This answer was written in 2009, so it is a bit outdated, also it’s rather educational for understanding the problem. Best solution I’d use today would be (credits to other author here) I assume you are comparing a normal array. If not, you need to change the for loop to a for .. in loop.
Is there any function in numpy to group this array down below by the first column? I couldn’t find any good answer over the internet.. Wanted output:
I keep getting array dimension missing Planet has six dimensions, and I have an array of multiple planets
Change this to As you can see in the JavaDoc, the method does not change the argument listItems, rather it returns a new array with the remaining elements. Edit You also need to change your deletion method to So you could return the new array with the remaining elements.
Options one and two are just wrong. The first one uses the size of a pointer instead of the size of the array, so it probably won’t write to the whole array. The second uses sizeof(char*) instead of sizeof(char) so it will write past the end of the array. Option 3 is okay. You could also use this but sizeof(char) is … Read more
Try this: If that doesn’t work, then this could be the problem: Switch for
You don’t really need all that much code: Supports whitespace in elements (as long as it’s not a newline), and works in Bash 3.x. e.g.: Note: @sorontar has pointed out that care is required if elements contain wildcards such as * or ?: The sorted=($(…)) part is using the “split and glob” operator. You should … Read more
Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key. Example: Your $xml array contains an object or array at $xml->entry[$i]->source for some value of $i, and when you try to use that as an index key for $s, you get that warning. You’ll have to make sure $xml contains what you want it to … Read more
It’s easy in Python. The reason the code you’re looking at is so common is that typically, when you’re talking about a random variable in statistics, it has a range of [0,1). Think of it as a percent, if you’d like. To make this percent suitable for choosing a random element, you multiply it by … Read more
You calculate an average by adding all the elements and then dividing by the number of elements. The reason you got 68 as your result is because in your loop, you keep overwriting your average, so the final value will be the result of your last calculation. And your division and multiplication by grades.length cancel … Read more
