You can write CSV files in Python using the built-in csv module, either from lists or dictionaries, and customize delimiters, quoting, and escape characters as needed.
Method 1: Using csv.writer() with Lists
Import the csv module.
Open the target CSV file in write mode with newline='' to avoid extra blank lines.
Create a writer object using csv.writer(file_object).
Use writer.writerow() to write a single row or writer.writerows() for multiple rows.
Close the file after writing.
Method 2: Using csv.DictWriter() with Dictionaries
Import the csv module.
Open the target CSV file in write mode with newline=''.
Define a list of field names for the CSV header.
Create a csv.DictWriter(file_object, fieldnames=fieldnames) object.
Call writeheader() to write the header row.
Use writerow() or writerows() to write dictionary data.
Close the file after writing.
Method 3: Writing with Custom Delimiters or Quoting
