how to find the repeated item of a tuple？ tup=（2，4，5，6，2，3，4，4，7，8，4，3，2） expecting output：4

Answer 1

for i in tup:
if tup.count(i) > 1:
print('REPEATED')

I think this is the shortest solution

Answer 2

print(tup.count(4)) # outputs 4 because there are 4 fours

Answer 3

This is perfect :

Answer 4

@Tobi Yes! I have just started learning python. Will learn every module completely.

Oh! And they does not teach lambda or Linq in C# here. You will need to learn it on the MSDN. Very few programmers use these techniques. So less tutorials out there for advance programming. 😔

Answer 5

@Tobi Wow! There is also lambda expression in python too!! Lambda makes codes much smaller and efficient. I always use lambda expression in C#. 😉

Answer 6

Perhaps use a loop that would find out how many repeats a number has (maybe with an array). Then you can just find the number with the most repeats.

Or use 2 nested loops, one to check number of repeats, one to go through the other loop again to see if there's a larger repeat. (easier method but O(n^2) complexity.)

Edit:
@mary sorry I've never done python so i wouldn't be able to help with writing the actual code.

Answer 7

@Cyrus: Yeah, I love all these concepts from functional programming too. Python has quite a few cool concepts like these, check out the functional programming module in the course, if you like. SoloLearn really did a great job introducing them.

I will definitely look into C#, when the time has come.

Answer 8

This gives you one of the list elements, which are repeated the most. Essentially one line and not to inelegant:

Answer 9

Why 4 and not 2? 2 is also repeated.

Answer 10

@Tobi maybe the question wants the most repeated.

Answer 11

@Rrestoring faith
it's too complicated for me……

Answer 12

okay，thank you all

Answer 13

#This finds the repeated items in a tuple....

tup= (1,2,3,4,4,5,5,12,12,12,12,1,3,2,4, "my", "my", "hi", "hi", "hello")
rep=[]
for i in tup:
if tup.count(i)>1:
rep.append(i)
else:
continue
for x in rep:
while rep.count(x)>1:
rep.remove(x)

print("Repeated items:",tuple(rep))
