How to Remove a Key from a Dictionary in Python
In this tutorial, we’ll learn how to program “How to Remove a Key from a Dictionary in Python.” The objective is to safely remove a specific key from a dictionary. This tutorial will guide you through the proper method for identifying and removing a key-value pair.
This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will illustrate the correct way to remove a key from a dictionary. So, let’s dive into the coding process!
Getting Started:
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/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- my_list = {"name": "John", "age": 21, "city": "New York"}
- while True:
- print("\n================= Remove a Key from a Dictionary =================\n\n")
- print("Mylist: ", my_list)
- remove_key = my_list.pop("age")
- print("\nList after removal: ", my_list)
- opt = input("\nDo you want to try 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
This Python program repeatedly removes the key "age" from a predefined dictionary, displays the updated result, and asks the user whether they want to try again, handling input validation to ensure only "yes" or "no" responses are accepted.
Output:
