right, to reduce the sequence to a single subsequence example, (λx,y:x+y,[1,2,3,4,5]) (1+2)) (+3) +4). If it is initially present, it is placed before the calculated sequence item and is left as the default value when the sequence is empty.1 def Addnum (num1,num2): 2 return num1+num234 list2={1,2,3,4,5,6}5Print Reduce (Addnum, List2)Code interpretation: Calculate the value of 1+2 first, then pass the computed value as the first parameter into Addnum, the second parameter is 3, and so on.
