When you’re done working with your project file and about to step away, do a final save, close the application, and back up the latest version—just to be safe. Yes, there are costs associated with these options, but it’s usually much less than the cost of losing your work, which can represent many, many hours of development time. If you work in an office setting, check to see if the IT department has a backup system already in place. If so, ask about the policy, and then consider making your own backups as well, as an extra precaution.

This is particularly important in relating separate rows, since DEFLATE has no understanding that an image is a 2D entity, and instead just sees the image data as a stream of bytes. With indexed color images, the palette always stores trichromatic colors at a depth of 8 bits per channel . The palette must contain entries for all the pixel values present in the image. Other image attributes that can be stored in PNG files include gamma values, background color, and textual metadata information. PNG also supports color management through the inclusion of ICC color space profiles.

Excel can save a spreadsheet to a CSV file with a few mouse clicks, but if you had to convert hundreds of Excel files to CSVs, it would take hours of clicking. Using the openpyxl module from Chapter 12, write a program that reads all the Excel files in the current working directory and outputs them as CSV files. After you import the csv module and make a Reader object from the CSV file, you can loop through the rows in the Reader object. Each row is a list of values, with each value representing a cell.

If you are planning to move your data between platforms, export and import it from one interface to another, you might be better off with the CSV file format. The difference between CSV and XLS is quite simple. The CSV format is a plain text file type, where you separate values by commas. However, XLS is a quite different kind of solution, known as “binary file format”. This holds information about all the worksheets in your file, including the formatting and content options. The easiest way to create an CSV file is to start with your spreadsheet in something like Microsoft Excel. When you’re done editing your content, instead of saving it as a plain text file, you simply save the file as a CSV, which means you can separate each newline with a comma.
