Python

Write a program that reads a sequence of numbers ended by 0 and print all the numbers that repeat at least twice.

Sample Input

3 4 3 7 2 2 1 3 0 

Sample Output

3 2 

lst = [] cns = [] while True: ----n = int(input()) ----if n != 0: -------lst.append(n) ----elif n == 0: -------lst.append(n) -------break for i in lst: ----x = lst.count(i) ----if x >= 2: -------if x not in cns: ----------cns.append(x) for i in cns: ----print(i,end=' ')

this is what i did, but it give me a EOFError : EOF when reading the line 14 : " n = int(input())"
