Python program to find the sum of Characters ascii values in String List
Given the string list, the task is to write a Python program to compute the summation value of each character’s ASCII value.
Examples:
Input : test_list = [“geeksforgeeks”, “teaches”, “discipline”]
Output : [133, 61, 100]
Explanation : Positional character summed to get required values.Input : test_list = [“geeksforgeeks”, “discipline”]
Output : [133, 100]
Explanation : Positional character summed to get required values.
In this, we iterate each character in each string and keep on adding positional values to get its sum. The summed value is appended back to the result in a list.
Python3
# Python3 code to demonstrate working of # Characters Positions Summation in String List# Using ord() + loop # initializing listtest_list = ["geeksforgeeks", "teaches", "us", "discipline"] # printing original listprint("The original list is : " + str(test_list)) res = []for sub in test_list: ascii_sum = 0 # getting ascii value sum for ele in sub : ascii_sum += (ord(ele) - 96) res.append(ascii_sum) # printing result print("Position Summation List : " + str(res)) |
Output:
The original list is : [‘geeksforgeeks’, ‘teaches’, ‘us’, ‘discipline’]
Position Summation List : [133, 61, 40, 100]
Method 2 : Using list comprehension + sum() + ord()
In this, we get summation using sum(), ord() is used to get the ASCII positional value, and list comprehension offers one-liner solution to this problem.

Output:
The original list is : [‘geeksforgeeks’, ‘teaches’, ‘us’, ‘discipline’]
Position Summation List : [133, 61, 40, 100]
