This assignment is based on Exercise 8.4 from your textbook. Each of the following Python functions is supposed to check whether its argument has any lowercase letters.
For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect.
# 1
def any_lowercase1(s):
for c in s:
if c.islower():
return True
else:
return False
# 2
def any_lowercase2(s):
for c in s:
if 'c'.islower():
return 'True'
else:
return 'False'
# 3
def any_lowercase3(s):
for c in s:
flag = c.islower()
return flag
# 4
def any_lowercase4(s):
flag = False
for c in s:
flag = flag or c.islower()
return flag
# 5
def any_lowercase5(s):
for c in s:
if not c.islower():
return False
return True
Explanation:
#1 is wrong because if the first character is not lowercase, it stops and returns false, ignoring all the other characters. It can be fixed by removing the else: statement and moving the return False statement outside of the loop.
This is efficient; if one lowercase character is encountered, the function 'knows enough' and can return true. Only if no lowercase is encountered it has to loop all the way to the end.
You can try this out on repl.it.
Many of the others functions have problems in them. #4 looks OK.

Which of the following image file formats use lossless file compression? Choose all that apply.
BMP
GIF
JPEG
PNG
RAW
TIFF
Answer:
GIF
PNG
TIFF
Explanation:
I did this already. :)
BMP, PNG, RAW, and TIFF formats use lossless file compression. Therefore, options A, D, E, and F are correct.
What is lossless file compression?Lossless file compression is a data compression technique that reduces the size of a file without losing any of its original data. In other words, when a file is compressed using a lossless compression algorithm, it can be decompressed to its exact original form without any loss of information.
This is in contrast to lossy compression, which involves removing some data from the file in order to achieve a smaller size. Lossless compression works by identifying patterns and redundancies within the data and replacing them with more efficient representations.
Thus, BMP, PNG, RAW, and TIFF formats use lossless file compression. Therefore, options A, D, E, and F are correct.

Then before I could think, I saw nothing,but darkness, even though my eyes were open. After that, I saw a room that looked fairly familiar. For a quick second ,I had deja vu, then I was aware that it was my classroom. I saw myself smiling out of excitement, and holding a piece of paper. I was very confused, and I thought maybe it was just all in my head, or maybe it was just some weird deja vu that I have never experienced. I returned back to class very puzzled.
As we all began the test, I completely forgot about what happened. I was too focused on the test. 40 minutes passed, and everyone had already completed their assignment. My palms began sweating out of nervousness. Everyone in the room was waiting for me to finish. I had an immense feeling that everyone was staring at me,but I did not bother to look away from my test paper. Subsequently after 20 minutes,I concluded the test. I walked up to the teacher, and handed over my test answers to her. I never really felt this nervous over a test before. I was always usually confident in my answers. I had a sick feeling in my stomach. It was all making me start to believe that I wasn’t going to succeed on this test. After school,the teacher planned to give us our test results. I was afraid, and not ready. As she handed me over my results,she had a big smile on her face. Before I could say, or think anything other than me failing,she congratulated me, and patted me on the back,”Jax, you obtained all the answers right!’ My eyes got big in total shock. I gently grabbed my test results from her hand, and smiled. I was so joyful. I quickly ran out of the classroom door and waved goodbye to my teacher. “What a relief!’,I thought.
After that,I ran home, still as happy, and excited. When I got home, I tripped on the doormat that my mother owns outside of the house. I unfortunately fell on my face. It hurt so badly. At the moment I tried getting up,the weird feeling came back again. It was as if everything blacked out. All I saw was pure black for a couple seconds, as I did last time. I distinguished, and made out a strange picture of my mother having a paper towel on her hand, and lathering it on my face. Once I fully realized what the ‘picture’ I saw was, my heart started throbbing, repeatedly. The picture gradually faded away out of my eye sight. After it all went away,everything was back to normal. As I was done rubbing my eyes from confusion, I noticed that my Mother was standing right in front of me. She grabbed me by my hand and helped me get back up. She asked,”What just happened,Jax?” “I don-, I don’t know,Mom.”,I stuttered. She told me to follow her. She then led me to the kitchen table, and told me to sit down. I slowly sat down, holding on to the kitchen table. She swiftly ran towards the paper towels, and tried ripping a couple out as fast as she could, and ran back to me. She gently lathered, and patted the paper towel onto my forehead. I was confused and had no clue on why she was doing that. I asked her,”What’s on my forehead,Mom?” “You’re bleeding,I think you somehow fell, and landed on your face.” Right after she spoke,I remembered everything again. I wasn’t planning on telling her about what I saw after I tripped, sense I knew she would not believe me. “Oh yes! I tripped on your doormat outside the door.”,I responded. She apologized, and I quickly forgave her with no hesitation. She let me head off to my room afterwards.

