Interact basics

Write a print_sum function that prints the sum of its arguments a and b.


In [9]:
def print_sum(a, b):
    print(a + b)

Use the interact function to interact with the print_sum function.

  • a should be a floating point slider over the interval [-10., 10.] with step sizes of 0.1
  • b should be an integer slider the interval [-8, 8] with step sizes of 2.

In [11]:
# YOUR CODE HERE
interact(print_sum, a=(-10.0, 10.0, 0.1), b=(-8, 8, 2));

Write a function named print_string that prints a string and additionally prints the length of that string if a boolean parameter is True.


In [17]:
def print_string(s, length=False):
    print(s)
    if length == True:
        print(len(s))

Use the interact function to interact with the print_string function.

  • s should be a textbox with the initial value "Hello World!".
  • length should be a checkbox with an initial value of True.

In [22]:
# YOUR CODE HERE
interact(print_string, Length=True, s="");




In [21]:
assert True # leave this for grading the print_string exercise
