## Welcome to HW2-3 task 1!
## There are 12 questions in this homework. Related questions are grouped together.
## Q2, Q3, Q6, Q8 all need you to answer in plain English. If you need more lines for your answer, 
## just start a new line and put a "#" at the beginning. 
## Q1, Q4, Q5, Q9, Q10, Q11, Q12 all need you to write programming statements.
## Q7 needs you to modify some programming statements, observe the result, and explain in English

# Your name and student ID here:


############################## Question 1 and 2 ############################

# Q2: What do you think that this function does?
# Your answer here:
def countToN(n):
	for i in range(1,n+1):
		print(i)

# We will ask the function to count to 10
countToN(10)

# Q1: Write a programming statement that asks countToN() to count to 100

############################## Question 3 and 4 ############################

# Q3: Just by looking at it, what do you think that this function does?
# Your answer here:
def printMyInfo(name, studentID):
	print("Hello, my name is", name, "and my student ID is", studentID) 


# Q4: Write a programming statement that will use the function printMyInfo() 
# to print out your name and studentID


############################## Question 5, 6 and 7 ############################

# Q6: What do you think that this function does?
# What do the variables a, b, and c do?
# Your answer here:
def addTwoNumbers(a, b):
    c = a+b
    return c;

# This programming statement calls addTwoNumbers()
x = addTwoNumbers(55, 101);
print("The sum of 55 and 101 is", x)

# Q5: Write a programming statement that calls addTwoNumbers() to add 103 and 927


# Q7: Instead of "return c", change the last line of addTwoNumbers() to return a.
# What is the result? Is this correct?



############################## Question 8 ############################

# Q8: In your own words, write down what a function does. Specifically, mention:
#  a. What do the things in parentheses (..) do?
#  b. What is the purpose of the return?
# You may find the equivalent from math useful: https://www.mathsisfun.com/sets/function.html
# Note: students from EE and EIE (and other engineering/construction depts) -- you MUST
#       answer this question IN YOUR OWN WORDS. Trust me, we can tell when you've just 
#       been copying from your lecture notes in the other class.


############################## Question 9 and 10 ############################

# Q9: Complete the following function, which sums up a list of numbers
def sumUpList(list1):
	sum = 0
	# go through the variable list1, update sum on each turn
	return sum

# Q10: Write programming statements to use sumUpList() to sum up the elements of a
#      list of numbers (you decide what the list should contain.


############################## Question 11 and 12 ############################

# Q11: Complete the following function, which checks if a given element is already
#      in a list. It returns True if the element already exists in the list; False if not.
def existsInList(myList, element):
	found = False
	# go through myList, update the variable found if needed.
	return found


# Q12: Given the following list and the word, call existsInList() to find out
#      whether the variables word1 and word2 exist in the list. Print out the answer
thisList = ["Tiger", "tiger", "burning", "bright"]
word1 =  "Tiger"
word2 = "TIGER"
