How to pass a class/module definition into another file
Question: I'm a beginner in OOP Python and I just wanna know this:

This is **file.py** :

    
    
    class Card():
    
        def __init__(self, rank, suit):
            """Initialization method"""
            self.rank = rank
            self.suit = suit
    
        def get_rank(self):
            """Function get_rank returns a rank (value) of the card"""
            return self.rank
    

When I wanna create and pass an object to the function "get_rank" in this
file, I can do this:

    
    
    card1 = Card(10,"Diamond")
    card1.get_rank()
    

But how can I create and pass an object in another file? There is another file
called **test_file.py** , it's a testing file (py.test). So **file.py** is for
code only, **test_file.py** represents parameters (variables and objects)
which are passed to **file.py**. In **test_file.py** is also variable
"expected_result" with a correct result. Then when I use "py.test" (bash), it
shows me, if the result is correct or not.

I understand this non-OOP example: **abs.py** :

`def split_text(text): - code -`

**test_abs.py** :

    
    
    def test():
        text = 'abcdefgh'
    

Please help, thanks for any advice :)


Answer: In your `test_file.py`:

    
    
    from file import Card
    
    ...
    card1 = Card(10, "Diamond")
    # Do something with it
    

By the way, do not name your file file.py: `file` is a built-in function.
