list find element index
The majority of answers explain how to find a single index, but their methods do not return multiple indexes if the item is in the list multiple times. Use enumerate() : for i, j in enumerate(['foo', 'bar', 'baz']): if j == 'ba,How about the List.FindIndex Method: int index = myList.FindIndex(a => a.Prop == oProp);. This method performs a linear search; therefore, this method is an O(n) operation, where n is Count. ,print testlist.index(element). If you are not sure whether the element to look for is actually in the list, you can add a preliminary check, like if element in testlist: print testlist.index(element). or print(testlist.index(element) if element in testlis,Actually you don't have to operate with indexes here. Just iterate over words list and check if the word is listed in nasty . If it is append 'CENSORED' to the result list, else append the word itself. Or you can involve list comprehension and,Use the .IndexOf() method of the list. Specs for the method can be found on MSDN. , Take a look here: Finding index of element in a list in Haskell? i.e. use elemIndex from Data.List : http://hackage.haskell.org/packages/archive/base/4.2.0.0/doc/html/Data-List.html#v%3AelemIndex ..., scala> List("Mary", "had", "a", "little", "lamb").indexOf("little") res0: Int = 3.
