Python scripts are usually run as a command-line program, from the system command prompt (a.k.a. terminal). Python scripts are created by making Python modules which are meant to be [imported][import] (see making a main function and module vs script). Command-line interface A script or...

#Printing to terminals sometimes fails. For example, #with an encoding of ‘cp1251‘, the above write will #work if written to a stream opened or wrapped by #the codecs module, but fail when writing to a #terminal even when the codepage is set to cp1251. #An extra encoding step see...

Using os.scandir() has the advantage of looking cleaner and being easier to understand than using os.listdir(), even though it is one line of code longer. Calling entry.is_file() on each item in the ScandirIterator returns True if the object is a file. Printing out the names of all ...
Though it is not mandatory it is a good practice to specify Python environment into the script file itself through shebang notation. For this we simply need to include the following line at the starting of the script file. #!/usr/bin/python It simply specifies where is the interpreter requi...
critical ( 'Last message before a program crash!' ) Another really neat trick is that when you use logging, writing messages during exception handling is a whole lot easier. You don’t have to deal with sys.exc_info() and the traceback module merely for printing out the exception message...
