CSV (Comma Separated Values) is a popular file format for storing tabular data. Python provides a built-in module called csv to work with CSV files. In this tutorial, we will explore how to read a CSV file in Python using the csv module.
Make sure you have Python installed on your system. You can download it from python.org. The examples in this tutorial are based on Python 3.
To read a CSV file in Python, follow these steps:
Import the csv module:
Open the CSV file:
Use the open() function to open the CSV file. Specify the file path and the mode ('r' for read).
Create a CSV reader object:
Use the csv.reader class to create a reader object, passing the file object as an argument.
Read the data:
Iterate through the rows of the CSV file using a loop.
Here's a complete example that reads a CSV file and prints its content:
Assume that the CSV file (example.csv) has the following content:
The output of the example code will be:
If your CSV file has a header row (column names), you may want to skip it while processing the data. Here's how you can modify the code to skip the header:
In this modified example, the next(csv_reader) call is used to skip the first row (header) of the CSV file.
Reading CSV files in Python is straightforward with the csv module. The csv.reader class provides a convenient way to iterate through the rows of a CSV file. Remember to handle header rows if your CSV file includes them.
