 Input:-a list of tuples with two values (order-number: string, total-order-cost: float) each Output:- the updated list of tuples.

Condition: When b < 100, b = b + 10 where b: total-order-cost (product of the price per items and the quantity) for every tuple of (a, b) in the input list. Program: 1) With regular for-loop: # You might use list(input()) to read list from user input. inputList = [('34587',163.8),('98762',284.0),('77226',98.85),('88112',74.97)]   outputList = []   for _tuple in inputList: if (_tuple[1] < 100):      outputList.append((_tuple[0], _tuple[1]+10)) else:   outputList.append((_tuple[0],_tuple[1])) print('Updated List:',outputList)  

PS: Since tuples are immutable (cannot change it's value further) in python, we used one more list instead of replacing the given input list itself.

2) With list-comprehension:-  inputList = [('34587',163.8),('98762',284.0),('77226',98.85),('88112',74.97)]   def getUpdatedList(inputList):   return [(ele[0], ele[1]+10) if (ele[1]) < 100 else (ele[0], ele[1]) for ele in inputList]   outputList = getUpdatedList(inputTuple) print(outputList)   Or simply,   print([(ele[0], ele[1]+10) if (ele[1]) < 100 else (ele[0], ele[1]) for ele in inputList])
