Python How To Unpack List Tuple Or Dictionary To Function Arguments
Unpacking Tuples as Arguments to Function Calls Python even provides a way to pass a single tuple to a function and have it be unpacked for assignment to the named parameters This won t quite work It will cause an error because the function add is expecting two parameters but you re only passing one parameter a tuple 13 5 Unpacking Tuples as Arguments to Function Calls. 01 08 Python provides a mechanism to solve this and we re going to take a look at that now It s called argument tuple packing The syntax is when you precede a parameter name in a function definition with an asterisk 01 22 It s an indication that you re going to use this feature of argument tuple packing Named tuples can be used to provide a way to pass named arguments to functions instead of using simple tuples or dictionaries This feature was added in Python 3 6 and is a great addition to the language s functionality Advantages of using Named Tuples as Function Arguments
