# How to import modules from string in Python?

In Python, you can use the `import` statement to import a module or package into your code. However, sometimes you may want to dynamically import a module or package from a string, rather than hard coding the module or package name. In this article, we'll explore how to import modules from string in Python using the `importlib` module.

The `importlib` module provides a number of functions for interacting with the import system, including the `import_module` function, which can be used to import a module from a string. To use the `import_module` function, you need to pass it the name of the module as a string, and it will return the module object.

For example, to import the `math` module from a string, you can use the following code:

```python
import importlib

module_name = 'math'
module = importlib.import_module(module_name)
```

Once you have the module object, you can use it like any other module, accessing its attributes and functions using the dot notation. For example, to use the `pi` constant from the `math` module, you can use the following code:

```python
import importlib

module_name = 'math'
module = importlib.import_module(module_name)

print(module.pi)  # 3.141592653589793
```

You can also use the `import_module` function to import submodules or subpackages from a string. To do this, you simply need to include the submodule or subpackage name in the string, separated by a dot. For example, to import the `urllib.parse` module from a string, you can use the following code:

```python
import importlib

module_name = 'urllib.parse'
module = importlib.import_module(module_name)
```

In addition to the `import_module` function, the `importlib` module also provides the `import_from_string` function, which allows you to import a module or object from a string containing the fully qualified name of the module or object. For example, to import the `Decimal` class from the `decimal` module from a string, you can use the following code:

```python
import importlib

module_name = 'decimal.Decimal'
module = importlib.import_from_string(module_name)

decimal = module('3.14')
print(decimal)  # 3.14
```

In conclusion, the `importlib` module provides a number of functions for importing modules and objects from string in Python. By using these functions, you can dynamically import modules or objects
