Python – How to Multiply all items in Tuple

Sometimes, while programming, we have a problem in which we might need to perform product among tuple elements. This is an essential utility as we come across product operation many times and tuples are immutable and hence required to be dealt with. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using list() + loop
The above functions can be combined to perform this task. We can employ loop to accumulate the result of product logic. The list() function is used to perform interconversions.

 # Python3 code to demonstrate working of # Tuple Elements Multiplication# Using list() + loop  # getting Product def prod(val) :     res = 1     for ele in val:         res *= ele     return res    # initializing tup test_tup = (7, 8, 9, 1, 10, 7)   # printing original tuple print("The original tuple is : " + str(test_tup))   # Tuple Elements Multiplication # Using list() + loopres = prod(list(test_tup))   # printing result print("The product of tuple elements are : " + str(res))
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The product of tuple elements are : 35280

Method #2 : Using map() + loop + list()
The combination of above functions can be used to perform this task. In this, we first convert the tuple to list, flatten it’s each list element using map(), perform product of each using loop and again employ loop for overall product of resultant list.

 # Python 3 code to demonstrate working of # Tuple Elements Multiplication# Using map() + list() + loop  # getting Product def prod(val) :     res = 1     for ele in val:         res *= ele     return res    # initializing tup test_tup = ([7, 8], [9, 1], [10, 7])   # printing original tuple print("The original tuple is : " + str(test_tup))   # Tuple Elements Multiplication# Using map() + list() + loop res = prod(list(map(prod, list(test_tup))))   # printing result print("The product of tuple elements are : " + str(res))
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The product of tuple elements are : 35280
