how to print the no of letters including space in each element in list in python-CodePudding

so I making an app that prints the first letter and the no of words including space in each element in a list in python in the same line

so the list is a file which with the help of readlines() I have converted into a variable that can be used as a list this is my code that can print the first letter of each element in that list so now I just have to print the no of letters in each element in the list I will provide my code, current output, expected output, and the file


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

    #your code goes here
    contentlines = file.readlines()
    content = file.read()
    no_of_words = str(len(contentlines[0]))

    for first_letter in contentlines:
        print(first_letter[0])

    file.close()

current output

H
T
P
G

expected output

H12
T33
P18
D16

the file content

Harry Potter
The Red and the Black by Stendhal
Pride and Prejudice
David Copperfield

IIUC, you can simplify your code to loop and print at the same time:

with open('/usercode/files/books.txt', 'r') as f:
    for line in f:
        L = len(line.rstrip('\n'))
        print(f'{line[0]}{L}')

output:

H12
T33
P19
D17

With a little bit of modification on your own code:

file = open("books.txt", "r")

#your code goes here
contentlines = file.readlines()
content = file.read()

for line in contentlines:
  no_of_words = len(line)-1
  print(line[0], no_of_words, sep="")

file.close()

Output

H12
T33
P19
D16

Note that, in the len(line)-1, the -1 refers to the break line shown by "\n". It is counted as one character.
