Study Notes
Expressions and Types in Python
- An expression is a piece of code that resolves to a value, which can be a literal or a variable.
- Expressions can use operators to compute a result, such as arithmetic operators for numeric values.
- Python has different primitive types, including strings, integers, floats, and booleans.
- Integers represent whole numbers, while floats have a decimal point and fractional part.
- Strings are snippets of text enclosed in quotation marks, and can be concatenated using the "+" operator.
- Python can determine the type of a value using the type() function.
- Different types behave differently and Python chooses operators based on types.
- Type conversion is the process of deriving a value of a different type from an existing value.
- Python automatically converts types in some cases, such as when adding an integer and a float.
- Explicit type conversion can be achieved using functions such as int(), float(), str(), and bool().
- A temperature converter program can be created using the formula C * 9/5 + 32 to convert Celsius to Fahrenheit.
- The program can be written using Python expressions, input/output statements, and type conversion functions.

Python Input, Output, Comparisons, and Boolean Logic
- Python programs are written actions to solve problems using a programming language.
- Input can be taken from the user directly or through the keyboard, file, or system.
- The input function in Python is used to get input from the user through the keyboard.
- All inputs are saved as strings, but type conversion functions like int(), float(), and str() can be used to convert them into proper data types.
- The output of a program can be displayed on the screen or console and saved in various file formats.
- Boolean data type represents binary values of true or false and is useful for representing answers to yes/no questions.
- Booleans have only two values in Python: True and False.
- Numeric and string comparisons in Python can be done using comparison operators like ==, !=, >, <, >=, and <=.
- Logical operators like and, or, and not can be used to combine and modify boolean expressions.
- Complex boolean expressions can be built using logical operators and other kinds of operators.
- Extended operator precedence in Python follows a specific order of operation for different operators.
- The next lecture will cover how to use boolean expressions to control the flow of program execution.
