Data structures
dict_from_string(dict_str:str)->dict
This function will be given a single parameter, a string representing a dictionary. Your job is to convert the string into an actual dictionary and return the dictionary. Make sure all key-value pairs in the string exist in the newly created dictionary. The string will contain only numbers or single letters as key values pairs. Make sure all letters are kept as strings and all numbers are converted to integers in the newly created dictionary.
Example:
String Input: '{9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1}'
Expected: {9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1}
String Input: '{10: 'D', 1: 'Z', 5: 'a'}'
Expected: {10: 'D', 1: 'Z', 5: 'a'}
String Input: '{'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'}'
Expected: {'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'}

Exercise: empty_dictionary
Description
In this exercise, your function will receive no parameters.
It will create an empty dictionary and return it.
Function Name
empty_dictionary
Parameters
None
Return Value
An empty dictionary.
Examples
empty_dictionary() > 0)
Dictionaries:
Given the following dictionary definitions:
Foo = {1:’B’, 2:’D’, 3:’C’, 4:’A’}
Bar = {A:’3’,’B’:1,’C’:2,’D’:4}
Give the resulting value for each of the following expressions:
Foo[Bar[‘A’]]
Foo[Bar[‘B’]]
Bar[Foo[1]]
Bar[Foo[2]]
Use a for loop to display the key/value pairs in the above dictionary, one pair to a line.

- Given an alphanumeric list, separate it into three different lists stored in a dictionary: • The first list should only contain lowercase letters. • The second list should only contain uppercase letters. • The third list should only contain numbers. Each list stored in the dictionary should be stored in ascending order. Use the following naming convention when creating your lists: • numbers. • uppercase • lowercase Make sure that you adhere to the above instruction, as the name of your lists will be used to mark your function. Arguments: • character_list: (list) → list of alphanumeric characters. Return: dictionary (dict) → dictionary containing all three lists.
