By default, Python still uses timestamp-based invalidation and does not generate hash-based .pyc files at runtime. Hash-based .pyc files may be generated with py_compile or compileall. Hash-based .pyc files come in two variants: checked and unchecked. Python validates checked hash-based ....

How did Python find 5 in a dictionary containing 5.0? Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is requir...
What do you mean by data mining? Here is a data mining definition: Data mining is the process of extracting meaningful patterns, anomalies, and insights from large volumes of data. Techniques such as statistical analysis and machine learning can help you discover hidden patterns, correlations, an...
