method

__array_ufunc__(ufunc, method, *inputs, **kwargs) → FunctionCall

</>

Allow numpy ufunc to work on Expression objects

method

__hash__() → int

</>

Make it hashable

method

__getattr__(name) → ReferenceAttr

</>

Whenever expr.attr is encountered,return a ReferenceAttr object

method

__getitem__(item) → ReferenceItem

</>

Whenever expr[item] is encountered,return a ReferenceAttr object

method

__index__()

</>

Allow Expression object to work as index or part of slice

method

__iter__()

</>

Forbiden iterating on Expression objects

If it is happening, probably wrong usage of functions/verbs

abstract method

__str__() → str

</>

Used for stringify the whole expression

function

pipda.piping.patch_classes(*classes)

</>

Patch the classes in case it has piping operator defined

For example, DataFrame.or has already been defined, so we need to patch it to force it to use ror of PipeableCall if | is registered for piping.

Parameters
  • classes — The classes to patch
function

pipda.piping.unpatch_classes(*classes)

</>

Unpatch the classes

Parameters
  • classes — The classes to unpatch
function

pipda.piping.register_piping(op)

</>

Register the piping operator for verbs

Parameters
  • op (str) — The operator used for pipingAvaiable: ">>", "|", "//", "@", "%", "&" and "^"
