You don’t need to use 4 spaces on your second conditional line. Maybe use: Also, don’t forget the whitespace is more flexible than you might think: Both of those are fairly ugly though. Maybe lose the brackets (the Style Guide discourages this though)? This at least gives you some differentiation. Or even: I think I prefer: Here’s … Read more
Take a look at numpy.random.rand: Docstring: rand(d0, d1, …, dn) Random values in a given shape. Create an array of the given shape and propagate it with random samples from a uniform distribution over [0, 1).
I hope this qualifies as a programming question, as in any programming tutorial, you eventually come across ‘foo’ in the code examples. (yeah, right?) what does ‘foo’ really mean? If it is meant to mean nothing, when did it begin to be used so?
Enums are classes and should follow the conventions for classes. Instances of an enum are constants and should follow the conventions for constants. So There is no reason for writing FruitEnum any more than FruitClass. You are just wasting four (or five) characters that add no information. This approach is recommended by and used in … Read more
I don’t think it will make a significant difference in compile time but #pragma once is very well supported across compilers but not actually part of the standard. The preprocessor may be a little faster with it as it is more simple to understand your exact intent. #pragma once is less prone to making mistakes and it is … Read more
It is all a matter of preference with both benefits and downfalls. Hard-coding string literals at the site of the error may be harder to maintain but it also is easier to read in my honest opinion. for example shows intent a lot better than However, the plus sides of not hard-coding the message (both 2 and 3): … Read more
Just include <stdbool.h> if your system provides it. That defines a number of macros, including bool, false, and true (defined to _Bool, 0, and 1 respectively). See section 7.16 of C99 for more details.
The first way is easier to maintain. Each declaration is a single statement on a single line, so you can easily add, remove, and reorder the declarations. With the second way, it is annoying to remove the first or last declaration because they start from the var keyword and finish with the semicolon respectively. Every time you … Read more
Formats Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in this blog post. Note that the reST is recommended by the PEP 287 There follows the main used formats … Read more
There are some (rare) cases where goto can actually improve readability. In fact, the documentation you linked to lists two examples: A common use of goto is to transfer control to a specific switch-case label or the default label in a switch statement. The goto statement is also useful to get out of deeply nested … Read more
