Let's study Python

Use Python’s glob module for efficient file manipulation and searching!

# Python Glob Usage

## Introduction
Python `glob` module is used to retrieve files/pathnames matching a specified pattern. It is a powerful tool for file manipulation and searching. In this guide, we will explore the various ways `glob` can be used in Python.

## Basic Usage
To use `glob`, you first need to import the module as follows:
“`python
import glob
“`

### Example 1: List all files in a directory
“`python
files = glob.glob(‘/path/to/directory/*’)
print(files)
“`
This will list all files in the specified directory.

### Example 2: List all files with a specific extension
“`python
files = glob.glob(‘/path/to/directory/*.txt’)
print(files)
“`
This will list all files with a `.txt` extension in the specified directory.

## Wildcard Characters
`glob` supports wildcard characters to match patterns in filenames. Here are some commonly used wildcard characters:

– `*` – Matches zero or more characters.
– `?` – Matches a single character.
– `[]` – Matches any one of the enclosed characters.
– `{}` – Matches any one of the comma-separated patterns.

### Example 3: Using Wildcards
“`python
# Match all files starting with ‘file’ and ending with ‘.txt’
files = glob.glob(‘/path/to/directory/file*.txt’)

# Match all files with names ‘file1.txt’, ‘file2.txt’, or ‘file3.txt’
files = glob.glob(‘/path/to/directory/file[123].txt’)

# Match all files with names ‘file01.txt’, ‘file02.txt’, or ‘file03.txt’
files = glob.glob(‘/path/to/directory/file{01,02,03}.txt’)
“`

## Recursive Search
You can perform a recursive search using the `**` wildcard to match any number of directories.
“`python
files = glob.glob(‘/path/to/directory/**/*.txt’, recursive=True)
“`
This will search for all `.txt` files in any subdirectories of the specified directory.

## Conclusion
Python `glob` module is a powerful tool for file manipulation and searching. It provides a convenient way to work with files based on patterns. Experiment with the examples provided to get a better understanding of how `glob` can be used in your Python projects.
