Next, set the type of list to a string which will find the string element from the list. Finally, display the result by using the built-in function index() with a variable named Fruit_list. Example Open Compiler Fruit_list = ['Banana', 'Apple', 1000, 'Mango'] print("String present...
In this code block, we first define a listmy_listcontaining three strings: “apple”, “banana”, and “cherry”. Then, we use theinoperator to check if “banana” is present inmy_list. If it is, the code inside theifstatement is executed, printing “Found!” to the console. 2. U...

To find the index of minimum element in a list in python using the for loop, len() function, and the range() function, we will use the following steps.First, we will calculate the length of the input list using the len() function. We will store the value in a variable list_len. ...
