I have some textfiles in a folder and I want to search all of them for names between row 4 and 20 and then copy the ones containing one of those names to a different folder. With my code I only get an empty result file even though I know the keywords are in my folder. What could be the problem with this code for Python 3?
from os import system, listdir, path
import codecs
FILE = open('C:\\Users\\Admin\\Desktop\\Test\\Result.txt', 'w')
desktop_dir = path.join('C:\\Users\\Admin\\Desktop\\test\\')
for fn in listdir(desktop_dir):
fn_w_path = path.join(desktop_dir, fn)
if path.isfile(fn_w_path):
with open(fn_w_path, "r") as filee:
for line in filee.readlines():
for word in line.lower().split():
if word in {'James',
'Tim',
'Tom',
'Ian',
'William',
'Dennis',}:
FILE.write(word + "\n")
FILE.close()
import os
import shutil
for root, dirs, files in os.walk("test_dir1", topdown=False):
for name in files:
current_file = os.path.join(root, name)
destination = current_file.replace("test_dir1", "test_dir2")
print("Found file: %s" % current_file)
print("File copy to: %s" % destination)
shutil.copy(current_file, destination)

I want to get my script to read a list of names from a list(txt), then search for those in a selected folder with subfolders, then copy and paste those files to another selected folder. My script running without error but no result.
My script:
import os
import os.path
import shutil
textFile = ("D:\\Test\\list.txt")
sourceFolder = ("D:\\Test")
destinationFolder = ("D:\\")
filesToFind = []
with open(textFile, "r") as tx:
for row in tx:
filesToFind.append(row.strip())
for root, dirs, filename in os.walk(sourceFolder):
if filename in filesToFind:
f = os.path.join(root, filename)
shutil.copy(f, destinationFolder)
Haven’t test it but I think this will work - change this:
for root, dirs, filename in os.walk(sourceFolder):
if filename in filesToFind:
f = os.path.join(root, filename)
shutil.copy(f, destinationFolder)
To this:
for root, dirs, filenames in os.walk(sourceFolder):
for filename in filenames:
if filename in filesToFind:
f = os.path.join(root, filename)
shutil.copy(f, destinationFolder)
# Same code using glob #
## More efficient and also tested one ##
## One more feature added- checks file name given present or not ##
import os
import os.path
import shutil
import glob
textFile = ("D:\\Test\\list.txt")
sourceFolder = ("D:\Test")
destinationFolder = ("D:\\")
f = open(textFile, "r").readlines()
for i in f:
ListFile= glob.glob(os.path.join(sourceFolder,"**",i.strip()),recursive=True)
if len(ListFile):
print(ListFile[0],destinationFolder,os.path.basename(ListFile[0]))
destinationfile=os.path.join(destinationFolder,os.path.basename(ListFile[0]))
shutil.copyfile(ListFile[0],destinationfile)
else:
print(i,"-File not found")
There are text files of various names in the folder 'a'. I want to read all of these text files and add the letter 'b' to each text file. What should I do?
cwd = os.getcwd()
input_dir = os.path.join(cwd, "my .txt files dir")
sorts = sorted(glob(input_dir), key = lambda x:(len(x) , x))
for f in sorts :
f = open(input_dir, 'a')
data = "add text"
f.write(data)
f.close()
Append data to file:
- first: get all file in folder a.
- second: find extension with .txt.
- third: open it and do something('append', or 'rewrite').
Demo:
import os
# your .txt files dir
path = 'a'
# append data what you want
appendData = 'b'
fileNames = list(os.walk(path))[0][2]
fileNames.sort(key=len)
fileNums = len(fileNames)
# your dst file extension
fileExt = '.txt'
# # Extract extension from filename
# fileExt = os.path.splitext(fileNames[0])[1]
for fileName in fileNames:
if fileName.endswith(fileExt):
fileFullPath = os.path.join(path, fileName)
with open(fileFullPath, 'a') as f:
f.write(appendData)
Like the others said, this is an easy question that could easily be find on google. Anyway here's how to do it:
from os import listdir
from os.path import isfile, isdir, join
files = [file for file in listdir("files") if isfile(join("files", file))]
directories = [directory for directory in listdir("files") if isdir(join("files", directory))]
print(files)
for file_name in files:
try:
file = open("files/" + file_name, "a")
file.write("b")
file.close()
except IOError as err:
print("Could not open file because : ", err)
Replace "file" with the directory where your files are or the path to that directory like "directory0/directory1/directory_with_files"
Avoid to open files with
f = open(input_dir, 'a')
f.close()
Instead
with open(input_dir, 'a') as inputFile:
Do something
Also what you want is
import os
import glob # We will use this module to open only .txt files
path = 'your/path'
for filename in glob.glob(os.path.join(path, '*.txt'))
with open(filename, 'a') as inputFile:
inputFile.write('b')
I'm getting an error while trying to copy files from a single source directory which contains bug fixes: /home/saurabh/testbed/patch_dir/ to multiple destination directories: app_dir_1 and app_dir_2.
Both these directories are exact replicas of each other.
The script does the following:-
Read lines from a text file into a list. Each line contains the name of one component. In this case: ['file1.class', file2.html]
Search value at each index recursively, starting from a particular directory:
/home/saurabh/testbed/dest_dir/
Take a backup of these files wherever they are found by appending ddMonyyyy to their extension.
Copy files from directory which contains patched components: /home/saurabh/testbed/patch_dir/
to the directory where backup was taken earlier

