Introduction to python core data types

Number: int, long, float, complex, bool character: str, unicode list: list Dictionary: dict tuples: tuple file: file other types: set, frozenset, class, None other file tools: pipelines, first-in-first-out pipelines ),... overview

Other file tools: pipelines, first-in-first-out pipelines, and sockets)

Type conversion Non-character --> character

Project	Operation
Str ()	Same as print
Repr ()	Object, but most of them use eval (repr (object) = object
Format ()	Format (value [, format_spec])

Convertible non-value --> value

Project	Operation
Int ()	Convert to integer
Float ()	Convert to floating point

Serialization

Project	Operation
List ()	String conversion to list
Tuple ()	Convert string to tuples
Set ()	String to set
Frozenset ()	Converts a string to an unchangeable set.
Dict ()	Create a dictionary based on the list of (key, value) tuples

Character and ASCII conversion

chr() <==> ord()

Hexadecimal conversion

Project	Operation
Bin	Converts an integer to a binary string.
Oct	Converts an integer to an octal string.
Hex	Converts an integer to a hexadecimal string.
Eval	Convert to numeric
