Answer 1

If you are wondering what is set:
It is a set object, which is very similar to a lists, but:
sets can not be indexed or sliced.
sets can not have duplicate values.

We converted the list a to a set using set() function(*1), which automatically removed the duplicate values.

(1*)not just a function, much more.

Answer 2

a little late, but here is my try:

a=[10,20,30,40,30,40,20,45,78,54,10]
print("the list is - ", a)
for i in sorted(list(set(a))):
print(f'Num: {i} is {a.count(i)}')

'''
the list is - [10, 20, 30, 40, 30, 40, 20, 45, 78, 54, 10]
Num: 10 is 2
Num: 20 is 2
Num: 30 is 2
Num: 40 is 2
Num: 45 is 1
Num: 54 is 1
Num: 78 is 1
'''

Answer 3

The easiest method is:
for i in set(a):
print(i, "-", a.count(i))

Answer 4

Do you mean of using break statements when using nested loops?

Answer 5

Oohhh there is a count method ....i totally forggot
