Python | Count the elements in a list until an element is a Tuple
In this problem, we need to accept a list. The list can have nested tuples. We need to count the elements in a list until a tuple has been encountered.
Examples:
Input : [4, 5, 6, 10, (1, 2, 3), 11, 2, 4] Output : 4 Input : [4, (5, 6), 10, (1, 2, 3), 11, 2, 4] Output : 1
In this program we will use the concept of isinstance() to verify whether we are encountering a tuple or not in our path of count. For detailed guide on isinstance() visit isinstance in Python.
# Python program to count the items # until a list is encountered def Count(li): counter = 0 for num in li: if isinstance(num, tuple): break counter = counter + 1 return counter # Driver Code li = [4, 5, 6, 10, (1, 2, 3), 11, 2, 4] print(Count(li)) |
