Study Notes
Data Types in Python
- Python has various data types, which are automatically determined by the value assigned to a variable.
- Data types can be categorized into numeric types, sequence types, and Boolean types.
Numeric Types
- Integer: a whole number, e.g., 1000.
- Float: a number with a decimal point, e.g., 10.3.
- Numeric types can be added together, but not with non-numeric types.
Sequence Types
- String: a sequence of characters, e.g., "james" (contains 5 characters).
- String is a sequence type because it contains a sequence of individual characters.
- Strings can be added together, but not with numeric types.
Boolean Type
- Boolean: a data type that can hold only two values: True or False.
- Boolean values must be written with the first letter capitalized, e.g., True or False.
- Boolean values can be changed to a string type by assigning a string value.
Type Function
- The type function can be used to determine the type of a variable or value in Python.
- The type function returns the data type of a variable or value, e.g., integer, float, string, or Boolean.
Variable Declaration
- In Python, variable declaration does not require explicit type specification.
- Python automatically determines the data type of a variable based on the value assigned.
- Variables can be reassigned with a different data type, and Python will adjust accordingly.
Key Takeaways
- Python has various data types, including numeric, sequence, and Boolean types.
- Data types are automatically determined by the value assigned to a variable.
- Variables can be reassigned with a different data type, and Python will adjust accordingly.
- The type function can be used to determine the type of a variable or value in Python.
