Accessing the base name from a given path in Python without considering the file extension

In the world of Python programming, there are several methods to extract a filename without its extension from a file path. This article will explore some of the most efficient and standard techniques available.

Firstly, let's discuss the function. This built-in module can be used to pull out the filename regardless of the platform, and can be used to find the final dot. By using , you can return the filename without the extension.

Another method involves using the function. This splits a string into two parts from the right at the last occurrence of the dot. Index 0 of the list returned by keeps everything before the dot, which is the filename without the extension.

The most efficient Python module for this task is the built-in os.path module. Using method, you can separate the extension and the filename part. The root part returned by is the filename without the extension.

Alternatively, the pathlib module offers a more modern, object-oriented approach. Using will return a Path object, and attribute can be used to get the filename without the extension. This method works uniformly on Windows, macOS, and Linux.

It's important to note that on different operating systems, Python can handle file paths using separators like */ (Linux/macOS) and **\ (Windows). Leading dots (e.g., .txt) are treated as part of the filename, not as an extension.

Lastly, using returns a tuple containing the portion before the last dot, the separator ('.'), and the portion after the last dot. Index 0 of the tuple gives the portion before the last dot, which is the filename without the extension.

In summary, whether you prefer the built-in module, the modern module, or the versatile , Python provides several efficient methods to extract a filename without its extension from a file path.
