Consider the following scenario about using Python dictionaries:

A teacher is using a dictionary to store student grades. The grades are stored as a point value out of 100. Currently, the teacher has a dictionary setup for Term 1 grades and wants to duplicate it for Term 2. The student name keys in the dictionary should stay the same, but the grade values should be reset to 0.

Complete the setup_gradebook function so that input like {"James": 93, "Felicity": 98, "Barakaa": 80} will produce a resulting dictionary that contains {"James": 0, "Felicity": 0, "Barakaa": 0}. This function should:

1.accept a dictionary old_gradebook variable through the functions parameters;

2.make a copy of the old_gradebook dictionary;

3.iterate over each key and value pair in the new dictionary;

4.replace the value for each key with the number 0;

5.return the new dictionary.

def setup_gradebook(old_gradebook):

# Use a dictionary method to create a new copy of the "old_gradebook".

___

# Complete the for loop to iterate over the new gradebook.

for ___

# Use a dictionary operation to reset the grade values to 0.

___

return new_gradebook

fall_gradebook = {"James": 93, "Felicity": 98, "Barakaa": 80}

print(setup_gradebook(fall_gradebook))

# Should output {'James': 0, 'Felicity': 0, 'Barakaa': 0}
