Functions in Python can be simple or extraordinarily complex. This will teach you how to write a simple Python Function example. From there you can go on to build much more complex functions. Here is an example of a Python function that multiplies an number by itself. def double(number): ...
This situation hasn’t escaped the notice of some of the biggest companies in the world (Intel, NASA, Facebook, etc.),who are all looking for Python developers. With that in mind, let’s dive into how you can prepare for Python interview questions and what those questions might look like...

List comprehension in Python provides an efficient way to create new lists without using temporary variables. It enhances readability and often performance. However, it’s important to balance its use with code readability, especially in cases of complex expressions. ...
input_size: (int) The number of frames to keep in aSequenceExample. If specified, truncation or padding may happen. Otherwise, set it to None to allow dynamic list size (recommended). context_feature_spec: (dict) Map from feature keys to `FixedLenFeature` or ...
To make you have a clear picture, I'll also give you mathematical descriptions, with several lines of code in Python. EM Algorithm Variational Inference (Variational Bayesian) GMM formula has summation (not multiplication) in distribution, and the log likelihood will then lead to complex expression...
