This differs from the Python's implementation of the list. In a linked list, operations of reading an element, insertion, deletion in the beginning or at the end takes constant time or in Big O notation O(1), as the head and tail addresses are always available prior to the operation. ...

Part 1of the project focuses on developing a series of functions we call audio primitives. The description below lists the audio primitives every student is required to implement. Note that the primitives fall into two categories: (i) functions that generate new audio data from a given set of...
The * is used to ‘dereference the list’ (a pythonism that works in Jinja), otherwise it would take the list as a single argument. Both lists get passed to the zip filter to pair them off into a unified list (key, value, key2, value2, …). The dict function then takes this ...
PYM files have optimized read/write speeds for use in high- throughput computational projects. Finally, Scoria MDA can import other file types via MDAnalysis, both as file lists and from MDAnalysis Universe objects. Scoria stores molecular and atomic information. It tracks individual atom names, ...
