![]() ![]() Being able to read data files with Python allows you to restore an application to a useful state when you rerun it at a later time. Python excels at reading from and saving to files. The comma character delimiter indicates the boundary between data values. Each line of text represents a row of data, and each comma-separated value is a field within that row. Because they don’t have to use fixed field widths, flat files often use other structures to make it possible for a program to parse text.įor example, comma-separated value (CSV) files are lines of plain text in which the comma character separates the data elements. Flat files contain human-readable characters and are very useful for creating and reading data. Using Flat Files for Data StorageĪ flat file is a file containing data with no internal hierarchy and usually no references to external files. You can get all of the code and data you’ll see in this tutorial by clicking on the link below:ĭownload the sample code: Click here to get the code you’ll use to learn about data management with SQLite and SQLAlchemy in this tutorial. SQLAlchemy to work with data as Python objects.SQL to improve access to persistent data.In this tutorial, you’ll learn how to use: ![]() Below, you’ll explore using SQL databases and flat files for data storage and manipulation and learn how to decide which approach is right for your program. Flat files are often human-readable text files-though they can also be binary data-with a structure that can be parsed by a computer program. You can achieve similar results using flat files in any number of formats, including CSV, JSON, XML, and even custom formats. Python, SQLite, and SQLAlchemy give your programs database functionality, allowing you to store data in a single file without the need for a database server. Watch it together with the written tutorial to deepen your understanding: SQLite and SQLAlchemy in Python: Moving Your Data Beyond Flat FilesĪll programs process data in one form or another, and many need to be able to save and retrieve that data from one invocation to the next.
