Study Notes

Python programming language has various syntactical constructions, standard library functions, and interactive development environment features.
Basic programming concepts need to be learned before starting to write programs in Python.
Interactive shell, also called the REPL (Read-Evaluate-Print Loop), lets you run Python instructions one at a time and instantly shows you the results.
Data types in Python include integers, floating-point numbers, and strings.
String concatenation and replication can be performed using the + and * operators, respectively.
A variable is like a box in the computer's memory where you can store a single value.
Assignment statement is used to store values in variables.
The value of a variable can be changed by assigning a new value to it.
Variable names can be any combination of letters, numbers, and underscores, but cannot start with a number.
Python is case-sensitive, so variable names with different capitalization are considered different variables.
Variables are labeled boxes that store values in Python.
A variable is initialized the first time a value is stored in it.
Variable names should be descriptive and follow certain rules, such as starting with a lowercase letter.
The print() function displays the string value inside its parentheses on the screen.
The input() function waits for the user to type some text on the keyboard and press ENTER.
The input() function call evaluates to a string equal to the user’s text.
Expressions can always evaluate to a single value.
Comments in Python are marked with a hash symbol (#) and are ignored by the interpreter.
Blank lines can be added to make code more readable.
The file editor in Mu is used for writing entire Python programs.
Operators include +, -, *, /, //, %, and ** for math operations, and + and * for string operations
Values include 'hello', -88.8, and 5
spam is a variable and 'spam' is a string
Three data types are integers, floating-point numbers, and strings
Expressions are made up of operators, variables, and values, and they evaluate to a value
Statements include assignment statements like spam = 10
bacon contains the value 21 after the code runs
'spamspamspam' and 'spamspamspam' are the results of 'spam' + 'spamspam' and 'spam' * 3, respectively
Variable names cannot start with numbers, so 100 is an invalid variable name
The int(), float(), and str() functions can be used to convert values to their respective data types. The expression 'I have eaten ' + 99 + ' burritos.' causes an error because you cannot concatenate a string and an integer, but you can fix it by converting 99 to a string with str().
