# __future__ module

`__future__` import statement in simpler terms.

In Python, there are different versions with different features. The `__future__` module allows you to use features from newer versions of Python in an older version.

`from __future__ import print_function` : It tells the Python interpreter that we want to use a feature called "print\_function" from a newer version of Python, even if we're running an older version.

In older versions of Python, the `print` statement was used like this: `print "Hello, world!"`. But in newer versions, it's used like a function: `print("Hello, world!")`.

By using `from __future__ import print_function`, we're telling Python to treat the `print` statement like a function even in older versions. This way, we can write code that works in both older and newer versions of Python without any issues.

So, in simple terms, `__future__` is like a special tool that allows us to use features from newer versions of Python in older versions. It helps make our code more compatible and flexible.

Here's an example that demonstrates the use of the `__future__` module to enable the `print()` function in an older version of Python:

```python
from __future__ import print_function

# Now we can use the print() function
print("Hello, world!")
```

In older versions of Python (e.g., Python 2.x), the `print` statement was used without parentheses, like this: `print "Hello, world!"`. However, in newer versions (e.g., Python 3.x), the `print()` function is used with parentheses, like this: `print("Hello, world!")`.

By including `from __future__ import print_function` at the beginning of the code, we can use the `print()` function syntax even if we're running an older version of Python. This allows the code to be compatible with both older and newer versions of Python.

So, by using `__future__`, we can write code that works across different versions of Python, ensuring better compatibility and easier migration to newer versions when needed.
