In this case I chose to use the python “”” string delimiter to specify a multiline string exactly as described in the problem statement. However such a string has embedded \n characters which need to be removed. (lines 1 to 22). Lines 31 and 32 create a sequence of all the substrings of 5 consecutive digits in the above number. Lines 29 and 30 compute the product of all the numbers that form the substring. Line 28 represents the tuple of the substring followed by the product. The reduce function on lines 24 to 26 (which gets intialised with the initial data on line 33) then continuously selects the tuple with the maximum product. The final ‘[1]’ indexing operation on line 33 then just selects the product from the number product tuple selected by the earlier reduce function. Solution
