I.E the values are integers rather than strings. You can either correct whatever is creating the dictionary to ensure that the values have the right type, or you can cast to the correct type before calling replace. d = { 'zero': 0, 'one': 1, 'two': 2, 'three': 3 } x = 'one two three pthree two ptwo one two' #reading input from file for k, v in

You can replace items in a Python list using list indexing, a list comprehension, or a for loop. If you want to replace one value in a list, the indexing syntax is most appropriate. To replace multiple items in a list that meet a criterion, using a list comprehension is a good solution.

So for this we have to use replace function which have 3 important parameters in it. to_replace : In this we have to pass the data of any type( 

3. Strings are immutable. Hence, none of the methods you can call on a string does an in-place modification. They all return a new string, so you have to reassign the string returned by replace: for t in To_remove: for i in range (len (Originals)): Originals [i] = Originals [i].replace (t, "")
