# Remove element using pop()
student = {"name": "John", "age": 20, "grade": "A", "city": "Delhi"}

# pop() removes key and returns value
removed_age = student.pop("age")
print(f"Removed 'age': {removed_age}")
print("After pop('age'):", student)

# pop() with default value (no error if key missing)
removed_grade = student.pop("grade", "Key not found")
print(f"Removed 'grade': {removed_grade}")
print("After pop('grade'):", student)

# Trying to pop non-existent key without default
try:
    student.pop("country")
except KeyError as e:
    print(f"\nError: {e} - key not found")

# pop with default for missing key
