Human: finding an element in an tuple list. Assistant: 
Here is a Python function for finding an element in a list of tuple lists

import numpy as np

def find_element(list_of_tuples, element):
    """Finds an element in a list of tuples."""
    for i in range(len(list_of_tuples)):
        if list_of_tuples[i] == element:
            return i
    return -1

# Enter the list of tuples
list_of_tuples = [(1,2),(3,4),(5,6)]

# Enter the element
element = (2,3)

# Calling the function
print((find_element(list_of_tuples, element)))

#Example Output
# -1
