Approximating Mathematical Functions in Python

String Literals

• Python treats single quotes and double quotes equally, allowing you to embed one in the other.
• Python automatically concatenates adjacent string literals together.

Escape Sequence

• The \ character is used to escape any given character in a string, overriding its default behavior.
• Escape sequences can introduce special characters into a string.

Generators

• Generators are a simple and powerful tool for creating iterators.
• They are written like regular functions but use the yield statement to return data.
• Each time next() is called, the generator resumes where it left off, remembering all data values and the last executed statement.
• Generators can also contain return statements, which can be used to propagate exceptions.

Generator Expressions

• Generator expressions are more compact but less versatile than full generator definitions.
• They are more memory-friendly than equivalent list comprehensions.

Inheritance

• An instance of a class inherits the attributes of that class.
• Classes can also inherit attributes from other classes.

String Formatting

• There are two ways to format strings: using % operators and using the format() method.
• The % operator allows you to substitute values into a string using placeholders like %d and %s.
• The format() method allows you to specify placeholders using {0}, {1}, etc. and format specifiers like d, f, and s.

String Methods

• In Python, everything is treated as objects that can have methods and properties.
• String methods can be used to perform various operations on strings.

Defining Python Functions

• Procedures are small, dependent chunks of code that can be used to perform specific tasks.
• There are two types of procedures: functions and subroutines.
• Functions return a value, while subroutines do not.
• The advantages of using procedures include reusability, modularity, maintainability, ease of integration, and readability.

Math Module

• The math module provides various mathematical functions and constants.
• It includes functions like sqrt, pow, floor, ceil, cos, degrees, log10, log, hypot, and exp.
• The math module also defines two mathematical constants: pi and e.

Random Module

• The random module provides functions for generating random numbers.
• It includes functions like choice, randrange, randint, shuffle, and sample.
• The random module can be used to simulate random events and generate random data.
