The pypa sample project contains a complete, easily modifiable template setup.py that demonstrates a large range of capabilities setup-tools has to offer.
Most command line tools rely on arguments passed to the program upon its execution. Instead of prompting for input, these programs expect data or specific flags (which become booleans) to be set. This allows both the user and other programs to run the Python file passing it data as it starts. This s...
A set contains only one copy of each distinct element. Unlike some other programming languages, base R does not have a dedicated data type for sets. Instead, R treats a vector like a set by taking only its distinct elements. This applies to the set operators, setdiff, intersect, union, setequal an...

MySQL has some special names called reserved words. A reserved word can be used as an identifier for a table, column, etc. only if it's wrapped in backticks (`), otherwise it will give rise to an error. To avoid such errors, either don't use reserved words as identifiers or wrap the offending ident...
