Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Reading and Writing CSV Files Let’s face it: you need to get information into and out of your programs through more than just the keyboard and console. Exchanging information through text files is a common way to share info between programs. One of the most popular formats for exchanging data is the CSV format. But how do you use it? Let’s get one thing clear: you don’t have to (and you won’t) build your own CSV parser from scratch. There are several perfectly acceptable libraries you can use. The Python csv library will work for most cases. If your work requires lots of data or numerical analysis, the pandas library has CSV parsing capabilities as well, which should handle the rest. In this article, you’ll learn how to read, process, and parse CSV from text files using Python. You’ll see how CSV files work, learn the all-important csv library built into Python, and see how CSV parsing works using the pandas library. So let’s get started! Take the Quiz: Test your knowledge with our interactive “Reading and Writing CSV Files in Python” quiz. Upon completion you will receive a score so you can track your learning progress over time: What Is a CSV File? A CSV file (Comma Separated Values file) is a type of plain text file that uses specific structuring to arrange tabular data. Because it’s a plain text file, it can conta...

Reading files is a necessary task in any programming language. Whether it’s a database file, image, or chat log, having the ability to read and write files greatly enhances what we can with Python. Before we can create an automated audiobook reader or website, we’ll need to master the basics. After all, no one ever ran before they crawled. To complicate matters, Python offers several solutions for reading files. We’re going to cover the most common procedures for reading files line by line in Python. Once you’ve tackled the basics of reading files in Python, you’ll be better prepared for the challenges that lie ahead. You’ll be happy to learn that Python provides several functions for reading, writing, and creating files. These functions simplify file management by handling some of the work for us, behind the scenes. We can use many of these Python functions to read a file line by line. Read a File Line by Line with the readlines() Method Our first approach to reading a file in Python will be the path of least resistance: the readlines() method. This method will open a file and split its contents into separate lines. This method also returns a list of all the lines in the file. We can use readlines() to quickly read an entire file. For example, let’s say we have a file containing basic information about employees at our company. We need to read this file and do something with the data. employees.txt Name: Marcus Gaye Age: 25 Occupation: Web Developer Name: Sally Rain age: ...

Python has a set of methods available for the file object. Method Description Closes the file detach() Returns the separated raw stream from the buffer Returns a number that represents the stream, from the operating system's perspective Flushes the internal buffer Returns whether the file stream is interactive or not Returns the file content Returns whether the file stream can be read or not Returns one line from the file Returns a list of lines from the file Change the file position Returns whether the file allows us to change the file position Returns the current file position Resizes the file to a specified size Returns whether the file can be written to or not Writes the specified string to the file Writes a list of strings to the file Learn more about the file object in our

Python offers programmers six access modes to files, and in this article, we’ll show you the code needed to create, read, close, and write files in Python. You’ll also learn about the various file methods every Python programmer needs to be aware of. In this post, we'll cover: • • • • Let's get started. Files are data or information that exist in the computer’s storage devices. These units of information are used to permanently keep data on a hard disk. By using files, we can keep data for future use. As a computer user, you certainly know about music files, video files, and text files. Well, Python allows you to manipulate these files. What is file handling in Python? Having files is not enough — we need to be able to manipulate them either by opening, closing, writing, or deleting them. File handling in Python is the process of using Python to carry out one of six operations on files: • Read Only • Read and Write • Write Only • Write and Read • Append Only • Append and Read In this article, we’ll show you how to manipulate files using Python file-handling methods. How to Use File Handling in Python In this section, we’ll show you how to use Python to carry out several operations on a file. How to Open a File in Python Python has made opening files quite straightforward because the language has a built-in open function. Reading and writing files is also quite easy in Python. However, before starting any of that, you must first open the files in the right mode. There are t...
