# Directory & IO

## Working with Directories

In Python, you can use the `os` module to work with directories (also called "folders"). The `os` module provides functions to perform various operations on directories.

Here are a few examples of common tasks you might perform with the `os` module:

**Creating a Directory**

To create a new directory, you can use the `os.mkdir()` function. This function takes a single argument, which is the name of the directory you want to create.

```python
import os

# Create a new directory called "newdir"
os.mkdir("emmanuella")
```

**Changing the Current Working Directory**

To change the current working directory, you can use the `os.chdir()` function. This function takes a single argument, which is the path of the directory you want to change to.

```python
import os

# Change the current working directory to "newdir"
os.chdir("emmanuella")
```

**Listing the Contents of a Directory**

To list the contents of a directory, you can use the `os.listdir()` function. This function takes a single argument, which is the path of the directory you want to list the contents of. It returns a list of the names of the files and directories in that directory.

```python
import os

# List the contents of the current working directory
contents = os.listdir()
print(contents)
```

**Checking if a Path is a Directory**

To check if a given path is a directory, you can use the `os.path.isdir()` function. This function takes a single argument, which is the path you want to check. It returns `True` if the path is a directory, and `False` if it is not.

```python
import os

# Check if the current working directory is a directory
is_dir = os.path.isdir(".")
print(is_dir)
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://pythonforstarters.solomonmarvel.com/directory-and-io.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
