3. Write a python program to sort the order of programming based on its alphabet sequence with list of dictionaries, programmer is provided. The expected answer is in the following output for better understanding.

The output is:

programmer =
[{'Name':'Mark', 'Programming':'Python', 'Year of Experience': 3},
{'Name':'Nicole', 'Programming':'C', 'Year of Experience': 1},
{'Name':'Jason', 'Programming':'R', 'Year of Experience': 10}]

Expected Answer:
The initil list of dictionaries :
[{'Name': 'Mark', 'Programming': 'Python', 'Year of Experience': 3},
{'Name': 'Nicole', 'Programming': 'C', 'Year of Experience': 1},
