Question

1. Questions

Python Code: For each line of code, write the type of error (syntax, semantics, runt-time), cause of the error, and your fix.

(1) def fun(num letter)

(2) num == 7 + num

(3) return 'num' - letter

(4) result = fun(5, x)

2. Question

Python Code: Run the code below to check the outputs of the print() call on lines 12. And :

A) Analyze the application of the accumulation pattern and answer the following questions:

#1. a. What is the accumulator variable? ________________

#1. b. What's its data type? _____________

#1. c What's the purpose of it?

#2. a What's the loop variable? _____________

#2. b What's its data type? ________________

#2. c What's the purpose of it?

#3 How many iterations does the for loop have? _________

#4 Write the line(s) of code where the accumulator "accumulates" something into it ________________

#5 What gets accumulated into the accumulator? Explain in English.

B) Modify the value of labs variable such that it has the 9th element, 'lab6old'. Run the program again.

       #1. What do you get? Copy and paste the output from Scratchpad in here.

      #2. Explain the result.

labs = ['lab1a', 'lab1b', 'lab2', 'lab3', 'lab4a', 'lab4b', 'lab4c', 'lab5']

graded = ''

tutor_code = ''

for lab in labs:

    lab_num = int(lab[3])

    tutor_code = lab[3]

    if len(lab) == 5:

        tutor_code = tutor_code + lab[4]

        graded = graded + lab + ' assigned to ' + tutor_code + '\n'

    elif len(lab) < 5:

        graded = graded + lab + ' not assigned\n'

print(graded)

#please ask 1 question at a time. I have done the 1st one

def fun(num,letter):#syntax error, function definition is ended by :, arguments are to be separated by a comma
num = 7 + num#symantic error, we need to assign and not compare, which does nothing here
return str(num) + letter #run time error, we cant subtract a number from character,
#we can append it however to string representation

result = fun(5, 'x')#run time error, x should be a pre defined variable, or should be passed as string

def fun(num, letter): #syntax error, function definition is ended by :, arguments are to be separated by a comma num = 7 + num#symantic error, we need to assign and not compare, which does nothing here return str(num) + letter #run time error, we cant subtract a number from character, #we can append it however to string representation result = fun(5, 'x')#run time error, x should be a pre defined variable, or should be passed as string print(result) 12x
