Python Program to Find All File with .txt Extension Present Inside a Directory

Example 1: Using glob

Output

c.txt
b.txt
a.txt

Using glob module, you can search for files with certain extensions.

• os.chdir("my_dir") sets the current working directory to /my_dir.
• Using a for loop, you can search for files with .txt extension using glob().
• * denotes all files with a given extension.

Example 2: Using os

Output

a.txt
b.txt
c.txt

In this example, we use endswith() method to check the .txt extension.

• Using a for loop, iterate through each file of directory /my_dir.
• Check if the file has extension .txt using endswith().

Using os.walk

Output

c.txt
b.txt
a.txt

This example uses the walk() method of the os module.

• Using a for loop, iterate through each files of my_dir.
• Check if the file has extension .txt using endswith().
