Python's standard library has (to take three examples) threads, processes, and
datetime functions. Meanwhile, PyQt has QThread, QProcess, and QDateTime.
Does this redundancy exist for C++ programmers who are programming Qt directly,
and who may lack a standard C++ library with these features? Are the Python
wrappers simply provided for completeness, or do these libraries truly function
differently? When writing a PyQt application, how does one choose between the
standard library and the PyQt library?
