"colss" a math-style expression evaluator for NumPy arrays [P]

Built a small Python library called "colss" that lets you write NumPy expressions using a shorter, more mathematical syntax.

Built using C++, OpenMP, pybind11, ExprTk, and NumPy.

Github: https://github.com/SivaPA08/colss

Example:

a = np.array([1,2,3,4]) b = np.array([4,5,6,7]) c = 2 res = colss.query("sin(a+b) + log(b)^c + 12") 

It supports:

• logical expressions
• arithmetic operations
• ternary operators
• conditional expressions

Example:

a = np.array([1,2,3,4]) res = colss.query("a > 2 ? sqrt(a) : log(a+1)") res = colss.query("if( a>b , a+1 , b-1 )") 

Compared to plain NumPy syntax, the goal is mainly:

• shorter expressions
• math-like notation
• improved readability for larger and complex formulas

Still early-stage and looking for suggestions/feedback.
