USING PYTHON! a) Programmatically (do not just write a definition!) create a dictionary whose keys are the integers 1 through 10 and whose respective values are the keys cubed (e.g. a key of 5 has a value of 125). b) Write a function that, given a user inputted string, outputs a dictionary where each letter is a key and each value is the letter’s position in the string. Note that you must handle cases where a word could contain the...

Write a function that takes a dictionary and a list of keys as 2 parameters. It removes the entries associated with the keys from the given dictionary Your function should not print or return anything. The given dictionary should be modified after the function is called Note: it means that you can't create another dictionary in your function. Since dictionaries are mutable, you can modify them directly def remove_keys (dict, key_list) "" "Remove the key, value pair from...

Storing data and adding to data in a dictionary: Experiment with Python dictionaries and their keys() member function that returns a list of a dictionary's keys. You can check if a particular key is in a dictionary by using the in test with the keys list. For example, if our dictionary is MyDict = { 1: 'One', 2: 'Two', 3: 'Three' } Then ( 2 in MyDict.keys() ) evaluates to True, indicating that 2 is a valid key for MyDict....
