#Quiz: Calculate
#In this quiz you're going to do some calculations for a tiler. Two parts of a floor need tiling. One part is 9 tiles wide by 7 tiles long, the other is 5 tiles wide by 7 tiles long. Tiles come in packages of 6.

#1. How many tiles are needed?
#2. You buy 17 packages of tiles containing 6 tiles each. How many tiles will be left over?




# Fill this in with an expression that calculates how many tiles are needed.
print()

# Fill this in with an expression that calculates how many tiles will be left over.
print()

#Note that this code uses scientific notation to define large numbers. 4.445e8 is equal to 4.445 * 10 ** 8 which is equal to 444500000.0.

# The current volume of a water reservoir (in cubic metres)
reservoir_volume = 4.445e8
# The amount of rainfall from a storm (in cubic metres)
rainfall = 5e6

# decrease the rainfall variable by 10% to account for runoff




# add the rainfall variable to the reservoir_volume variable




# increase reservoir_volume by 5% to account for stormwater that flows into the reservoir in the days following the storm




# decrease reservoir_volume by 5% to account for evaporation




# subtract 2.5e5 cubic metres from reservoir_volume to account for water that's piped to arid regions.





# print the new value of the reservoir_volume variable

#Quiz: Assign and Modify Variables
#Now it's your turn to work with variables. The comments in this quiz (the lines that begin with #) have instructions for creating and modifying variables. After each comment write a line of code that implements the instruction.

#Note that this code uses scientific notation to define large numbers. 4.445e8 is equal to 4.445 * 10 ** 8 which is equal to 444500000.0.

# Write your function here. Make sure to use "population_density" as the name of the fucntion. so, the test below works.



# test cases for your function Dont change anything below this comment.

test1 = population_density(10, 1)
expected_result1 = 10
print("expected result: {}, actual result: {}".format(expected_result1, test1))

test2 = population_density(864816, 121.4)
expected_result2 = 7123.6902801
print("expected result: {}, actual result: {}".format(expected_result2, test2))

#Quiz: List Indexing
#Use list indexing to determine how many days are in a particular month based on the integer variable month, and store that value in the integer variable num_days. For example, if month is 8, num_days should be set to 31, since the eighth month, August, has 31 days.

#Remember to account for zero-based indexing!



month = 8
days_in_month = [31,28,31,30,31,30,31,31,30,31,30,31]

# use list indexing to determine the number of days in month


print(num_days)

#Quiz: Slicing Lists
#Select the three most recent dates from this list using list slicing notation. Hint: negative indexes work in slices!

#COUNT UNIQUE WORDS

#Your task for this quiz is to find the number of unique words in the text. In the code editor below, complete these three steps to get your answer.
#1. Split verse into a list of words. Hint: You can use a string method you learned in the previous lesson.
#2. Convert the list into a data structure that would keep only the unique elements from the list.
#3. Print the length of the container.

#Tag Counter
#Write a for loop that iterates over a list of strings, tokens, and counts how many of them are XML tags. XML is a data language similar to HTML. You can tell if a string is an XML tag if it begins with a left angle bracket "<" and ends with a right angle bracket ">". Keep track of the number of tags using the variable count.

#Count By Check
#Suppose you want to count from some number start_num by another number count_by until you hit a final number end_num, and calculate break_num the way you did in the last quiz.

#Now in addition, address what would happen if someone gives a start_num that is greater than end_num. If this is the case, set result to "Oops! Looks like your start value is greater than the end value. Please try again." Otherwise, set result to the value of break_num.

# write a while loop that uses break_num as the ongoing number to
# check against end_num

#Count By
#Suppose you want to count from some number start_num by another number count_by until you hit a final number end_num. Use break_num as the variable that you'll change each time through the loop. For simplicity, assume that end_num is always larger than start_num and count_by is always positive.

#Before the loop, what do you want to set break_num equal to? How do you want to change break_num each time through the loop? What condition will you use to see when it's time to stop looping?

#After the loop is done, print out break_num, showing the value that indicated it was time to stop looping. It is the case that break_num should be a number that is the first number larger than end_num.

#Practice: Which Prize
#Write an if statement that lets a competitor know which of these prizes they won based on the number of points they scored, which is stored in the integer variable points.

#Points Prize
#1 - 50 wooden rabbit
#51 - 150 no prize
#151 - 180 wafer-thin mint
#181 - 200 penguin
#All of the lower and upper bounds here are inclusive, and points can only take on positive integer values up to 200.

#In your if statement, assign the result variable to a string holding the appropriate message based on the value of points. If they've won a prize, the message should state "Congratulations! You won a [prize name]!" with the prize name. If there's no prize, the message should state "Oh dear, no prize this time."

#Note: Feel free to test run your code with other inputs, but when you submit your answer, only use the original input of points = 174. You can hide your other inputs by commenting them out.

Using your idea on how to copy files, and read/write to binary file.

Write a program that makes a copy of any named *.jpg* image file in the same folder.

The program first requests for the name (without file extension) of the *jpg* image file to be duplicated. It then opens the named image (as a binary file) (now with *.jpg* extension) in the working directory and makes a copy of it in the same directory.

� _If for example, the user's input is *Myimage*, the program makes a duplicate of *Myimage.jpg* (already existing in the folder), and saves the new file as *Myimage - Copy.jpg*. The same folder now contains two same images with different names._

Additionally, when an attempt is made to open a non-existing file in read mode, a *FileNotFoundError* exception is raised. Prevent your program from 'crashing' when the user enters the name of a non-existing image file in your folder. Your program prints *"File not found!"* on such occurence.

(You may need to create a new folder, and move one of your jpeg pictures into the folder. You then write and save your program in the same new folder. After executing the program, you should have two images (one, a duplicate).

Nice one

Question 9
Use Python to calculate how many different passwords can be formed with 6 lower case English letters. For a 1 letter password, there would be 26 possibilities. For a 2 letter password, each letter is independent of the other, so there would be 26 times 26 possibilities. Using this information, print the amount of possible passwords that can be formed with 6 letters.