Appreciate any help to fix the code.
Figured it out !!

content = [x.strip() for x in content]
print('File contents:')
print(content)

source_dir = '/Users/saurabhm/Desktop/Python/testbed/patch_dir/'

print(os.path.join(root, filename))
dir_list.append(root)
current_file = os.path.join(root, filename)
backup_file = os.path.join(root, filename + suffix)
#print(current_file, backup_file)
os.rename(current_file, backup_file)
#print(source_dir + filename + "\t" + root)
shutil.copy2(source_dir + filename, root)
os.chmod(root + '/' + filename, 0o750)
print("\n" + "Backup of all files complete!")
print('Backup of ' + str(len(dir_list)) + ' files taken recursively')
print('Number of files mentioned in text file: ' + str(len(content)) + '\n')
Once patched components are received over email, they are copied to a directory in the respective server. All these files are consolidated in a single directory (patch_dir)
Backup of existing files (having the same name and are present in "dest_dir") are taken wherever they are found, following which each file is copied from "patch_dir" to the directories inside "dest_dir", where their backup was taken.
I'm trying to find and replace texts in all sub directorys of the given directory and here is my code.
import os
folderLocation = "C:\\Users\\josh\\Desktop\\target\\xml\\"
divider = "\\"
pseudoDictionaryKey = []
pseudoDictionaryValue = []
with open("C:/Users/josh/Desktop/FILENAMES.txt", "r") as fi:
for line in fi:
tokens = line.strip().split("-->")
pseudoDictionaryKey.append(tokens[0])
pseudoDictionaryValue.append(tokens[1])
for subdir, dirs, files in os.walk(folderLocation):
for fileIn in files:
if fileIn in pseudoDictionaryKey:
os.rename(folderLocation + subdir, folderLocation + pseudoDictionaryValue[pseudoDictionaryKey.index(fileIn)])
for subdir, dirs, files in os.walk(folderLocation):
for fileIn in files:
result = ""
with open(folderLocation + fileIn,"r") as fi:
result = fi.read()
for i, value in enumerate(pseudoDictionaryKey):
result = result.replace(pseudoDictionaryKey[i],pseudoDictionaryValue[i])
with open(folderLocation + fileIn,"w") as fo:
fo.write(result)
It finds and replaces the texts but it does not knows how to enter subdirs I want it to rename the texts in every files inside the directory and sub directorys like Open every file inside the directory not just the ones defined in FILENAMES.txt
Suppose I have a text file aiq_hits.txt.
Each line in this file corresponds a filename
ant1.aiq
ant2.aiq
ant3.aiq
ant4.aiq
I want to match each line of my textfile (ant1.aiq,ant2.aiq and so on) with filenames which are present at some specific place(R:\Sample) and extract matching files into some other place (R:\sample\wsa).
I have an idea that I need to use functions like os.walk() and fnmatch.fnmatch(), shutil.copy() but I am not able to implement them
My code:
import os
import shutil
import fnmatch
with open("aiq_hits.txt","r") as in_file:
for line in in_file:
I am stuck here
import os
import shutil
sourceDir = "R:\\Sample"
targetDir = "R:\\Sample\\wsa"
existingFiles = set(f for f in os.listdir(sourceDir) if os.path.isfile(os.path.join(sourceDir, f)))
infilepath = "aiq_hits.txt"
with open(infilepath) as infile:
for line in infile:
fname = line.strip()
if fname not in existingFiles: continue
shutil.move(os.path.join(sourceDir, fname), os.path.join(targetDir, fname))
I hope this will suffice:
import os
def match_files(url,file_read, dest):
f = open(file_read, 'rb')
file_list = os.listdir(url)
print(file_list)
saved_path = os.getcwd()
print("Current working directory is " + saved_path)
os.chdir(url)
match = []
for file_name in f:
file_name = file_name.strip()
if file_name in file_list:
match.append(file_name)
os.rename(os.path.join(url, file_name), os.path.join(dest, file_name))
os.chdir(saved_path)
print match
here, url is source directory or folder from which u want to match files, file_read is the name of file (with path) in which list of file names is given, dest is the destination folder.
this code moves the matching files from url to dest, i.e. these files won't remin in url after running the code.
Alternatively you could use the glob module which allows you to enter in a expression for the file name\extension which will then return a list that you can loop over.
I'd use this module if the source directory can have files with the same extension that you want to exclude from being looped over
Also I'm assuming that the file name list is not large and so storing it in a list wont be an issue
eg (I haven't tested the below )
from glob import glob
import os
import shutil
src = 'R:\\Sample'
dst = "R:\\Sample\\wsa"
in_file_list = "aiq_hits.txt"
list_Of_files = glob(os.path.join(src, 'ant*.aiq'))
data = []
with open(in_file_list) as reader:
data += reader.readlines()
for row in list_Of_files:
file_path, file_name = os.path.split(row)
if file_name in data:
shutil.copy2(row, os.path.join(dst, file_name))
# or if you want to move the file
# shutil.move(row, os.path.join(dst, file_name))
