How to run given Python script with class, init and main from cmd?

Question

I'm supplid with script.py file with Python contents of which this is psuedo code:

import pandas as pd
import numpy as np

params = {...}

class SomeClass:
    def __init__(self, ab):
        self.ab = ab
        self.de = None

    def main(self):
        self.foo()

    @staticmethod
    def DoSomethingUsefull(abc, params=params):
        abc['x'] = abc['Red Fox'].copy()
        return some_list(abc);
    
    def foo(self):
        self.de = SomeClass.DoSomethingUsefull(self.ab)       
        self.de['de'] = "de"

I cannot change the contents of the file, just use it as is. Eventually I need to execute the script from external (C#) code, currently trying to run from cmd (Python is installed). My question is how to execute from command line? If it's not possible to execute from command line and a wrapper script is needed, what will it look like?
