hat will the above Python code do?dict={"Phy":94,"Che":70,"Bio":82,"Eng":95} dict.update({"Che":72,"Bio":80})It will create new dictionary as dict={"Che":72,"Bio":80} and old dict will be deleted.It will throw an error as dictionary cannot be updated.It will simply update the dictionary as dict={"Phy":94,"Che":72,"Bio":80,"Eng":95}It will not throw any error but it will not do any changes in dict

Describe what will happen during the dictionary update dict[k] = v, if k isn’t present in dict.Select one:The program stops with a run-time errorThe entry (k, v) is added to the dictionaryThe program updates the key which is closest to kThe program continues with dict unchanged

Which of the following Python codes will give same output if(i) dict.pop("book")(ii) del dict["book"](iii) dict.update({"diary":1,"novel":5}) dict={"diary":1,"book":3,"novel":5}

Merge following two Python dictionaries into one                                                                                                            dict1 = {'Ten': 10, 'Twenty': 20, 'Thirty': 30}                                                                                                                                dict2 = {'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

Write a Python program to create a new dictionary by extracting the mentioned keys and create a new new dictionary and print it as the result.Constraints:Input Format:Output Format: Example:Input:{"name": "Kelly","age": 25,"salary": 8000,"city": "New york"}["name", "salary"]Output:{'name': 'Kelly', 'salary': 8000}Explanation:Dictionary = {"name": "Kelly","age": 25,"salary": 8000,"city": "New york"}Keys that needs to be extracted = ["name", "salary"]Result = {'name': 'Kelly', 'salary': 8000}Public Test Cases:# INPUT EXPECTED OUTPUT1 {"name": "Kelly","age": 25,"salary": 8000,"city": "New york"} ["name", "salary"] {'name': 'Kelly', 'salary': 8000}

What happens if you try to add a new key-value pair to a dictionary using a key that already exists in the dictionary? The new value overwrites the existing value An error is raised The dictionary becomes immutable The new value is appended to the existing value
