Python has a type of expression named a list comprehension, and a more general expression named a generator expression. [78]
Docstring documentation can also be accessed from the interpreter with the help() function, or from the shell with the pydoc command pydoc. The doctest standard module uses interactions copied from Python shell sessions into docstrings to create tests, whereas the docopt module uses them to define command-line options.
FlatBuffers is a free software library implementing a serialization format similar to Protocol Buffers, Thrift, Apache Avro, SBE, and Cap'n Proto, primarily written by Wouter van Oortmerssen and open-sourced by Google. It supports “zero-copy” deserialization, so that accessing the serialized data does not require first copying it into a ...
GDL has a Python bridge (Python code can be called from GDL; GDL can be compiled as a Python module). GDL uses Eigen (C++ library) numerical library (similar to Intel MKL) to offer high computing performance on multi-core processors. Packaged versions of GDL are available for several Linux and BSD flavours as well as macOS.
For example, if you have a list of cities in a column, firstcol,Chennai^Mumbai^Kolkata,thirdcol. CSVLoader will find that the second column has ^ character and split the column into a bulleted list like this: Chennai; Mumbai; Kolkata; The species lists on genus pages like, Hemimarginula were created using the lists feature.
