kandi X-RAY | slice Summary
Slice is a JavaScript implementation of Python's awesome negative indexing and extended slice syntax for arrays and strings. It uses ES6 proxies to allow for an intuitive double-bracket indexing syntax which closely replicates how slices are constructed in Python. Oh, and it comes with an implementation of Python's range method too!. If you know Python, then you're probably well aware of how pleasant Python's indexing and slice syntax make working with lists and strings (and you can skip ahead to For People Who Know Python Already if you want). If not—well, you're in for a treat! Slice adds SliceArray and SliceString classes which extend the corresponding builtin types to provide a unified and concise syntax for indexing and slicing in JavaScript. For starters, negative indices can be used to count backwards from the end of an array or string. That's a convenient alternative to needing to write things like array[array.length - n], but it's really just the beginning of what Slice has to offer. Slice also introduces a double bracket indexing syntax which allows you to specify subranges of iterables by writing array[[start,stop]]. This is functionally identical to the builtin Array.slice() method, but it also works for strings and it supports assignment using the same interface. It's also possible to leave off either the start or stop parameter to have the range automatically extend to the beginning or end of the iterable. You can also add a third step parameter to your slices using the array[[start,stop,step]] syntax. That's when things get really interesting. The step parameter allows you to easily extract every Nth element from an iterable while optionally specifying a subrange at the same time.

QUESTION
Here's my csv file CSV
I'm trying to take the mean of columns "Angle Min" and "Angle Max" and then multiply every row in the resulting dataframe with the "Angle Conversion Factor" in cell D8. Likewise I want to do the same with "Torque Min" and "Torque Max" (get the mean and then multiply the resulting dataframe by the "Torque Conversion Factor" in Cell E8).
Here's my code so far:
...ANSWER
Answered 2021-Jun-15 at 21:54Your AngleConcFactor and TorqueConvFactor remain as 1x1 DataFrames in your code.
Just a slight cleanup of your function might give you what you need:

entry = [["D 300"],["D 300"],["W 200"],["D 100"]]
def bankbalance(entry):
deposits = [float(entry[ent][0][2:]) for ent in entry if ("D" in entry[ent][0])]
withdrawals = [float(entry[ent][0][2:]) for ent in entry if ("W" in entry[ent][0])]
global balance
balance = sum(deposits) - sum(withdrawals)
bankbalance(entry)
Print(f'Current balance is {balance}')
ANSWER
Answered 2021-Jun-15 at 11:02ent is not the index, it is an element of entry, so you don't need entry[ent][0][2:], what you need is ent[0][2:].

How can I do an animated shape in the form of cake or clock or circle that starts with one small slice and then over time fills the whole circle:
Is that possible with CSS? Or do I need SVG? I couldn’t find any CSS shape or mask or clipping path or anything that would work with this shape.
Thank you very much for any hints!

QUESTION
Suppose I start with a list as initial_list = [None] * 4. By setting depth = D, how can I define a routine to create a nested list of arbitrary depth in such way that each entry of the first list admits x-1 levels, being each level itself a list of other 4 elements. Something that afterwards would allow to slice data as for example myPrecious[0][0][3][0],myPrecious[3][2][1][0],... ?

QUESTION
I wrote a discord bot. "o" is first letter of play. "atla" is skip. When I wrote -o MUSIC_NAME, music is adding queue and starting to play. And when I write again, just adding queue. Everything is okay still here. When I wrote -atla. It's also working perfectly. But when I allow to changing auto music itself, it's changing music automatically. But problem is here. The end of the last music not working else if (list.length === 0) block in endHandler function. How can I fix that? Thanks for your attention.
...ANSWER
Answered 2021-Jun-15 at 15:41I'm not familiar with Discord bots but I don't think your endHandler will ever run the else if part the way it is because your code is always creating a new dispatcher when it plays the next song, but never sets up a finish handler for it.

...ANSWER
Answered 2021-Jun-15 at 15:28You can use sort -V command to consider the proper versioning of files and then invoke copy command on each file one by one or a list of files at a time.
ls | sort -V
If you're on a GNU system, you can also use ls -v. This won't work in MacOS.
QUESTION
I'm trying to solve an exercise in vanilla JS but can't figure out what I am doing wrong. I would like to change to color text to red if the product price is > 300.
In the console.log I'm getting all ok but on changeColor.style.color = "red"; I'm getting this error: TypeError: Cannot set property 'color' of undefined
Also because the page has a lazy load I could I get all price change by the time you are scrolling down?
Thanks
...ANSWER
Answered 2021-Jun-15 at 14:40 var offer = document.querySelectorAll(".grocery-item__normal-price");
var price = document.querySelectorAll(".grocery-item__normal-price");
let changePriceColor = 300;
price.forEach( (price) => {
var changeColor = price.innerHTML.slice(0,4).replace(/,/g, '');
if( changeColor > changePriceColor ) {
price.style.color = "red";
console.log(price, "true");
} else {
console.log(changeColor, "false")
}
})
}
