Since I don’t have direct access to your local files, I’ll provide a that reads, updates, and processes a CSV file with a similar name pattern. This assumes the CSV contains customer data and you want to handle updates (e.g., “atualizado 2” meaning “updated 2” in Portuguese). 🐍 Python script to read and update the CSV import pandas as pd import os File path (adjust as needed) filename = "all customers atualizado 2 arion - all customers.csv" Check if file exists if not os.path.exists(filename): print(f"File not found: {filename}") exit() Read CSV df = pd.read_csv(filename, encoding='utf-8-sig') Display basic info print("✅ File loaded successfully!") print(f"Rows: {df.shape[0]}, Columns: {df.shape[1]}") print("\nFirst 5 rows:") print(df.head())
