4) Delete set of keys from Python Dictionary Given: sampleDict = { “name”: “Kelly”, “age”:25, “salary” : 8000, “city”: “New york” } keysToRemove = [“name”, “salary”] Expected output: {‘city’: ‘New york’, ‘age’: 25}

1) Write a Python program to iterate over dictionaries using for loops d = {‘X’: 10, y: 20, ‘z’: 30) 2) Write a Python program to get the maximum and minimum value in a dictionary my_dict = {‘X’:500, ‘y’:5874, ‘z’: 568} Sample Output: X-> 10 Y -> 20 2 -> 30 3) Given a Python dictionary, Change Brad’s salary to 8500 sampleDict = { ’empl’: {‘name’: ‘Jhon’, ‘salary’: 7500), ’emp2′: {‘name’: ‘Emma’, ‘salary’: 8800), emp3′: {‘name’: ‘Brad’, ‘salary’: 6500) } Expected output: sampleDict empi’: {‘name’: ‘Jhon’, ‘salary’: 7500), ’emp2′: {‘name’: ‘Emma’, ‘salary’: 8800), ’emp3′: {‘name’: ‘Brad’, ‘salary’: 8500) )
