Loops simplify problems by allowing code to repeat without rewriting and help traverse data structures.
LESSON 3B. FOCUS: FOR LOOPS, NESTED LOOPS, TASKS AND CHALLENGES.
Introduction to, with examples, For loops. Challenges and tasks included with solutions (predict the output). Compare ‘while’ and ‘for’ loops. Use the break statement and explore how it works in different scenarios. Learn about Nested Loops. Learn about the need for initialisation (set starting value). Create your own for loops. Create the beginnings of an arithmetic quiz using a random function and for loops. Big ideas discussion: Is the universe digital. A program? Introducing Gottfried Leibniz and Konrad Zuse. Includes a suggested videos, ‘Big ideas’ discussion, and HW/research projects section.
Python programming language provides the following types of loops to handle looping requirements:
1. While
2. Do While
3. For loop
Python provides three ways for executing the loops. While all the ways provide similar basic functionality, they differ in their syntax and condition-checking time.
Loops allow blocks of code to be executed repeatedly. The two main types of loops in Python are for loops and while loops. For loops are used to iterate over an iterable object like a list or string, while while loops continue executing until a condition is no longer true. Loop control statements like continue, break, and pass can change the normal execution flow of loops. Nested loops involve having a loop inside the body of another loop.
This document provides an overview of for loops in Python programming. It discusses the anatomy of a for loop, using ranges to repeat code a set number of times, nested loops, the break statement, and examples of for loops in games and quizzes. It also provides background on the creator of Python programming language, Guido van Rossum, and discusses theories about the digital nature of the universe. Useful videos and additional reading links are included at the end.
The document provides information on various decision making and looping constructs in Python like if, else, elif, for, while loops. It explains the syntax and usage of these statements with examples. Key decision making constructs covered include if-else, if-elif-else statements. Looping constructs covered include for loops over sequences, range function to generate sequences, while loops, break and continue keywords in loops. Nested if statements and usage of else block with for and while loops are also discussed.
Primitive data types in Objective-C include int, float, double, and char. Loops like for, while, and do-while are used to repeatedly execute code. Decision making statements include if-else, if-else if-else, switch, and the conditional operator. The document discusses these programming concepts and provides examples of defining and using variables of different data types, loops, and conditional statements in Objective-C code.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

• Rust grew out of a personal project by
Mozilla employee Graydon Hoare.
• Rust is sponsored by Mozilla Research
since 2009 (announced in 2010).
33. Type Option
• Type Option represents an optional value
• Every Option is either:
• Some contains a value
or
• None does not contain any value
34. Type Option
• Option types are very common in Rust code & can be
used as:
• Initial values
• Return values for functions that are not defined over
their entire input range (partial functions)
• Return value for otherwise reporting simple errors,
where None is returned on error
• Optional struct fields
• Struct fields that can be loaned or "taken" Optional
function arguments
• Nullable pointers
• Swapping things out of difficult situations
37. If/Else Statement
• if-else in Rust is similar to other languages.
• However, the boolean condition doesn't need to be
surrounded by parentheses, &
• Each condition is followed by a block.
• if-else conditionals are expressions all branches
must return the same type.
38. [Samples] If/Else
fn main() {
let n = 5;
if n < 0 {
println!(“{} is negative”, n);
} else if n > 0 {
println!(“{} is positive”, n);
} else {
println!(“{} is zero”, n);
}
}
39. [Samples] If/Else
Add to the end of the previous example
let big_n =
if n < 10 && n > -10 {
println!(“and is a small number,
increase ten-fold”);
10 * n
} else {
println!(“and is a big number, reduce
by two”);
n / 2
};
println!(“{} -> {}”, n, big_n);
}
41. Loop in Rust
• Rust provides a loop keyword to indicate an infinite
loop.
• The break statement can be used to exit a loop at
anytime,
• The continue statement can be used to skip the rest
of the iteration & start a new one.
44. Nesting & Labels
• It is possible to break or continue outer loops when
dealing with nested loops.
• In these cases
• the loops must be annotated with some 'label
and
• the label must be passed to the break/continue
statement.
45. [Samples] Nesting & Labels
fn main() {
‘outer: loop {
println!(“Entered the outer loop”);
‘inner: loop {
println!(“Entered the inner
loop”);
break ‘outer;
}
println!(“This point will never be
reached”);
}
println!(“Exited the outer loop”);
}
47. While Statement
• The while keyword can be used to loop until a
condition is met.
• while loops are the correct choice when you’re not
sure how many times you need to loop.
48. [Samples] While Statement
fn main() {
let mut n = 1;
while n < 101 {
if n % 15 == 0 {
println!(“fizzbuzz”);
} else if n % 3 == 0 {
println!(“fizz”);
} else if n % 5 == 0 {
println!(“buzz”);
} else {
println!(“{}”, n);
}
n += 1;
} }
50. For & Range Statement
• The for in construct can be used to iterate through
an Iterator.
• One of the easiest ways to create an iterator is to use
the range notation a..b.
• This will yield values from a (inclusive) to b (exclusive)
in steps (increment) of one.
51. [Samples] For & Range
fn main() {
for n in 1..101 {
if n % 15 == 0 {
println!(“fizzbuzz”);
} else if n % 3 == 0 {
println!(“fizz”);
} else if n % 5 == 0 {
println!(“buzz”);
} else {
println!(“{}”, n);
}
}
}
57. If Let Statement
• if let is a cleaner alternative to match statement.
• It allows various failure options to be specified.
58. [Samples] If Let
fn main() {
let number = Some(7);
let letter: Option<i32> = None;
let emoticon: Option <i32> = None;
if let Some(i) = number {
println!(“Matched {:?}!”, i);
} else {
println!(“Didn’t match a number. Let’s
go with a letter!”);
};
let i_like_letters = false;
<continued…>
59. [Samples] If Let
if let Some(i) = emoticon {
println!(“Matched {:?}!”, i);
} else if i_like_letters {
println!(“Didn’t matched a number. Let’s
go with a letter!”);
} else {
println!(“I don’t like letters. Let’s go
with an emoticon :)!”);
};
}
64. Functions in Rust
• Functions are declared using the fn keyword
• Arguments are type annotated, just like variables
• If the function returns a value, the return type must be
specified after an arrow ->
• The final expression in the function will be used as
return value.
• Alternatively, the return statement can be used to return
a value earlier from within the function, even from inside
loops or if’s.
65. [Samples] Functions
• Fizz Buzz Test
• "Write a program that prints the numbers from 1 to
100.
• But for multiples of three print “Fizz” instead of the
number
• For the multiples of five print “Buzz”.
• For numbers which are multiples of both three and
five print “FizzBuzz”."
