2D list with while true loop

Loops, append() and break

Eg:

list_of_question = []
while True:
name = input("what is your name")
age = input("what is your age " )
platfrom = input("which os do u use ")
row = [name, age, platfrom]
list_of_question.append(row)
exit = input("Exit? y/n ")
if (exit.strip().lower()[0] == "y"):
break
print(list_of_question)

Add or Remove?

ask for a name on the list (make sure it is spelled correctly)
extract each row, one at a time, from the list
check the row to see if it contains the name
if the name is in the row, use the .remove() method to remove the whole row, not just the name.

Eg:

listOfShame = []

while True:
menu = input("Add or Remove?")

if(menu.strip().lower()[0]=="a"):

name = input("What is your name? ")
age = input("What is your age? ")
pref = input("What is your computer platform? ")

row = [name, age, pref]

listOfShame.append(row)


else:
name = input("What is the name of the record to delete?")
for row in listOfShame:

if name in row:
listOfShame.remove(row)

print(listOfShame)

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...

WHAT IS Nesting

WHAT IS Nesting Nesting is where we put an if statement within an if statement using the power of indenting. The second if statement within the first if statement must be indented and its print statement needs to be indented one more time. EXAMPLE:
