Program Code – Python to CSV: Exporting Data to CSV Files
# Importing required modules
import csv
import os
# Define a function to export data to a CSV file
def export_to_csv(data, filename):
# Check if the data is a list of dictionaries
if isinstance(data, list) and all(isinstance(item, dict) for item in data):
# Open the file with the context manager to ensure it's properly closed after
with open(filename, 'w', newline='') as csvfile:
# Try to infer the header from the keys of the first dictionary
header = data[0].keys()
writer = csv.DictWriter(csvfile, fieldnames=header)
# Write the header
writer.writeheader()
# Write the rows
for row in data:
writer.writerow(row)
print(f'File {filename} has been created successfully.')
else:
print('Data format is not supported. Please provide a list of dictionaries.')
# Example data to write to CSV
data_to_export = [
{'name': 'Alice', 'age': 25, 'job': 'Data Scientist'},
{'name': 'Bob', 'age': 30, 'job': 'Developer'},
{'name': 'Charlie', 'age': 35, 'job': 'Designer'}
]
# Filepath to save the CSV file
csv_filename = 'data.csv'
# Export the data
export_to_csv(data_to_export, csv_filename)
Code Output:
The expected console output after running the above script would be:
File data.csv has been created successfully.
Code Explanation:
The above code snippet is written in Python and it illustrates how to export a list of dictionaries to a CSV file. First off, we import the necessary csv and os modules. The csv module includes the DictWriter class which is ideal for writing CSV files directly from a dictionary where keys act as column headers and values as the row.
The heart of the script is the export_to_csv function. This thing checks that the data passed to it is a list of dictionaries. That’s a sweet format because each dictionary represents a row in the CSV, with key-value pairs that correspond to column names and cell data.
We’re being smart with resources by using the context manager with to open a file; it takes care of all that opening and closing file business. We create an instance of DictWriter by passing the file object and the headers (extracted from the keys of the first dictionary). Just to make it shine, we write the header with writeheader() before we even think about looping through the data list to write each row with writerow().
For demo purposes, there’s some dummy data created in data_to_export, which is a charming list of dictionaries, each with the name, age, and job of some imaginary friends. The filename for the CSV is set to data.csv, and finally, we call export_to_csv with the data and filename. When you run the script, it checks everything’s hunky-dory, writes the CSV file, and prints a success message to the console.
And just like that, poof! You’ll have a CSV file named data.csv sitting pretty in the same directory as your script. It’s pretty slick, right?
