def firstTimeOccuringIndex(dataArray,N):
    count = 0
    for i in range(0,len(dataArray)):
        if(dataArray[i] == N):
            print("{} is First Time Occuring at Index {}.".format(N,i))
            break

data = [77,43, 65, 12, 23, 12, 36, 85, 12, 25, 12, 42]
print("Data: ",data)
n = int(input('Enter Occur Element Value: '))
firstTimeOccuringIndex(data,n)

Output:

Data:  [77, 43, 65, 12, 23, 12, 36, 85, 12, 25, 12, 42]
