Indentation: Python uses indentation instead of braces {} to define blocks of code, which is mandatory. Four spaces per indentation level: This is the standard practice in Python, which is used for better readability of the code. Inconsistent Indentation: There is no correct indentation such as...
There is one more important situation in which whitespace is significant in Python code. Indentation—whitespace that appears to the left of the first token on a line—has very special meaning. In most interpreted languages, leading whitespace before statements is ignored. For example, consider this...

In practice, you can often replace them with concurrent.futures, which provides a higher-level interface for both modules. On the other hand, asyncio offers a bit of a different approach to concurrency, which you’ll dive into later. Each of the corresponding types of concurrency can be ...

A program dependence graph (PDG) is a graphic representation of the data and control dependencies within a procedure. PDGs have been used to detect software plagiarism. The current methods of constructing PDGs do not include data dependence incurred by Python's dynamic reference. This paper ...
