• @compute_property: Decorator for computing a property once and cache the result
• @static_property: Decorator for a static property (like staticmethod)
• @class_property: Decorator for a class property (like classmethod)
• call_method(obj, fnc, *args, **kwargs): Calls a method of the obj.
• default_repr_pretty: Default method to use for repr_pretty

Extensions

Extensions of Python standard functions. See lyncs_utils.extensions.

• count: See itertools.count. Adds call method
• redirect_stdout: See contextlib.redirect_stdout. Now, it redirects stdout also from C
• FreezableDict: Extension of dict. A dictionary that can be frozen at any moment.

• prod(arr): Enables math.prod for all versions of Python
• factors(n): Returns the list of factors of n
• prime_factors(n): Returns the list of prime factors of n

Functools

• is_keyword(key): Whether key can be used as a function keyword
• get_varnames(fnc): Returns the list of varnames of the function
• has_args(fnc): Whether the function uses *args
• has_kwargs(fnc): Whether the function uses **kwargs
• apply_annotations(fnc, *args, **kwargs): Applies the annotations of fnc to the respective *args, **kwargs
• select_kwargs(fnc, *args, **kwargs): Calls fnc passing *args and ONLY the applicable **kwargs

I/O

Tools for I/O. See lyncs_utils.io.

• @open_file: Decorator that opens the file (if needed) before calling the function
• read(fname/fp): Reads data from file
• write(fname/fp): Writes data into the file
• read_struct(fname/fp, format): Reads a structure from file
• write_struct(fname/fp, format, *data): Writes a structure from file
• file_size(fname/fp): Returns the file size
• to_path(fname/fp): Reaturns a Path object to the file

Logical

Functions returning or manipulating logical values (boolean). See lyncs_utils.logical.

• single_true(iter): Whether one and only one element of the list is True
• isiterable(obj): Whether the object is iteragle or not
• interactive(): Whether Python has been run in interactive mode
• version(num, pkg): Compares the version number to the one of a package
