Need help with a code.

Question

Import random
List=[2,3,4,5,6,7,8,9,10,"A","J","Q","K"]
a=random.choice(list)
b=random.choice(list)
c=random.choice(list)
d=random.choice(list)
e=random.choice(list)
f=random.choice(list)
g=random.choice(list)

on_table=[a,b,c,d,e,f,g,]

**How to count the number of duplicates(pairs) from the on_table list?**
For example if a=4 and d=4 to show 1 pair or if a=5, c=4 , d=5 and g=4 to show 2 pairs.
I need an example and a explication(detailed or not).

Answer 1

Ok. You can try use set.

Set is and i quote "is an unordered collection with no duplicate elements. " --Python3 documentation

Here one example

Answer 2

That is exactly what I needed! Thank you! 😘

Answer 3

just to be sure. Do you only want the quantity of duplicates?

Edit: Or Do you want to know who is the pair of duplicates and total quantity.

Answer 4

Only the quantity of duplicates.

Answer 5

def duplicates(on_table):
counter = []
for card in on_table:
if on_table.count(card) > 1 and card not in counter:
counter.append(card)
return len(counter)
