You can use ‘enumerate()‘ in Python to loop over an iterable (such as a list, tuple, or string) while also keeping track of the index of the current item. 1. Use ‘enumerate()‘ with a list: Copy my_list = [“apple”, “grape”, “mango”, “peach”, “lemon”]for idx, item in enumerate(my_list): print(idx, item) The result: To specify the start … Read more
To find the middle item in a Python List (for both odd and even number of items): Copy my_list = [1, 2, 3, 4, 5]if not my_list: raise ValueError(“List is Empty”)else: mid_item_index = len(my_list) // 2 if len(my_list) % 2 == 0: mid_item_value = my_list[mid_item_index – 1: mid_item_index + 1] else: mid_item_value = my_list[mid_item_index]print(mid_item_value) The … Read more
To count the number of times a character appears in a string in Python (both in upper and lower case): Copy my_string = “Sunny Universe”desired_character = “U”count = 0for char in my_string: if char.lower() == desired_character.lower(): count += 1print(count) Here, the letter “U” appears twice (in upper and lower case) : Another approach: Copy my_string … Read more
