Argument Syntax

Let's Learn Extended Argument Syntax!

Call the function using the textbox given there and see the output and observations given below.

The function on the right calculates the simple interest on a given principal, interest rate and time. If the time is not given, it is assumed to be 10 years. If the interest rate is not given, it is assumed to be 7%.

Fill in the blank with a comma separated list of 1, 2 or 3 numbers to find out the use of default arguments.

Press Reset to clear the text box and reset the animation.

Run the program

def simple_interest(principal, interest_rate=7, years=10): interest = principal * interest_rate * years / 100 amount = principal + interest return amount print(simple_interest())

Submit

Output is:

Observations

Principal

Rate=7

Time=10

Let's Learn Extended Argument Syntax!

Call the function using the textbox given there and see the output and observations given below.

The function on the right calculates the sum of all the arguments passed to it. It does this using the *args approach to take in an arbitrary number of arguments.

Fill in the blank with a comma separated list of numbers to find out the use of variable arguments.

Run the program

def sum(*numbers): total = 0 for number in numbers: total += number return total print(sum())

Submit

Output is:

Observations

sum
