From:http://interactivepython.org/courselib/static/pythonds/Introduction/ControlStructures.html Control Structures As we noted earlier, algorithms require two important control structures: iteration and selection. Iteration while >>>counter=1>>>whilecounter<=5:...print("Hello, world")...counter=coun...
Control structures in R allow you to control the flow of execution of the program, depending on runtime conditions. Common structures are: if, else: testing a condition for: execute a loop a fixed number of times while: execute a loop while a condition is true repeat: execute an infinite ...
In Python programming language we have the following 4 conditional control structures. Simple if-statement. If-else statement. If-elif-else statement. Nested if statement. The general syntax of a simple if statement if (<condition-1>): statement-1 statement-2 statement-p Whenever we have a co...
With a computer we do not have to worry about mistakes creeping in because of fatigue, whereas humans would need a break to stop them becoming sloppy or careless when carrying out repetitive tasks over a long period of time. Neither sequence nor selection allows us to carry out this kind ...

Install DVC and its prerequisite Python libraries. Fork and clone a GitHub repository with all the code. Download a free dataset to use in the examples. You can use any package and environment manager you want. This tutorial uses conda because it has great support for data science and machine...
This chapter, together with the next, will complete our introduction to Python. To help you understand its contents, the chapter ends with some extended examples that reiterate the points made in its shorter examples. The rest of the book has a very different flavor....

python code, while still benefiting from the parallel performance of LAMMPS. Still this comes at the cost of additional data transfer, as the LAMMPS pointers cannot be transferred this way and the linked data has to be copied instead. So copying large atomistic structures can decrease the ...
