And in the else: you don't need that - 2 The rest should be fine Hope it's helpfull

Or just 3 lines with open("/usercode/files/books.txt") as file: for title in file.readlines(): print(title[0] + str(len(title.strip("\n"))))

_jakubwrz_ I seeeeeee😅😂 I forgot this...I wrote wrong readline instead readlines😐😅 And in else, I had to write -1 instead -2. It works.

A simpler way with 5 lines of code. A simple explanation, loop through all lines, and if a line has trailing/ending "\n" remove it from the count of the length. https://code.sololearn.com/cdaPdMWWeN3W/?ref=app

Just change list=file.readline() to list=file.readlines()

Also you can use .strip() for remove whitespace

file = open("/usercode/files/books.txt","r") rows = file.readlines() pit = len(rows) i = 0 while i < pit: name = rows[i] title = name.strip("\n") lenght = str(len(title)) answer = title[0] + lenght print(answer) i += 1 file.close()

file = open("/usercode/files/books.txt", "r") #your code goes here books=file.readlines() for i in books: if i==books[-1]: value=len(i) else: value=len(i)-1 print(i[0]+str(value)) file.close()

file = open("/usercode/files/books.txt", "r") for line in file: print(line[0]+str(len(line.strip("\n")))) file.close() You add .strip("\n") after line so it does not count \n as character when you are counting the length

Here this worked for me file = open("/usercode/files/books.txt", "r") #your code goes here f = file.readlines() for i in f: x = i[0] if '\n' in i: y = len(i)-1 else: y = len(i) print (x + str(y)) file.close()

This is my solution: file = open("/usercode/files/books.txt", "r") #your code goes here name = file.readlines() var = 1 while (-len(name)+var) <= 0: num = int (-len(name)+var)-1 s = name[num].split(" ") cont = "".join(i[0] for i in s) print (cont) var+=1 file.close()
