Python DictWriter writing UTF-8 encoded CSV files

Python DictWriter writing UTF-8 encoded CSV files

When using Python's csv.DictWriter to write UTF-8 encoded CSV files, you can achieve this by specifying the encoding parameter when opening the output file. Here's how you can do it:

import csv # Define your data as a list of dictionaries data = [ {'name': 'Alice', 'age': 30}, {'name': 'Bob', 'age': 25}, {'name': 'Charlie', 'age': 35} ] # Specify the file name and encoding (UTF-8) file_name = 'output.csv' encoding = 'utf-8' # Define the CSV header fieldnames = ['name', 'age'] # Open the CSV file in write mode with UTF-8 encoding with open(file_name, mode='w', newline='', encoding=encoding) as file: # Create a DictWriter object writer = csv.DictWriter(file, fieldnames=fieldnames) # Write the header row writer.writeheader() # Write the data rows writer.writerows(data) print(f'CSV file "{file_name}" has been written with UTF-8 encoding.')

In this code:

  1. We define our data as a list of dictionaries.

  2. We specify the file name (file_name) and the encoding (encoding) as 'utf-8'.

  3. We define the CSV header using the fieldnames list.

  4. We open the CSV file in write mode ('w') with UTF-8 encoding ('utf-8') using the open() function.

  5. We create a csv.DictWriter object, passing in the file object and the fieldnames.

  6. We write the header row using writer.writeheader().

  7. We write the data rows using writer.writerows(data).

The resulting CSV file (output.csv in this example) will be encoded in UTF-8. You can open it with any text editor or spreadsheet software that supports UTF-8 encoding to view the data correctly.
