# 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

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

```def tips_check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))
```

Output:

```True
```
