Page 2: Advanced Python Concepts and Code Examples

This page delves deeper into Python programming concepts, focusing on loops and conditional statements. It provides practical examples of count-controlled loops, selection statements, and conditional looping in Python.

The page begins by explaining count-controlled loops, also known as definite iteration:

Definition: Count-controlled loops are when a set of instructions is repeated a specific number of times.

Example: A for loop example is provided:

for number in range(0, 10):
    print(number)

The page then moves on to selection examples, demonstrating the use of if-elif-else statements:

Example: A speed check program is shown:

speed = int(input("Enter driver's speed: "))
if speed >= 75:
    print("Issue fine")
elif speed > 70:
    print("Warning")
elif speed == 70:
    print("Perfect speed")
else:
    print("No action")

The guide also covers conditional looping, providing two examples:

A loop that asks for the capital of France until the correct answer is given.
A loop that keeps asking for a number while it's bigger than or equal to 100.

Highlight: The page emphasizes the importance of initializing variables before using them in loops.

Finally, the page explores various forms of count-controlled iteration, demonstrating:

How to print a set number of stars
How to print the loop variable
Using start and stop values in range()
Using intervals in range()
Counting backwards
Using user input to determine the loop range

Example: A program that calculates squares up to a user-specified number:

num = int(input("Up to what number do you want the square of: "))
for counter in range(1, num+1):
    print(counter, "squared is", counter*counter)

This comprehensive guide provides a solid foundation for understanding Python data types and functions, as well as sequencing, selection, and iteration in Python, making it an invaluable resource for beginners learning Python programming.

Page 1: Python Basics and Fundamental Concepts

This page introduces essential Python coding operators and variables, along with fundamental programming concepts. It covers various operators, variable naming conventions, and key programming structures.

Vocabulary: Variables are defined as named locations in memory that store values that can change depending on conditions or information passed to the program.

The page outlines important Python operators, including:

Multiplication $*$
Addition $+$
Subtraction $-$
Division $/$
Comments $#$

It also provides guidelines for naming variables in Python, emphasizing that they can contain numbers, letters, and underscores, but cannot start with numbers or use Python functions as names.

Highlight: Python is described as powerful, simple, and flexible.

The page introduces core programming concepts:

Assignment: Giving a variable or constant a value
Input: Information fed into a system
Process: Actions performed on data while a system is running
Output: Information or data that leaves a system

It then explains three fundamental programming structures:

Sequences: Instructions carried out one after another in order
Selection: Instructions that evaluate a condition and branch to alternative paths
Iteration: A way for computer programs to repeat steps

Example: The page demonstrates how to show messages using the print() function and how to concatenate messages: print $"You are", Varnum, "years old"$

Lastly, it covers data types in Python, including:

int $var$ : Sets var to a whole number
str $var$ : Sets var to a string $text and/or numbers$
float $var$ : Sets var to a decimal number
Boolean: Used when a variable can only be True or False

Definition: Functions are defined as special keywords that perform a specific job, with print() and input() given as examples.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

Best app on earth! no words because it’s too good

Thomas R

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

Basil

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

Rohan U

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

Elisha

iOS user

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
