Write a print_sum
function that prints
the sum of its arguments a
and b
.
In [47]:
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 0.1
b
should be an integer slider the interval [-8, 8] with step sizes of 2
.
In [48]:
interact(print_sum, a = (-10.0,10.0,1.0), b = (-8.0,8.0,2.0));

assert True # leave this for grading the print_sum exercise
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 [45]:
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 [46]:
interact(print_string, s = 'Hello World!', length=True);
In [44]:
assert True # leave this for grading the print_string exercise
