/05_Python_Files

Python too supports file handling and allows users to handle files i.e., to read and write files, along with many other file handling options, to operate on files. The concept of file handling has stretched over various other languages, but the implementation is either complicated or lengthy, but like other concepts of Python, this concept here is also easy and short. Python treats files differently as text or binary and this is important.

Introduction πŸ‘‹

Python file I/O (a.k.a File handling) is one of the essential topics for programmers and automation testers. It is required to work with files for either writing to a file or read data from it.

Also, if you are not already aware, I/O operations are the costliest operations where a program can stumble. Hence, you should be quite careful while implementing file handling for reporting or any other purpose. Optimizing a single file operation can help you produce a high-performing application or a robust solution for automated software testing.

In Python, file processing takes place in the following order.

  • Open a file that returns a filehandle.
  • Use the handle to perform read or write action.
  • Close the filehandle.

Before you do a read or write operation to a file in Python, you need to open it first. And as the read/write transaction completes, you should close it to free the resources tied with the file.

    Download ZIP

  3. Extract the ZIP and open it. Unfortunately I don't have any more specific instructions because how exactly this is done depends on which operating system you run.

  4. Launch ipython notebook from the folder which contains the notebooks. Open each one of them

    Cell > All Output > Clear

This will clear all the outputs and now you can understand each statement and learn interactively.

If you have git and you know how to use it, you can also clone the repository instead of downloading a zip and extracting it. An advantage with doing it this way is that you don't need to download the whole tutorial again to get the latest version of it, all you need to do is to pull with git and run ipython notebook again.
