See the latest answer to this question here: https://docs.julialang.org/en/v1/manual/faq/#How-do-I-delete-an-object-in-memory%3F Retrieved from the docs: Julia does not have an analog of MATLAB’s clear function; once a name is defined in a Julia session (technically, in module Main), it is always present. If memory usage is your concern, you can always replace objects with ones that consume … Read more
re.match tries to match the pattern at the start of the string. You are looking for re.search, re.findall or re.finditer
Using the –save and –save-dev flags when installing will add them to the project’s package.json. This allows anyone who might develop on or use the project to install the dependencies as needed with a simple npm install command. By contrast, the -g flag is global only to your local machine.
Generalized use of global variables can make maintenance a nightmare, because they make tracing the flow of your program, and sometimes you get weird bug, because some module has read the variable and acted on its value before some other module changed the value of the variable (and this can result from inverting two import … Read more
Every “variable” in python is limited to a certain scope. The scope of a python “file” is the module-scope. Consider the following: #file test.py myvariable = 5 # myvariable has module-level scope def func(): x = 3 # x has “local” or function level scope. Objects with local scope die as soon as the function … Read more
They clutter up the global namespace and are slower to look up than local variables. First of all, having many global variables is always a bad thing because it’s easy to forget you declared a variable somewhere and accidentally re-declare it somewhere else. If your first variable was local then you don’t have a problem. … Read more
Unless you declare the function as private or fileprivate, which limit the visibility to the file or scope where it is defined, you can use it anywhere in the module if declared as internal (the default), and also from external modules if declared as public or open. However since you say that you need it … Read more
// means that the rest of the line is a comment. Global variables are generally seen as poor design, so the joke is that the best thing to do with global variables is to get rid of them.
What is the utility of having static functions in a file? You can use these functions to provide shared implementation logic to other functions within the same file. Various helper functions specific to a file are good candidates to be declared file-static. How are they different from having global functions in a file? They are … Read more
