What is the difference between remove() and pop()?
Short answer. remove() deletes by value; pop() deletes by index and returns the item.
What does count() tell you?
How many times a value appears.
Remember
| count: how many times |
| index: first position |
| remove by value, pop by index |
| reverse() flips the list |
Remove or pop? Why two? Remove deletes the first four. Reverse flips it. Count finds one four. Pop removes six. Index finds four at one. Count tells how many. Index gives position. Remove by value, pop by index. Reverse flips.
