Study Notes

Python Programming Fundamentals

Variables: Used to store data values.
print() function: Displays output on the screen, using the syntax print("Hello, World!").
str data type: Stores sequences of characters.
input() function: Takes user input.
Lists: Ordered, mutable collections of items, created using square brackets: my_list = [1, 2, 3].
Operators: + for addition, - for subtraction, * for multiplication, / for division. Integer division (//) returns the whole number result. Modulo (%) returns the remainder. Exponentiation (**) raises a number to a power.
while loops: Used for repeated execution of code block, syntax: while x > 10:.
Comments: Used to explain code, using the # symbol.
Multi-line comments: Use triple quotes (single or double): """comment""".
append() method: Adds an item to the end of a list.
Data types:
- int (integer)
- float (floating-point number)
- complex (complex number)
Classes: Define blueprints for creating objects. Syntax class MyClass:
try...except statement: For error handling, syntax try: and except:
len() function: Returns the length of a string or list.
tuple: Immutable (unchangeable) ordered collection of items. Created using parentheses. my_tuple = (1, 2, 3)
if statements: Control program flow, use conditional expressions. if x > 5:.
else statement: Executed if the if condition is false.
for loop: Used for looping over a sequence (list, tuple, string, etc.) or a range of numbers. syntax for x in range(5):. The range() function creates a sequence of numbers.
String methods: upper(), lower(), replace(), startswith(), endswith(), strip()
in operator: Checks for membership in a sequence.
not operator: Inverts the value of a boolean expression.
set: Unordered collection of unique items. Created using curly braces my_set = {1, 2, 3}
pop() method: Removes the item at a given index from the list and returns it.
clear() method: Removes all items from a list.
