Standard Library Reference

Sharpy's standard library provides Python-familiar APIs backed by .NET implementations.

Built-in Functions

Built-in functions available without any import: abs(), all(), any(), ascii(), bin(), bool(), breakpoint(), checked_int_pow(), chr(), double(), enumerate(), filter(), float(), format(), format_align(), and 32 more.

Core Types

Type	Description
list	A mutable sequence of elements, similar to Python's `list`. Supports negative indexing, slicing, and Python-style methods.
dict	A mutable mapping of keys to values, similar to Python's dict. Supports Python-style methods like get(), pop(), items(), keys(), and values().
set	A mutable set of unique elements, similar to Python's `set`. Supports set operations: union, intersection, difference, and symmetric difference.
complex	A complex number type, similar to Python's complex.

Modules

Module	Description
argparse	Command-line argument parsing.
base64	RFC 4648 base16, base32, base64, and base85 data encodings.
bisect	Array bisection algorithm for maintaining sorted lists.
calendar
collections	Specialized container datatypes: ChainMap, Counter, Deque, DefaultDict, OrderedDict.
colorsys
configparser	Configuration file parser similar to Python's configparser module.
copy
csv	CSV file reading and writing.
datetime	Classes for working with dates and times.
difflib
email	Email message creation and parsing.
fnmatch	Unix shell-style filename pattern matching.
fractions
functools	Higher-order functions and operations on callable objects.
glob	Unix shell-style pathname pattern expansion.
grapheme	Unicode grapheme cluster iteration and string width calculation.
gzip	Support for gzip compressed files.
hashlib	Secure hash and message digest algorithms.
heapq	Heap queue (priority queue) algorithm.
hmac	Keyed-hashing for message authentication (HMAC).
html	HTML processing module.
http	HTTP modules — status codes, connections, and responses.
io	Core tools for working with streams and file-like objects.
ipaddress	Functions to create and manipulate IPv4 and IPv6 addresses and networks.
itertools	Functions creating iterators for efficient looping.
json	JSON encoder and decoder.
logging	Flexible event logging system for applications.
math	Mathematical functions.
numpy	Numerical computing with multi-dimensional arrays and mathematical operations.
operator
os	Miscellaneous operating system interfaces.
pathlib	Object-oriented filesystem paths.
platform	Access to underlying platform's identifying data.
pprint
random	Generate pseudo-random numbers with various distributions.
re	Regular expression operations.
requests	HTTP library for making requests (GET, POST, PUT, DELETE, etc.).
secrets	Generate cryptographically strong random numbers suitable for managing secrets.
shlex	Simple lexical analysis of shell-style syntaxes.
shutil	Utility functions for copying and removal of files and directory trees.
socket	Low-level networking interface, similar to Python's socket module. The bulk of this module (constants, the `socket` wrapper class, the exception hierarchy, DNS helpers, and `create_connection`) is generated from `src/Sharpy.Stdlib/spy/socket_module.spy` into `SocketModule.cs`. The byte-order, inet, and `getaddrinfo` helpers below stay hand-written because they involve `short`/`byte[]` interop and runtime-constructed tuple lists that are cleaner to express directly in C#.
sqlite3	DB-API interface for SQLite databases.
statistics	Mathematical statistics functions.
string	Common string constants and operations.
struct	Interpret bytes as packed binary data.
subprocess	Subprocess management: spawn new processes, connect to their pipes, and obtain return codes.
sys	System-specific parameters and functions.
tarfile	Read and write tar archive files.
tempfile	Generate temporary files and directories.
textwrap	Text wrapping and filling.
threading	Thread-based concurrency primitives.
time	Time access and conversions.
toml	TOML configuration file parser and encoder.
unittest	The unittest module provides a Pythonic testing API that the Sharpy compiler transforms into xUnit test infrastructure during code generation.
urllib	URL parsing, quoting, and query string manipulation utilities.
uuid	UUID objects (universally unique identifiers) according to RFC 4122.
xml	XML processing module (ElementTree API).
yaml	YAML parser and emitter.
zipfile	Read and write ZIP archive files.
zlib	Compression and decompression using zlib.
