Interact basics

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



In [10]:

    
def print_sum(a, b):
    """Print the sum of the arguments a and b."""
    print(a + b)
    #raise NotImplementedError()

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]:

    
interact(print_sum, a = (-10., 10., 0.1), b = (-8, 8, 2));
#raise NotImplementedError()

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 [15]:

    
def print_string(s, length=False):
    """Print the string s and optionally its length."""
    print(s)
    if length:
        print(len(s))
    #raise NotImplementedError()

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 [16]:

    
interact(print_string, s = "Hello World!", length = True);
#raise NotImplementedError()









    



Hello World!
