python - Splitting a list with a separator -

-

I wrote a function that receives two arguments: a list and one Value is present in the given list The objective of the sep function is to split the given list without the specified value in the second argument of written form and return many lists to the list. Therefore def split_list ([1,2,3,2,1], 2) ---> the result will be [[1], [3], [1]]. The spliting functionality is good, but the result holds the second value of the function in another list (SEP). I could think of the way to solve this problem. Thanks in advance 

  def split_list (l, sep): occurence = [i, enumerate in x (l) if x == sep] newlist = [] newlist.append (l [: Event for [0]]) in range (0, lane (incident)): j = i + 1 if j & lt; << Code>    
 
 
 
] in L: LL == SEP: nl.append ([]) and: # Add to last list nl [-1] .append (el) return nl

Or with your method, using the list of occurences: 

  Def split_list (L, sep): # occurences o = [i for i, calculation in n (l) if x == sep] nl = [] # first piece nl.append (l [: o [0]]) The middle slice for # (I, lane) in the # range: nl.append (l [o [i-1] + 1: o [i]] # last piece nl.append (l [o [-1] ] +1:]) back nl

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
