Python – Cubes Product in list

  • Last Updated : 27 Feb, 2020

Python being the language of magicians can be used to perform many tedious and repetitive tasks in a easy and concise manner and having the knowledge to utilize this tool to the fullest is always useful. One such small application can be finding product of cubes of list in just one line. Let’s discuss certain ways in which this can be performed.

Method #1 : Using reduce() + lambda
The power of lambda functions to perform lengthy tasks in just one line, allows it combined with reduce which is used to accumulate the subproblem, to perform this task as well. Works with only Python 2.

# Python code to demonstrate 
# Cubes Product in list
# using reduce() + lambda
  
# initializing list
test_list = [3, 5, 7, 9, 11]
  
# printing original list 
print ("The original list is : " + str(test_list))
  
# using reduce() + lambda
# Cubes Product in list
res = reduce(lambda i, j: i * j*j * j, [test_list[:1][0]**3]+test_list[1:])
  
# printing result
print ("The product of cubes of list is : " + str(res))
Output :



The original list is : [3, 5, 7, 9, 11]
The product of cubes of list is : 1123242379875

 

Method #2 : Using map() + loop
The similar solution can also be obtained using the map function to integrate and external product function to perform the product of the cubed number.




# Python3 code to demonstrate 
# Cubes Product in list
# using loop + max()
  
# getting Product 
def prod(val) : 
    res = 1
    for ele in val: 
        res *= ele 
    return res 
  
# initializing list
test_list = [3, 5, 7, 9, 11]
  
# printing original list 
print ("The original list is : " + str(test_list))
  
# using loop + max()
# Cubes Product in list
res = prod(map(lambda i : i * i * i, test_list))
  
# printing result
print ("The product of cubes of list is : " + str(res))
Output :
The original list is : [3, 5, 7, 9, 11]
The product of cubes of list is : 1123242379875
