+title: "Quick Python: List Files Recursively"

+
+In order to add website files into a Flask application using setuptools, I needed to recurse down several directories and grab HTML and CSS files.
+
+This Python tip will show you how to get a list of files recursively. 
+
+First in order to solve this problem, we're going to recursively get a list of directories.
+
+```python
+from glob import glob
+directories = glob('/path/to/directory/**/', recursive=True)
+```
+
+Now we will go in each directory and grab the files, 
+
+```python
+data_files = []
+for directory in directories:
+    data_files += list(filter(lambda x: x + '/'  not in directories, glob(directory + '*')))
+```
+
+For setuptools, you would want the `data_files` variable to be a list of tuples with module names and the files associated with them.
+
+Complete script:
+
+```python
+data_files = []
+directories = glob('path/to/files/**/', recursive=True)
+for directory in directories:
+    files = list(filter(lambda x: x + '/' not in directories, glob(directory + "*")))
+    data_files.append((directory, files))
+```
+For setuptools don't forget to `include_package_data`!
