pandas 1.4.2

NotesParametersReturns
_replace_locals(tok: 'tuple[int, str]') -> 'tuple[int, str]'

Notes

This is somewhat of a hack in that we rewrite a string such as '@a' as '__pd_eval_local_a' by telling the tokenizer that __pd_eval_local_ is a tokenize.OP and to replace the '@' symbol with it.

Parameters

tok : tuple of int, str

ints correspond to the all caps constants in the tokenize module

Returns

tuple of int, str

Either the input or token or the replacement values

Replace local variables with a syntactically valid name.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