write a loop that finds the sum of the numbers between 7 and 34
THIS IS FOR PYTHON
total = 0
for i in range(7, 35):
total += i
print(i)
print(total)
I forgot the reason but python always stops one number before your desired value. So that's why it's 35
The loop that finds the sum of the numbers between 7 and 34 i2 as follows:
x = 0
for i in range(7, 35):
x += i
print(x)
The code is written in python.
The variable x is initialise with the value zero.
For loop is used to loop through the range of value 7 to 35, excluding 35.
The looped values are then added to the variable x
The final sum is then printed out using the print statements in python.

write python program to find sum(using while/loop): sum= 1+ 2+ 4+8+ 16+ 32+....1024
Answer:
i = 0
total = 0
while i <= 10:
total += pow(2, i)
i += 1
print(total)
Explanation:
When you look the equation, you would realize that it is the sum of the numbers that are 2 to the power of i where 0 <= i <= 10
Set i and total as 0
Create a while loop that iterates while i is smaller than or equal to 10. Add the 2 to the power of i to the total (cumulative sum). Note that we use pow() method to calculate the power. At the end of the loop, increment the i by 1. Otherwise the loop will be an infinite loop.
When the loop is done, print the total

copy the 900 MB file. Bruce needs to have a ______
drive to rerecord data on the used DVD.
1. options
CD
hard disk
DVD
2. options
DVD-RR
DVD-recordable
DVD-RW
Answer:
The answer to this question is DVD and DVD-RW
Explanation:
The types of storage disk drives that can use in the given situation are;
Amy can hand over a DVD to Bruce to copy a 900 MB file. Bruce needs to have a "DVD-RW drive" to record data on the used DVD.
What do you mean by Storage disk?Storage disk may be defined as a type of hardware device that can be used to store and save digital data and applications which may be in the form of images, video, audio, etc. For example, CDs, DVDs, hard disks, pen drives, etc.
Since Hard disks generally store a large quantity of data like 120GB to 30.72 TB. But the data required to be stored is only 900 Mb,
Therefore DVD is the most accurate choice for this storage. Which stores 500Mb of data to 8.5 Gb.
Hence Amy can hand over a DVD to Bruce to copy a 900 MB file. Bruce needs to have a "DVD-RW drive" to record data on the used DVD.

Write a program code in the python programming language to find simple interest given the
formula SI = (P*R*T)/100.
Read P(Principal), R (Rate), T (Time) from the keyboard and Calculate Simple Interest (SI).
Answer:
p = float(input('Principal: '))
r = float(input('Rate: '))
t = float(input('Time: '))
si = (p * r * t) / 100
print(si)
The "float" before the input in the first 3 lines is so you're able to input decimals. If you're not using decimals, you can switch the "float" to "int". However, if you input a decimal number after you switched to int, you will receive an error
How would you describe the difference between Python and HTML? Does it make sense to have two different coding systems, or would it be better if you could create webpages with Python?
Python is used to give instructions and logic to a website while HTML is used to describe how a website would be structured and displayed in a web browser.
What is Python?Python is a high-level programming language that is designed and developed to build websites and software applications, especially through the use of dynamic semantics and data structures.
What is HTML?HTML is an acronym for hypertext markup language and it is a standard programming language that is typically used for designing, developing and creating websites.
A difference between Python and HTML is that Python is a programming language which is used to give instructions and logic to a website while HTML is a markup language that is used to describe how a website would be structured and displayed in a web browser.
In conclusion, it is much more better to have two different coding systems because each of them perform a unique task in computer programming.
