in this tutorial, we will explore how to import csv (comma-separated values) files in python. csv files are a popular way to store tabular data, and python provides several libraries to work with them. we'll primarily focus on the built-in csv module for simplicity and versatility.
before we begin, make sure you have python installed on your system. you can download it from the official python website.
python's standard library includes the csv module, which provides functions to read and write csv files. to use it, import the csv module in your python script:
before we proceed, let's assume we have a csv file named data.csv with the following content:
here's how you can read the contents of data.csv using the csv.reader() function:
the csv.reader() function reads each row from the csv file and returns it as a list of strings.
you can also write data to a csv file using the csv.writer() function. here's an example:
in this example, we first define the data as a list of lists. each inner list represents a row in the csv file. then, we use csv.writer() to write the data to a new csv file named output.csv.
in this tutorial, we've covered the basics of importing and reading csv files in python using the csv module. you can now efficiently work with csv data in your python scripts, both for reading and writing purposes. remember to handle exceptions and edge cases appropriately, especially when dealing with real-world data.
