Write a program to print all keys and values of a dictionary using a loop.

 

student = {"name": "John", "age": 20, "grade": "A"}

for key, value in student.items():

    print(f"{key}: {value}")

Code Explanation: 

Define the Dictionary:

student = {"name": "John", "age": 20, "grade": "A"}

A dictionary named student is created with key-value pairs:

"name" → "John"

"age" → 20

"grade" → "A"

Loop Through the Dictionary:

for key, value in student.items():

The .items() method returns key-value pairs as tuples.

The for loop iterates through each key-value pair.

Print the Key-Value Pairs:

print(f"{key}: {value}")

The print() function formats and prints the key followed by its value.

Output:

name: John

age: 20

grade: A
