Python Function Type Arguments

""" Function Type Arguments""" """1.

Default Arguments - Assigning a default value to the function parameter makes it a default argument for the function - if a postional/keyword arg value is passed to a default arg, the default gets overwritted with the value - Note : if the fn. has a default argument , it should be defined after all the positional arguments""" def default_arg (user, job, salary = 10000): print(user, job, salary) default_arg('Ken','Tech Engineer') default_arg('Kenny','Field Engineer',5000) default_arg('Ken_Z',45000) default_arg('Ken_B','Tech Engineer',salary =9000) print() """4.
