In this article, we’ll look at how to iterate over files in a given directory with Python.

How to iterate over files in a given directory with Python?

To iterate over files in a given directory with Python, we can use the os.listdir method.

For instance, we write

import os

directory = os.fsencode(directory_in_str)

for file in os.listdir(directory):
    filename = os.fsdecode(file)
    if filename.endswith('.asm') or filename.endswith('.py'):
        print(os.path.join(directory, filename))

to call os.list to list the items in the directory.

Then we call os.path.join in the loop to join the directory and filename into the full path of the file path being iterated through.

Conclusion

To iterate over files in a given directory with Python, we can use the os.listdir method.
