Export list from python to csv file12/5/2023 ![]() ![]() This data can then be read by other services in downstream. While working on any application, it is often a requirement that you would need to export your data from the python application to a data store such as a database or a flat-file. Once you have installed the library, you can check the version that has been installed by running the command below.įigure 2 – Checking the version of the library Exporting data from Python using Pandas ![]() The only dependency is that you must have a version of python running on your machine prior to installing the library. It is covered under the BSD license, so you can use it for free. You can install it on your machine by running the command below. Personally, I love using the library due to the ease of use and the great documentation that is available online. Pandas is one of the most popular libraries used for the purpose of data analysis. In my previous article Getting started with Pandas in Python, I have explained in detail how to get started with analyzing data in python. hr_df2.to_csv('hr.In this article, I am going to discuss the various ways in which we can use Pandas in python to export data to a database table or a file. Note: You can use the following snippet to write your lists without the header when exporting the Pandas DataFrame. Hr_df2 = pd.DataFrame(hr_dict, columns = ) Hr_dict = dict (office = my_list, employees = my_list) Here’s an alternative method, replace the lower part of the code in the section above with this snippet: Method 2: using a dictionary to create the DataFrame # Transpose the data and add column names We first create a Pandas DataFrame from our data, and then export the data to a csv file located in our filesystem Method 1: list of lists to DataFrame # import the Pandas library into your development workspace Json.dump(my_dicts, my_file) Python lists to csv with PandasĪlthough the Python standard library provides useful methods to write list of objects to csv files, the Pandas 3rd party library provides some very elegant methods to accomplish this task. With open('my_dict.txt', 'w') as my_file: dict1 = dict (Atlanta = 100, Boston = 120) We’ll use the json module to transfer the dictionary list. Here’s the output: Export list of dictionaries to a file My_file.write("\n".format(offices,employees)) With open('my_file.csv', 'w') as my_file: ![]() We’ll now use the zip function to stitch the two lists, and then import them as needed into the csv file. ![]() One list has offices and the second has the corresponding number of employees. We would like now to import multiple lists into the file. Print('File not available') Write multiple lists to a file with Python Here’s the code to use: from pathlib import Path In this example, we’ll first check whether our file exists in the operating system, and then append the list values to the file. Print('File created') Append Python list to text / csv file with open('my_file.csv', 'w') as my_file: We’ll start by creating the new file using the file open method, then loop through the list and write the list elements each in a different line. Offices = Save list to a new text / csv file Import list into a new file (could be txt, csv, json or other formats).In today’s tutorial we’ll learn to import Python lists into text files. ![]()
