Data Type Conversion

• Python allows converting data types
• The type name is used as a function for conversion
• Example: int(2.2), float(1), str(2.2), tuple(s), list(s), set(s)

Types of Operators

• Python supports various operator types
• Arithmetic Operators (+, -, *, /, %, **, //)
• Comparison/Relational Operators (==, !=, >, <, >=, <=)
• Assignment Operators (=, +=, -=, *=, /=, %=, **=, //=)
• Logical Operators (and, or, not)
• Bitwise Operators (&, |, ^, ~)
• Python Identity Operators (is, is not)
• Membership Operators (in, not in)
• Boolean Operators (True, False)

Arithmetic Operators

• Addition (+): 10 + 20 = 30
• Subtraction (-): 20 - 10 = 10
• Multiplication (*): 10 * 20 = 200
• Division (/): 20 / 10 = 2
• Modulus (%): 22 % 10 = 2
• Exponent (**): 4 ** 2 = 16
• Floor Division (//): 9 // 2 = 4

Comparison Operators

• Equality (==): (3 == 4) is not true
• Inequality (!=): (3 != 4) is true
• Greater than (>): (3 > 4) is not true
• Less than (<): (3 < 4) is true
• Greater than or equal (>=): (3 >= 4) is not true
• Less than or equal (<=): (3 <= 4) is true

Conditional Statements (Decision Making)

• if statement: Executes code block if a condition is true.
• if-else statement: Executes one block if true, another if false.
• Nested if...else statements: if statements inside other if statements.
• if-elif statement: A multi-condition check using elif for cases after the initial if.

Loop Statements

• for loop: Repeats code a set number of times, or over an iterable object (list, tuple, etc.).
• while loop: Repeats code as long as a condition is true.
• Loop control statements (break, continue, pass): Control the flow of loops.

Useful Operators

• range(): Generates sequences of numbers, with options for start, stop, and step values.

Homework Assignments

• Various programming tasks with different requirements to utilize the learned concepts in this course. Include specific examples such as using range, list comprehensions, conditional statements, and loops. These will require writing Python code, and identifying the output values. Questions involving manipulating lists, strings, and mathematical calculations.
