Batch Renaming of Files in a Directory
...
Such renaming is quite easy, for example with os and glob modules:
import glob, os
def rename(dir, pattern, titlePattern):
for pathAndFilename in glob.iglob(os.path.join(dir, pattern)):
title, ext = os.path.splitext(os.path.basename(pathAndFilename))
...
How do I check whether a file exists without exceptions?
...open it.
If you're not planning to open the file immediately, you can use os.path.isfile
Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.
import os.path
os.path.isfile(fname)
if you need to be sure it...
Use 'import module' or 'from module import'?
...ur use of it. Here are some points to help you decide.
import module
Pros:
Less maintenance of your import statements. Don't need to add any additional imports to start using another item from the module
Cons:
Typing module.foo in your code can be tedious and redundant (tedium can be minimi...
How do I copy an entire directory of files into an existing directory using Python?
...standard shutil.copytree seems arbitrary and annoying. Workaround:
import os, shutil
def copytree(src, dst, symlinks=False, ignore=None):
for item in os.listdir(src):
s = os.path.join(src, item)
d = os.path.join(dst, item)
if os.path.isdir(s):
shutil.copytree...
Implement touch using Python?
...han the other solutions. (The with keyword is new in Python 2.5.)
import os
def touch(fname, times=None):
with open(fname, 'a'):
os.utime(fname, times)
Roughly equivalent to this.
import os
def touch(fname, times=None):
fhandle = open(fname, 'a')
try:
os.utime(fname,...

How to get all of the immediate subdirectories in Python
...;dr:
Always use scandir:
list_subfolders_with_paths = [f.path for f in os.scandir(path) if f.is_dir()]
Bonus: With scandir you can also simply only get folder names by using f.name instead of f.path.
This (as well as all other functions below) will not use natural sorting. This means results w...

We are working with a code repository which is deployed to both Windows and Linux - sometimes in different directories. How should one of the modules inside the project refer to one of the non-Python resources in the project (CSV files, etc.)?
