# Python Glob Module

The `glob` module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, although results are returned in arbitrary order.

## Importing the Module

```python
import glob
```

## Basic Usage

The `glob.glob()` function returns a list of files that match the pattern.

```python
import glob

# Find all .py files in the current directory
files = glob.glob('*.py')
print(files)
```

## Wildcards

*   `*`: Matches zero or more characters.
*   `?`: Matches exactly one character.
*   `[]`: Matches a range of characters.

```python
import glob

# Find files starting with 'file' and ending with .txt
print(glob.glob('file*.txt'))

# Find files with a single character name
print(glob.glob('?.txt'))

# Find files with a number range
print(glob.glob('[0-9].txt'))
```

## Recursive Search

If `recursive` is true, the pattern `**` will match any files and zero or more directories, subdirectories and symbolic links to directories.

```python
import glob

# Find all .txt files in current directory and subdirectories
files = glob.glob('**/*.txt', recursive=True)
print(files)
```

## Iterators

`glob.iglob()` returns an iterator which yields the same values as `glob()` without actually storing them all simultaneously.

```python
import glob

for file in glob.iglob('**/*.py', recursive=True):
    print(file)
```
