Introduction to R/Python Programming
Published in Nailong Zhang, A Tour of Data Science, 2020
One major difference between R and Python codes is that Python codes are structured with indentation. Each logical line of R/Python code belongs to a certain group. In R, we use {} to determine the grouping of statements. However, in Python we use leading whitespace (spaces and tabs) at the beginning of a logical line to compute the indentation level of the line, which is used to determine the statements’ grouping. Let’s see what happens if we remove the leading whitespace in the Python function above.

In Python, a code block is indicated by indentation. For example in the code below, we first print a message, ‘We are computing squares of numbers between 0 and 9’. Then we loop through values in the range of 0 to 9 and store it in the variable ‘i’ and also print the square of ‘i’. Finally we print the message, ‘We completed the task ...’ at the end.
Structured Programming with Python

Notice how indentation emphasizes the imbedding of the Two-way If structure into the True branch. And the indentation is mandatory! But beyond being required, indentation makes the resulting code more easily readable and its underlying structure more transparent. We consider this a positive attribute of Python.

The adopted RS with FF-WCSA scheme was implemented in PYTHON as well as the outcomes were established. One of the common-purpose programming language is Python is with a high level of abstraction. Its design philosophy prioritizes code readability through the use of substantial indentation. The adopted FF-WCSA scheme was evaluated to extant approaches such as GWO (Mirjalili, Mirjalili, and Lewis 2014), MFO (Mirjalili 2015), PSO (Pedersen and Chipperfield 2010), GWSO (Wu et al. 2012), CSA (Manimurugan et al. 2020), as well as FF (Wang et al. 2017), correspondingly. In addition, the outcomes was evaluated for different recommendations from top 10 to top 50 based on various metrics including accuracy, MAE, FDR, MARE, MSE, MSRE, RMSE, and RMSRE, correspondingly.
