If the battery is @ a full charge, unplug and allow it to gradually lose power before re-plugging for long periods of time (Some electronics automatically shut off to prevent overcharge. Check the specs of your devices if this feature is included. If you can’t find the feature it’s probably not included).

But the last one is excluded. Examples: print (word[2])     ==> t print (word[-1])     ==> G print (word[2:5])     ==> tho print(word[1:-1])  ==> ython and Mr. Function = Methods message.upper()                   # to convert to uppercase message...
