regex - Split line by +-*/() (as delimeters) without omitting them in python -

-

Good day.

I'm trying to split (tokenize) like a string

(22 + 33) * 44/300

< P> and output such as

['' ('22', '+', '33', ')', '*', '44', '/', '300 So far I tried to use 

  infix = input ("infix notation:") infix = re.split (r '[ + - / * ()] ', infix)

But it omits the delimiter and creates an element in the list.

Instead of dividing the string on the delimiter, I recommend searching only for token. 

  & gt; & Gt; & Gt; ('22', '+', '33', ')', '*', '44', 'review' '/', '300']

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
