Answer 1

Answer:

- To get the items of a dictionary and print them as a string, use the items() method to unpack the keys and values in a for and print or write them into a file.

for key, value in mydict.items():

   print(f"{key}, {value}")

- To convert string from user input into dictionary;

   mystring = input().split(" ")  #assuming the words are separated by a space.

   from word in mystring:

       mydict[word] = mydict.get(word, 0) + 1

This would use the words in the string as the keys of the dictionary and the count of each word as the respective values.

Explanation:

A dictionary is a data structure in python used to store data in key-value pairs. The items are enclosed in curly braces and can be accessed with the key in dot or bracket notation.
