In which countries were the clients located who purchased software from the company?

To determine which countries clients who purchased software from the company are located in, sales and registration data are usually analyzed. This may include:

• Client addresses or IP addresses
• Information from payment systems
• CRM data

For example, if you have a database with orders, you can perform a query that groups clients by country:

import pandas as pd

# Suppose we have a DataFrame with orders
orders = pd.DataFrame({
    'client_id': [1, 2, 3, 4],
    'country': ['Russia', 'USA', 'Germany', 'Russia'],
    'product': ['SW1', 'SW2', 'SW1', 'SW3']
})

countries = orders['country'].unique()
print(f"Clients from countries: {countries}")

As a result, you will get a list of countries where your clients are located.
