In Python, the following boilerplate code can be used to modify if code can only be executed in or out of a module context. if __name__ == '__main__' : # Anything placed here will never be executed in a module context. pass if __name__ != '__main__' : # Anything placed here will only be executed in a module context. pass
The following Python code implements the Milstein method and uses it to solve the SDE describing geometric Brownian motion defined by ... if __name__ == "__main__": ...
doctest is a module included in the Python programming language's standard library that allows the easy generation of tests based on output from the standard Python interpreter shell, cut and pasted into docstrings.
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
The uniform access principle of computer programming was put forth by Bertrand Meyer (originally in his book Object-Oriented Software Construction).It states "All services offered by a module should be available through a uniform notation, which does not betray whether they are implemented through storage or through computation."
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.

If-then-else flow diagram A nested if–then–else flow diagram. The computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
