Book title project

Question

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()

Answer 1

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"))))

Answer 2

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

Answer 3

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"))))

Answer 4

Mr Myth thank you🙏

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

Answer 7

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.

Answer 8

Oh really? I tried it before i posted it, but I will try again

Answer 9

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

Answer 10

Also you can use .strip() for remove whitespace

Answer 11

I tested the code again, it works for me... idk

\n take only - 1

Answer 12

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()

Answer 13

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()

Thank you but it doesn't work:(

Answer 15

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

Answer 16

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()

Answer 17

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()

Answer 18

file = open("/usercode/files/books.txt", "r")
for line in file:
words = line.split()
i = ""
for word in words:
i += word[0]
print(i)

file.close()

Answer 19

file = open("/usercode/files/books.txt", "r")
for line in file:
words = line.split()
i = ""
for word in words:
i += word[0]
print(i)

file.close()
