Question

Does the pop() function on a dictionary just access the data or remove it?

Answer

The pop() function will return the value for the key AND then remove the key/value from the dictionary. The following code example shows the results of performing a pop() on a dictionary to remove the item indexed by key ā€œCā€.

letters = { "A": 10, "B": 20, "C": 30, "D": 40 }

value = letters.pop("C")

print(letters)
# {'A': 10, 'B': 20, 'D': 40}

is the .pop() in the dictionary a function or a method? how come in the lesson it specified as same with .get() method and here on the question and answer platform called function?
and can someone clarify difference between a function and a method?

Both .pop() and .get() are methods. Methods belong to a certain class, so can only be called on instance of that class. you can also recognize methods by the difference in calling style:

# calling print function
print("hello world")
# calling method
{}.get('a')
