Note, classic AMIGAs and derivatives only reach # Python version 2.4.6. AROS goes to version 2.5.2. # Python versions checked against, 1.4.0, 2.0.1, 2.4.2, 2.5.2, 2.6.1 # 2.6.6, 2.7.2, 3.0.1, 3.1.3 and 3.2.2. # # Original copyright, (C)2011, B.Walker, G0LCU.

These print two newlines. print("") print('') # These are a simple basic "ECHO sometext" command. print("This method can be used thoughout as a basic ECHO to the screen.") print('This method can be used thoughout as a basic ECHO to the screen.') # Now a print statement that uses a variable called "texttest". # The bell character assumes that the audio is enabled in all the # platforms above, otherwise it is ignored... texttest="\n\nSometext to print to the screen...\a\b\b Overwrite two of the full stops." print(texttest) texttest='Single quotes with escape character.\rMaybe the start of this line will be overwritten, see the code... ;o)' print(texttest) # =================================================================== # Regular expressions DO NOT work nor print statements/functions with # variables inside. # There will be much more to come. # Enjoy finding simple solutions to often very difficult problems.
