If you look at the Java documentation you’ll notice the “catch” is that this function can throw a NumberFormatException, which of course you have to handle: (This treatment defaults a malformed number to 0, but you can do something else if you like.) Alternatively, you can use an Ints method from the Guava library, which in combination with Java 8’s Optional, makes … Read more
What you want to do is turn this into a grid as much as possible because grids are far easier to work with. The first thing you do is work out what column it’s in. You say you store that so it should be easier by doing a simple integer division on the x coordinate … Read more
You can make use of the reversed function for this as: Note that reversed(…) does not return a list. You can get a reversed list using list(reversed(array)).
Warning This answer will not attempt to solve this programatically … Instead it focuses on letting Matlab do the eye crossing* for you however you still need to decide how far* to cross them… * this terminology sounds wrong but I’m just going to go with it Method Simply shifting the image and subtracting it from … Read more
It is hard or impossible to detect by looking at a value.The problem is the maximum value plus even only 1 is still/again a valid value; i.e. 0. This is why most programmers avoid as much as possible, if it is actually a wrong value. For some applications, wrapping around is part of the logic … Read more
The effects of the three different methods to remove an element from a list: remove removes the first matching value, not a specific index: del removes the item at a specific index: and pop removes the item at a specific index and returns it. Their error modes are different too:
should be: You are multiplying 0.01 with the growthRates list object. Multiplying a list by an integer is valid (it’s overloaded syntactic sugar that allows you to create an extended a list with copies of its element references). Example:
shutil has many methods you can use. One of which is: Copy the contents of the file named src to a file named dst. Both src and dst need to be the entire filename of the files, including path. The destination location must be writable; otherwise, an IOError exception will be raised. If dst already exists, it will be replaced. Special files such as character or block … Read more
How do I manually throw/raise an exception in Python? Use the most specific Exception constructor that semantically fits your issue. Be specific in your message, e.g.: Don’t raise generic exceptions Avoid raising a generic Exception. To catch it, you’ll have to catch all other more specific exceptions that subclass it. Problem 1: Hiding bugs For example: … Read more
Let’s start by explaining what a tag in git is A tag is used to label and mark a specific commit in the history.It is usually used to mark release points (eg. v1.0, etc.). Although a tag may appear similar to a branch, a tag, however, does not change. It points directly to a specific commit in the history and will not … Read more
