The programmer wants the loop to display a sum of the first 10 integers. What kind of error occurs in the code and how can it be fixed?
numSum = 0
count = 1
while count <= 10:
numSum += count
count -= 1
print(numSum)
Logic error because the counter is decrementing instead of incrementing and causing an infinite loop.
count -= 1 Change to -> count += 1
In the code snippet below, what are the argument(s) of the function call?
def makeSerialNum(partNum):

What is the output of the following code if the user enters 5:
def findSquare(num = 6):
return num * num
num = input("Enter a number: ")
mySquare = findSquare()
print(num, "squared is", mySquare)
5 squared is 36
This is tricky but function was defined with num = 6. The input statement never went into findSquare() function.
hotPlate = 65 < 60
if hotPlate:
print("Be careful, hot plate!")
else:

What is the output from running the above code?
The plate is ready.
While loops can execute this possible number of times.
