Explanation

Below will create a Python dictionary named 'student' with three key-value pairs: name, age, and course.

Code:

student = {
'name': 'Praveen',
 'age': 25,
 'course': 'MERN'
}

Explanation

This accesses the value of the key 'name' from the dictionary and prints it. It will raise a KeyError if the key does not exist.

Code:

print(student['name'])

Explanation

The get() method returns the value of the specified key. If the key is not found, it returns None instead of raising an error.

Code:

print(student.get('age'))

Explanation

This adds a new key 'city' to the dictionary or updates it if it already exists.

Code:

student['city'] = 'Chennai'

Explanation

This loop iterates through all key-value pairs in the dictionary using the items() method.

Code:

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