# Creating Python Modules

### Creating module

Create a new file called `mymodule.py` and write the following code.

|   |   |
| - | - |

As you can see we have defined a global variable `foo` and a function `hello()` in our module. Now to use this module in our programs we first need to import it using import statement like this

```
import mymodule
```

Now you can use variable and call functions in the `mymodule.py` using the following code.

|   |   |
| - | - |

**Expected Output:**

|   |   |
| - | - |

Remember you need to specify name of module first to access it's variables and functions, failure to so will result in error.

### Using `from` with `import`

Using import statements imports everything in the module, what if you want to access only specific function or variable? This is where the `from` statement comes, here is how to use it.

|   |   |
| - | - |

**Expected output:**

```
100
```

 **Note:**

In this case you don't need to specify module name to access variables and function.

### dir() method

The `dir()` is an in-built method used to find all attributes (i.e all available classes, functions, variables and constants ) of the object. As we have already discussed everything in python is object, we can use the `dir()` method to find attributes of the module like this:

```
dir(module_name)
```

The `dir()` returns a list of string containing the names of the available attributes.

| - | - |

As you can see besides foo and hello there are additional attributes in the `mymodule`. These are in-built attributes which python provides to all the modules automatically.
