"""Write a regular expression that can detect dates in the DD/MM/YYYY for-
mat. Assume that the days range from 01 to 31, the months range from 01 
to 12, and the years range from 1000 to 2999. Note that if the day or month 
is a single digit, it’ll have a leading zero.
The regular expression doesn’t have to detect correct days for each 
month or for leap years; it will accept nonexistent dates like 31/02/2020 or 
31/04/2021. Then store these strings into variables named month, day, and 
year, and write additional code that can detect if it is a valid date. April, 
June, September, and November have 30 days, February has 28 days, and 
the rest of the months have 31 days. February has 29 days in leap years.

Write a program that asks users for their sandwich preferences. The pro-
gram should use PyInputPlus to ensure that they enter valid input, such as:
•	 Using inputMenu() for a bread type: wheat, white, or sourdough.
•	 Using inputMenu() for a protein type: chicken, turkey, ham, or tofu.
•	 Using inputYesNo() to ask if they want cheese.
•	 If so, using inputMenu() to ask for a cheese type: cheddar, Swiss, 
or mozzarella.
•	 Using inputYesNo() to ask if they want mayo, mustard, lettuce, or tomato.
•	 Using inputInt() to ask how many sandwiches they want. Make sure this

To see how much PyInputPlus is doing for you, try re-creating the multipli-
cation quiz project on your own without importing it. This program will 
prompt the user with 10 multiplication questions, ranging from 0 × 0 to 
9 × 9. You’ll need to implement the following features:
•	 If the user enters the correct answer, the program displays “Correct!” 
for 1 second and moves on to the next question.
•	 The user gets three tries to enter the correct answer before the 
program moves on to the next question.
•	 Eight seconds after first displaying the question, the question is

Extending the Multi-Clipboard
Extend the multi-clipboard program in this chapter so that it has a delete 
<keyword> command line argument that will delete a keyword from the shelf. 
Then add a delete command line argument that will delete all keywords.
'''
#! python3
# mcb.pyw - Saves and loads pieces of text to the clipboard.
# Usage: py.exe mcb.pyw save <keyword> - Saves clipboard to keyword.
#        py.exe mcb.pyw <keyword> - Loads keyword to clipboard.

Create a Mad Libs program that reads in text files and lets the user add 
their own text anywhere the word ADJECTIVE, NOUN, ADVERB, or VERB 
appears in the text file. For example, a text file may look like this:
The ADJECTIVE panda walked to the NOUN and then VERB. A nearby NOUN was 
unaffected by these events.
The program would find these occurrences and prompt the user to 
replace them.
Enter an adjective:
silly

Write a program that opens all .txt files in a folder and searches for any 
line that matches a user-supplied regular expression. The results should 
be printed to the screen.

Selective Copy
Write a program that walks through a folder tree and searches for files with 
a certain file extension (such as .pdf or .jpg). Copy these files from whatever 
location they are in to a new folder.

Deleting Unneeded Files
It’s not uncommon for a few unneeded but humongous files or folders to 
take up the bulk of the space on your hard drive. If you’re trying to free up 
room on your computer, you’ll get the most bang for your buck by deleting 
the most massive of the unwanted files. But first you have to find them. 
Write a program that walks through a folder tree and searches for excep-
tionally large files or folders—say, ones that have a file size of more than 
100MB. (Remember that to get a file’s size, you can use os.path.getsize() from 
the os module.) Print these files with their absolute path to the screen.

Filling in the Gaps
Write a program that finds all files with a given prefix, such as  spam001.txt, 
spam002.txt, and so on, in a single folder and locates any gaps in the num-
bering (such as if there is a spam001.txt and spam003.txt but no spam002.txt). 
Have the program rename all the later files to close this gap.
As an added challenge, write another program that can insert gaps 
into numbered files so that a new file can be added.

2048
2048 is a simple game where you combine tiles by sliding them up, down, 
left, or right with the arrow keys. You can actually get a fairly high score 
by repeatedly sliding in an up, right, down, and left pattern over and over 
again. Write a program that will open the game at https://gabrielecirulli 
.github.io/2048/ and keep sending up, right, down, and left keystrokes to 
automatically play the game.
