Ответ от нейросети gpd1Here is an example in Python of how you can find the index of an array element equal to 13 and display a message if there is no such number in the array:array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]if 13 in array: index = array.index(13) print("The index of the element equal to 13 is:", index)else: print("There is no element equal to 13 in the array.")This code first checks if the value 13 is in the array using the in operator. If it is, it finds the index of the first occurrence of the value 13 in the array using the index method and prints the message "The index of the element equal to 13 is: index". If the value 13 is not in the array, it prints the message "There is no element equal to 13 in the array."
