How to get filename and extension in Python

To get the filename and extension from a file path in Python, you can use the os.path module from the Python standard library. Specifically, you can use the os.path.splitext() function to split the file path into a tuple containing the filename without the extension and the extension itself.

Here's an example:

import os.path

# The file path
file_path = "example_directory/example.txt"

# Split the file path into a tuple containing the filename without the extension and the extension
file_name_without_extension, file_extension = os.path.splitext(file_path)

# Get the base file name (including the extension)
base_file_name = os.path.basename(file_path)

# Print the filename without the extension, the extension, and the base file name
print("The filename without the extension is:", file_name_without_extension)
print("The file extension is:", file_extension)
print("The base file name is:", base_file_name)

In this example, we have a file path called file_path. We use the os.path.splitext() function to split the file path into a tuple containing the filename without the extension and the extension. Then, we use the os.path.basename() function to get the base file name, which includes the extension. Finally, we print the filename without the extension, the extension, and the base file name.

Please note that the os.path.splitext() function returns the file extension with a leading dot (e.g., ".txt"). If you want the extension without the dot, you can remove it using string slicing:

file_extension = file_extension[1:]  # Remove the leading dot

Extract filename from path in Python:

import os

file_path = '/path/to/example.txt'
filename = os.path.basename(file_path)

print(f"Filename: {filename}")

Using os.path.splitext() for filename and extension in Python:

import os

file_path = '/path/to/example.txt'
filename, extension = os.path.splitext(file_path)

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Get file name without extension in Python:

import os

file_path = '/path/to/example.txt'
filename, _ = os.path.splitext(os.path.basename(file_path))

print(f"Filename without extension: {filename}")

Retrieve file extension using os.path.splitext() in Python:

import os

file_path = '/path/to/example.txt'
_, extension = os.path.splitext(file_path)

print(f"Extension: {extension}")

Python os.path.basename() for extracting filename:

import os

file_path = '/path/to/example.txt'
filename = os.path.basename(file_path)

print(f"Filename: {filename}")

Separate filename and extension with os.path in Python:

import os

file_path = '/path/to/example.txt'
filename = os.path.basename(file_path)
extension = os.path.splitext(filename)[1]

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Splitting file path into filename and extension in Python:

file_path = '/path/to/example.txt'
parts = file_path.rsplit('/', 1)
filename, extension = os.path.splitext(parts[-1])

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Python pathlib.Path() for filename and extension:

from pathlib import Path

file_path = '/path/to/example.txt'
path_obj = Path(file_path)

print(f"Filename: {path_obj.name}")
print(f"Extension: {path_obj.suffix}")

Extract filename and extension with os.path.split() in Python:

import os

file_path = '/path/to/example.txt'
filename, extension = os.path.splitext(os.path.split(file_path)[1])

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Using os.path.splitext() and os.path.basename() together in Python:

import os

file_path = '/path/to/example.txt'
_, filename_with_extension = os.path.split(file_path)
filename, extension = os.path.splitext(filename_with_extension)

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Get filename without extension using os.path.basename() in Python:

import os

file_path = '/path/to/example.txt'
filename = os.path.basename(file_path)
filename_without_extension, _ = os.path.splitext(filename)

print(f"Filename without extension: {filename_without_extension}")

Python rsplit() for filename and extension from path:

file_path = '/path/to/example.txt'
filename, extension = file_path.rsplit('.', 1)

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Extract filename and extension using string slicing in Python:

file_path = '/path/to/example.txt'
last_dot_index = file_path.rfind('.')
filename = file_path[:last_dot_index]
extension = file_path[last_dot_index:]

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Separate filename and extension with regular expressions in Python:

import re

file_path = '/path/to/example.txt'
match = re.match(r'(.+?)(\..+)?$', os.path.basename(file_path))
filename, extension = match.groups()

print(f"Filename: {filename}")
print(f"Extension: {extension}")

Extract file name and extension using pathlib in Python:

from pathlib import Path

file_path = '/path/to/example.txt'
path_obj = Path(file_path)

print(f"Filename: {path_obj.stem}")
print(f"Extension: {path_obj.suffix}")

Retrieve file extension with os.path.splitext() and string methods in Python:

import os

file_path = '/path/to/example.txt'
_, extension_with_dot = os.path.splitext(file_path)
extension = extension_with_dot[1:]

print(f"Extension: {extension}")

Get filename without extension with pathlib in Python:

from pathlib import Path

file_path = '/path/to/example.txt'
path_obj = Path(file_path)

print(f"Filename without extension: {path_obj.stem}")

Splitting file path into directory, filename, and extension in Python:

file_path = '/path/to/example.txt'
directory, filename = os.path.split(file_path)
filename, extension = os.path.splitext(filename)

print(f"Directory: {directory}")
print(f"Filename: {filename}")
print(f"Extension: {extension}")
