Which of the following lines properly starts a function using two parameters, both with zeroed default values?

• fun fun(a, b=0):
• def fun(a=b=0):
• fun fun(a=0, b):
• def fun(a=0, b=0):

Explanation: The correct way to define parameters with default values is to state the name of the variable, the assignment sign (=), and the default value, e.g. a=0. If there are more default values, separate them with commas.
