the glob module in python is a powerful tool for working with file paths and directories. it provides a convenient way to search for files that match a specified pattern using wildcards. this tutorial will guide you through the basics of the glob module, along with practical examples to help you understand its usage.
the glob module is part of the python standard library and comes pre-installed with python. its primary purpose is to simplify file and directory path manipulation by using pattern matching. the module uses the wildcard characters * (matches any sequence of characters) and ? (matches any single character) to find files and directories that match a specified pattern.
to use the glob module, you need to import it first:
the glob function is the main entry point for using the module. it returns a list of pathnames that match the specified pattern. here's a basic example:
in example 1, the *.txt pattern is used to match all files with a .txt extension in the current directory. in example 2, the images/*.png pattern matches all .png files in the 'images' directory.
the ** wildcard allows for recursive directory searching. this is useful when you want to search for files not only in the specified directory but also in its subdirectories:
in this example, the **/*.py pattern matches all .py files recursively in the current directory and its subdirectories.
besides * and ?, you can use character ranges with [ ] to match a specific set of characters:
in this example, the pattern file[0-9]* matches files whose names start with 'file' followed by any digit.
the glob module is a versatile tool for working with file paths and directories in python. by using simple patterns, you can easily search for and manipulate files based on your specific needs. this tutorial covered the basic usage of the glob module, including recursive searches and additional wildcard characters. experiment with these examples to gain a deeper understanding of how glob can simplify your file ...
