Study Notes
Variables
- In Python, a variable is a named storage location for values.
- Variables are created using the
=
operator, followed by a name and the value. - Variable names should start with a letter, underscore, or dollar sign.
- All subsequent characters can be letters, digits, underscores, or dollar signs.
Conditional Statements
- Conditional statements control the flow of a program based on certain conditions.
- Python uses the
if
,elif
, andelse
keywords for conditional statements. -
if
statements are used for a single condition,elif
for multiple conditions, andelse
for a default action.
Data Types
- Python supports several data types, including integers, floats, strings, and booleans.
- The
type()
function is used to check the type of a variable. - Examples of data types include:
integer = 7
,float = 3.14159
,string = "Hello, World!"
, andboolean = True
.
Operators
- Operators are symbols used to perform operations on variables.
- Examples of operators include arithmetic operators (+, -, *, /), comparison operators (==, !=, >, <), and logical operators (and, or, not).
Loops
- Loops enable the execution of repeated actions until a specific condition is met.
- Python offers several types of loops, including
while
andfor
loops. - Loops are used to iterate over sequences (such as lists or strings) or to repeat actions until a condition is met.
