In this tutorial, we will program 'How to Update an Element in a List using Python'. We will learn how to update an element in a list in Python. The main goal here is to create a safe way to store temporary updated data in your current list. I will provide a sample program to demonstrate the actual coding of this tutorial.
This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for updating an element in a list. I will do my best to provide you with the easiest method of updating any element in a list. So, let's start with the coding.
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
while True: ret = False print("====================== Update Element in a List ====================== ") myList = ['JavaScript', 'Java', 'PHP']; print("\nMy current List: ", myList); print("\n") sel = int(input("Select an element index to change(1-3): ")) if sel > 3: print("Error Selection!") break else: el = input("Enter your element: ") myList[sel-1] = el print("My new List: ", myList) opt = input("Do you want to update again?(yes/no): ") if opt.lower() == 'yes': ret=False elif opt.lower() == 'no': ret=True print("Exiting program....") else: print("Please enter yes/no:") break if ret == False: continue
In the provided code, we simply enclosed the code with a while loop to allow for continuous execution of the program. To update the current list, the trick here is that you need to select the index position first of the said element. Then, set that with the new element you are about to enter from the input.
