Study Notes
Python Variables: Data Types
Numeric Data Types
-
int: whole numbers, e.g.
1,2,3, etc. -
float: decimal numbers, e.g.
3.14,-0.5, etc. -
complex: complex numbers, e.g.
3 + 4j,2 - 5j, etc.
Sequence Data Types
-
str: strings, e.g.
"hello","goodbye", etc. (can be enclosed in single quotes or double quotes) -
list: ordered collections of items, e.g.
[1, 2, 3],["a", "b", "c"], etc. -
tuple: ordered, immutable collections of items, e.g.
(1, 2, 3),("a", "b", "c"), etc.
Mapping Data Type
-
dict: unordered collections of key-value pairs, e.g.
{"name": "John", "age": 30}, etc.
Set Data Types
-
set: unordered collections of unique items, e.g.
{1, 2, 3},{"a", "b", "c"}, etc. -
frozenset: unordered, immutable collections of unique items, e.g.
frozenset({1, 2, 3}), etc.
Boolean Data Type
-
bool: boolean values, e.g.
True,False, etc.
Binary Data Type
-
bytes: binary data, e.g.
b"hello", etc. -
bytearray: mutable binary data, e.g.
bytearray(b"hello"), etc.
None Data Type
-
None: represents the absence of a value, e.g.
None, etc.
