Python Coding Challange - Question With Answer(01230325)

 

Explanation of the Code:

1. Creating an Empty Dictionary:

   
   personsAges = dict()

   • This initializes an empty dictionary named personsAges.

2. Adding Key-Value Pairs:

   
   personsAges["Smith"] = 21
   personsAges["Mike"] = 27

   • Here, two key-value pairs are added to the dictionary:

     • "Smith" as the key with 21 as the value.

     • "Mike" as the key with 27 as the value.

3. Looping Through the Dictionary:

   
   for key, value in personsAges.items():
       print(key)

   • The .items() method retrieves key-value pairs from the dictionary.

   • The for loop iterates over these pairs.

   • key represents the names ("Smith", "Mike"), and value represents the ages (21, 27).

   • print(key) prints only the keys.

Expected Output:

Smith
Mike

Since only the key is printed, we get the names "Smith" and "Mike" as output.
