line[0] prints the first letter of A line. But I Also Require Len of that element. Eg. B5 for BOOKS.

Question

file = open("/usercode/files/books.txt", "r")
for line in file:
print(line[0]+file.write("/usercode/files/books.txt"))#This don't works, don't Concatenate

Answer 1

check my updated answer (to convert length to string): I forgotten the str() call ^^

Answer 2

you probably should check your closing parenthesis ^^

Answer 3

then use:

print(line[0]+str(len(line)-(1 if line[-1]=='\n' else 0)))

it will substract 1 if last line char is the new line char ;)

Answer 4

you don't want to use file.write(), as you don't want to modify the file ^^

and even by writing in a temporary file, you will get the line length plus one (the new line)...

if you want to do so, you need to open a temporary file with 'w' flag instead of 'r'

Answer 5

just use the strip() method on the string to remove the '\n' then get its length

print(line[0]+str(len(line.strip())))

Answer 6

print(line[0]+str(len(line)))

Answer 7

visph I tried but it cAnnot concatenate string and numbers eg. In BOOKS, B and 5 is concatenated. But How

Answer 8

Answer 9

It is close. EXPECTED Output is H12, T16, P19, G18 But I got H13, T17, P20, G18

Answer 10

Seems like file.write() need to be used to print the length insteAd of length function

Answer 11

file.write() will write into file ^^

Answer 12

How do I use readlines and print(file.write()) to Achieve the sAme Above

Answer 13

Seems like need more in-depth AnAlyse. ThAnks much

Answer 14

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.
