Python:

Exercise 1: Nested Dictionaries

• Create a new function called AddNewFullContact
  • Add a parameter that will be a dictionary that we will store a collection of contacts with their associated contact info
  • Ask the user for the following information:
    • name - "Please enter the name of your friend: "
    • number - "What is your friend's 7-digit phone number? ", "That's not 7 digits, try again: "
    • email - "What is your friend's email address? "
    • age (between 0 and 125, inclusive) - "What is your friend's age? ", "That's not a real age, try again: "
  • Store the "number", "email", and "age" (be sure to use exactly those words) into a new dictionary (not the function's parameter!) that will represent name's contact info
  • Store the entire dictionary into the contacts dictionary using name as its key
• Using a loop, add 5 contacts to the dictionary using AddNewFullContact
• Pretty print the dictionary
• Print all of the names in the dictionary (hint: keys)
• Print all of the full contact info in the dictionary (hint: values)
• Ask the user for the name they want to look up, "Whose number do you want? "
• Pretty print this contact's full contact info
• Print out just the email associated with that name
