How to delete a string from all files in a directory

May 30, 2022

I want all files in directory "path" to have the string "error" removed from them and the result to be saved in the same file that was editted. My current code (below) ends up clearing up the entire file, rather than just removing the string and keeping everything else the same.

import os


path = "path"
files = os.listdir(path)
error = "string"


for index, file in enumerate(files):
    with open(os.path.join(path, file)) as fin, open(os.path.join(path, file), "w+") as fout:
        for line in fin:
            line = line.replace(error, "f")
            fout.write(line)

>Solution :

import os

path = "path"
files = os.listdir(path)
error = "string"

for index, file in enumerate(files):
    with open(os.path.join(path, file), 'r') as fin:
       d = din.read()
    with open(os.path.join(path, file), "w") as fout:
        d = d.replace(error, "")
        fout.write(d)
