Write a print_sum function that prints the sum of its arguments a and b.
In [3]:
def print_sum(a, b):
c = a + b
print c
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 0.1b should be an integer slider the interval [-8, 8] with step sizes of 2.
In [4]:
interact(print_sum, a = (-10., 10., 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 [9]:
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 [10]:
interact(print_string, s = 'Hello World!', length = True)
In [ ]:
assert True # leave this for grading the print_string exercise
