>> c = C ( 1 , 2 , 4 ) The instances of class C … Then you'll polish your work, turning it into a more professional command line tool, by including data validation and support to use them with command line arguments. If PyCharm detects no Python on your machine, it provides two options: to download the latest Python versions from python.org or to specify a path to the Python executable (in case of non-standard installation). Recall that, besides validating the interactive input, you'll also validate the command line argument in this case. When configuring the base interpreter, you need to specify the path to the Python executable. In this case, you are going to need to validate two inputs: the file name and the angle. That's why you're using some structures twice: You can see that the while loop used to validate the image file name is identical to the one used in the previous example. The best way to learn Python is by practicing examples. Note that the validation block for the image file name is identical while the ones for validating the width and the height are similar to the one used to validate the angle in the previous example.
