问题

I want to return two lists from a function in python. How can i do that. And how to read them in the main program. Examples and illustrations would be very helpful.

Thanks in advance.

You can return a tuple of lists, an use sequence unpacking to assign them to two different names when calling the function:

def f():
    return [1, 2, 3], ["a", "b", "c"]

list1, list2 = f()

回答2:

You can return as many value as you want by separating the values by commas:

def return_values():
    # your code
    return value1, value2

You can even wrap them in parenthesis as follows:

return (value1, value2)

In order to call the function you can use one of the following alternatives:

value1, value2 = return_values() #in the case where you return 2 values

values= return_values() # in the case values will contain a tuple
