Project description
Polang
Do not use this with untrusted input!
Polang is a simple arithmetic parser that compiles to Polars Expressions.
But Why?
My usecase is tabular data with a lot of columns that need transformation.
Usage
df = DataFrame({"a": np.linspace(0, 1), "b": np.sin(np.linspace(0, 1))})
df.select(polang("(sin(a) + b) * 3.2"))
Currently Supported Features
