如何在特定驱动器的所有子目录中创建文件？

Question

I'd like to create a text file (with contents inside) and have that file copies/created in every subdirectory (folder) on a specific drive, say D with Python. Preferably using pre-installed python libraries and not needing to pip install anything.

So the Python 3 script runs from drive C, creates a text file with text inside it and pastes that text file once in every folder on Drive D. I need this to work on Windows.

create("file.txt", contents "example text")
copy("file.txt" to "D:\*")

Example output

Copied file.txt to D:\
Copied file.txt to D:\folder example
Copied file.txt to D:\folder example\subfolder example
Copied file.txt to D:\another folder

Answer 1

You can use os.walk to get all directories. For example, try

import os
filename = "myfile.txt"
filetext = "mytext"
directories = os.walk("D:")
for directory in directories:
    with open(directory[0]+"\\"+filename, "w") as file:
        file.write(filetext)

This will write filetext in a file myfile.txt in every directory in D: .

Edit: You might want to add a try statement to this, if you don't have permissions to a certain directory

Answer 2

It is called recursive directory traversal

Hope this hint will help you.

This is the line that interests you.

print((len(path) - 1) * '---', os.path.basename(root))

Answer 3

Like so using OS lib:

from os import listdir
from os.path import isfile

path = "/some/path"

for f in listdir(path):
    if not isfile(path):
        filepath = "{0:s}/dummy.txt".format(path)
        with open(filepath, 'w') as f:
            f.write('Hi there!')

or using glob:

import glob

path = '/some/path/*/'
paths = glob.glob(path)
filename = "dummy.txt"

for path in paths:
    filepath = "{0:s}{1:s}".format(path, filename)
    with open(filepath, 'w') as f: 
        f.write('Hi there!')

Please Note!: Second solluton will work under Linux OS only (because of glob)
