test_function(l,w,h)- AThe area of the box is 125
- BThe area of the box is 125.0
- CThe area of the box is 120
- D125.0
6What will the output of this program be when it is executed?
def test_function( length, width, height):
print ("the area of the box is ", length*width*height)
return length*width*height
l = 12.5
w = 5
h = 2
test_function(l, w, h)
print ("The area of the box is ", length*width*height)- AA NameError because a variable is not defined
- BThe area of the box is 125.0
- CThe are of the box is 0
- DA SyntaxError due to illegal function call
7What will the output of the following code be?
def recursive( depth ):
depth+=1
while (depth < 5):
ret = recursive(depth)
return depth
ret = recursive( 0 )
print ("the recursive depth is ", ret)- AThe recursive depth is 5
- BThe recursive depth is 4
- CError due to depth of recursive calls
- DNone

print (i)- A0

9What output will the following Python script produce?
def function2(param):
print (param, param)
def function1(part1, part2):
cat = part1 + part2
function2(cat)
chant1 = "See You"
chant2 = "See Me"
function1(chant1, chant2)- ASee You See Me
- BSee You See Me See You See Me
- CSee Me See Me See You See You

- BIt changes the format of the string in the script
- CIt opens a file for StringIO functions to read
- DIt includes a Python module called StringIO into the script
11The following Python script will generate an error when executed. What is the cause of the error?
def function2(param):
print (param, param)
print (cat)
def function1(part1, part2):
cat = part1 + part2
function2(cat)
chant1 = "See You"
chant2 = "See Me"
function1(chant1, chant2)- AThe variable cat is local to function1 and cannot be used in function 2
- BThe variable param is used twice in function2 and this is illegal
- CFunction2 does not have a return value defined
- DFunction1 does not have a return value defined
