Python: Sum of the numbers in a list between the indices of a specified range

Python List: Exercise - 128 with Solution

Write a Python program to calculate the sum of the numbers in a list between the indices of a specified range.

Sample Solution:

Python Code:

def sum_Range_list(nums, m, n):                                                                                                                                                                                                
    sum_range = 0                                                                                                                                                                                                         
    for i in range(m, n+1, 1):                                                                                                                                                                                        
        sum_range += nums[i]                                                                                                                                                                                                  
    return sum_range   

nums = [2,1,5,6,8,3,4,9,10,11,8,12]
print("Original list:")
print(nums)
m = 8
n = 10
print("Range:",m,",",n) 
print("\nSum of the specified range:")
print(sum_Range_list(nums, m, n))

Sample Output:

Original list:
[2, 1, 5, 6, 8, 3, 4, 9, 10, 11, 8, 12]
Range: 8 , 10

Sum of the specified range:
29

Python: Tips of the Day

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
