Python arrays are one of the most utilized data structures that are generally used to store multiple values of the same type in a contiguous memory location. These Python arrays simply provide efficient storage and faster operations for any numerical data. While Python does not have any built-in...
While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of Python that you might be unaware of. I find it a nice way to learn the internals of a programming language, and I believe that you'll find it ...

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 ....
Data types in Java Javahas two main data types: Primitive. Non-primitive. There are eight primitive data types: byte, short, int, long, float, double, char and bool. Byte, short, int and long all store whole numbers, although with different ranges. Float and double store fractions; char...
By wrapping the cursor.execute() in a try/except and catching the pyodbc.OperationalError (and possibly test the error details) you could recreate the connection and cursor (and then retry the request) only when needed. I also wonder if simply a simpler solution ...
