What:
oinspect.info method throws a TypeError when parsing incomplete code line, erasing partial line entry and overwriting with stacktrace with this line in oinspect:
parents_docs = parents_docs_dict.get(att_name, None)

This is triggered when composing a line involving Polars expression object, polars.expr.expr.Expr.

For example, this partial entry in a qtconsole window triggers an Exception:

pl.col("a").le(

But the proper tool tip is shown with the following:

my_expr = pl.col("a")
my_expr.le(

Since this Issue involves multiple repos, it is also reported in:

• Polars at Problem of using Expr in ipython pola-rs/polars#12394
• qtconsole at Polars code crashing mid-typing spyder-ide/qtconsole#630

Versions:

• Polars '1.35.2'
• IPython '9.7.0'
• Jupyter QtConsole 5.7.0
• Python 3.13.2
