This method will return a string, which is the concatenation of the strings in 'sequence' by the separatorstr. Syntax Here is the syntax of the Stringjoin(sequence)method: string.join(sequence) Here, sequence- this is the sequence of elements (e.g., list, tuple) to be joined. The stri...
+operator,x + yReturns a new array with the elements from two arrays. append(x)Adds a single element to the end of the array. extend(iterable)Adds a list, array, or other iterable to the end of array. insert(i, x)Inserts an element before the given index of the array. ...
