# What does Python evaluate each of the
# following lines to be
# (and what are the types of each expression):
9 % 4
12 % 4
9 // 4
9 / 4
"34" + "10"


# Suppose S is the string "BCC Math".
# How does Python evaluate the following
# expressions
S = "BCC Math"
S[2]
S[2:6]
S[2:]
S[:2]
S[:-2]
S[3:-2]
4 < 3
2 == "2"
S[2] == "C"

# What does the following code print?
# Make a flowchart of the program.
k = -5
if k > 0:
    print(k)
elif k < -5:
    print(k*2)
elif k == -4.9:
    print(k+2)
else:
    print(k - 1)
print(k+10)



# What is the value of k after running the
# following program?
# Show your work by doing a trace.
k = 2
k = -5
if k > 0:
    k = k + 2
elif k < -5:
    k = k*2
elif k == 2:
    k = k - 1
else:
    k = k**2







# What does the following code print
L = [9, 8, 4, 100]
if L[2] > 7:
    L[2] = 7
else:
    L[2] = 0

print(L)

# 1
# Write a program that swaps the values in
# variables A and B.


# 2
# Write a program that takes in 5 numbers
# as user input and prints their average.


# 3
# Write a program that prompts the user
# for two numerical inputs (L and W)
# and prints out the area and perimter of a rectangle
# with length L and width W.


# 4
# Do the last program again, but do it so
# that it complains if either the length
# or width is not a valid number and quits.



# 5
# One pound is 0.45kg.
# 1) Write a program that takes gets a number
#    as user input and prints out its conversion
#    to kg.
# 2) Write a program that takes a number
#    as user input and outputs its conversion
#    to pounds



# 6
# Write a program that takes 3 numbers as
# user input and prints out the minimum of the 3
# numbers


# 7
# Write a program that takes 3 positive
# numbers as user input and prints out the middle
# number if the 3 numbers are distinct,
# and outputs -1 if they are not distinct


# 8
# Write a program that takes a positive
# integer n as user input, and prints out the number
# of positive even integers less than n.
