Here is a Python code to check the length of every element if it is equal to each other at the same time

def same_len(list):
    """
    Returns True if all elements in the list have the same length.
    """
    if len(list) < 2:
        return True
    for i in range(len(list)):
        if len(list[i])!= len(list[0]):
            return False
    return True

# Enter the list
list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# Calling the function
print((same_len(list)))

#Example Output
# True
