LIST IN 2D

 LIST IN 2D 

Tables are two-dimensional data structures where we can store data both vertically and horizontally. 


Eg:

my2DList = [ ["Johnny", 21, "Mac"],
             ["Sian", 19, "PC"],
             ["Gethin", 17, "PC"] ]


print(my2DList[2][2])

 

Editing a 2D List 


We can edit values in a 2D list in the same way as variables and 1D lists. You just need to change the value to the new row and column index numbers

Eg: 

my2DList = [ ["Johnny", 21, "Mac"],
             ["Sian", 19, "PC"],
             ["Gethin", 17, "PC"] ]
my2DList[1][2] = "Linux"

print(my2DList[1])

ALL ABOUT WHILE LOOP

 WHILE LOOP  A  while  loop allows your code to repeat itself based on a condition you set.   EXAMPLE : counter = 0 while counter < 10:   print(counter)   counter +=1 Infinite Loop  You have to be  really  careful that you don't accidentally invoke an infinite loop! This is where the computer will loop code until the end of time. Without a break. Forever.  This is just saying "count to 10 by 1 each time." to make the loop end. Don't forget, if your  condition  is a  >  then you might need to  -= . This will subtract from the variable instead of adding to it.   EXAMPLE : counter = 0 while counter < 10:   print(counter)    counter += 1

Automate! Automate!

 Making this customizable 👉So how about making our search user customizable? In the code below, I have: Asked the user to input an artist (line 14) Tidied up their input (line 15) formatted the search URL as an fString that includes the artist (line 19) Here's tAutomate! Automate! We are so close. I can taste it, folks! Massive kudos on getting this far! Today's lesson, however, will work best if you have one of Replit's paid for features (hacker plan or cycles). Free plan Repls 'fall asleep' after a while. Automation kinda relies on the Repl being always on. If you have hacker plan or you've bought some cycles, then you can enable always on in the drop down menu that appears when you click your Repl name (top left).he code: This is important because when our repl is always running, it can keep track of time and schedule events. 👉 I've set up a simple schedule that prints out a clock emoji every couple of seconds. It works like this: Import schedule librar...
