Strast

Strast is a versatile Python tool that transforms a string representation of a Python literal into the corresponding Python object, building upon the powerful ast module. The word "strast" also denotes "passion", reflecting our enthusiasm for data transformation.

Features

• Transform string literals to Python objects seamlessly with the power of the ast module.
• Flexible type checking to ensure data integrity.
• Supports extensibility through factory and class-based approaches.

Installation

To install Strast, use pip:

pip install strast

Usage

import strast

Function

strasts core function:

result = strast.c("{'a': 1, 'b': 2}", dict) # or strast.core.strast
print(result)
print(strast("{'a': 1, 'b': 2}", list))

Output:

{'a': 1, 'b': 2}
TypeError: Expected <class 'list'>, got <class 'dict'> instead.

Factory

strast as a closure factory function:

strast = strast.f(dict, list, tuple) # or strast.factory.strast
print(strast("{'a': 1, 'b': 2}"))
print(strast("[1, 2, 3]"))
print(strast("('a', 'b', 'c')"))

Output:

{'a': 1, 'b': 2}
[1, 2, 3]
('a', 'b', 'c')

Class-based

strast as a class:

strast = strast.S(dict) # or strast.class_based.Strast
print(strast.transform("{'a': 1, 'b': 2}"))

Output:

{'a': 1, 'b': 2}
