file in directory python code example

Example 1: get directory of file python

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

Example 2: python script to read all file names in a folder

import os

def get_filepaths(directory):
    """
    This function will generate the file names in a directory 
    tree by walking the tree either top-down or bottom-up. For each 
    directory in the tree rooted at directory top (including top itself), 
    it yields a 3-tuple (dirpath, dirnames, filenames).
    """
    file_paths = []  # List which will store all of the full filepaths.

    # Walk the tree.
    for root, directories, files in os.walk(directory):
        for filename in files:
            # Join the two strings in order to form the full filepath.
            filepath = os.path.join(root, filename)
            file_paths.append(filepath)  # Add it to the list.

    return file_paths  # Self-explanatory.

# Run the above function and store its results in a variable.   
full_file_paths = get_filepaths("/Users/johnny/Desktop/TEST")

Example 3: list files python

import glob
files=glob.glob(given_path)

Example 4: open file in python directory

path = 'C:\\Users\\Username\\Path\\To\\File'
file=open(path, "r")
