# Python: Find the sum of the numbers among the first k with more than 2 digits

## Python Programming Puzzles: Exercise-34 with Solution

Write a Python program to find the sum of the numbers in a given list among the first k with more than 2 digits.

```Input:
[4, 5, 17, 9, 14, 108, -9, 12, 76]
Value of K: 4
Output:
0

Input:
[4, 5, 17, 9, 14, 108, -9, 12, 76]
Value of K: 6
Output:
108

Input:
[114, 215, -117, 119, 14, 108, -9, 12, 76]
Value of K: 5
Output:
331

Input:
[114, 215, -117, 119, 14, 108, -9, 12, 76]
Value of K: 1
Output:
114
```

def test(nums, k):
s = 0
for i in range(len(nums))[:k]:
if len(str(abs(nums[i])))>2:

print("Original list:",nums)
K = 4
print("Value of K:",K)
print("sum of the numbers among the first k with more than 2 digits")
print(test(nums, K))
nums = [4, 5, 17, 9, 14, 108, -9, 12 ,76]
print("\nOriginal list:",nums)
K = 6
print("Value of K:",K)
print("sum of the numbers among the first k with more than 2 digits")
print(test(nums, K))
nums = [114, 215, -117, 119, 14, 108, -9, 12 ,76]
print("\nOriginal list:",nums)
K = 5
print("Value of K:",K)
print("sum of the numbers among the first k with more than 2 digits")
print(test(nums, K))
print("\nOriginal list:",nums)
K = 1
print("Value of K:",K)
print("sum of the numbers among the first k with more than 2 digits")
print(test(nums, K))
``````

Sample Output:

```Original list: [4, 5, 17, 9, 14, 108, -9, 12, 76]
Value of K: 4
sum of the numbers among the first k with more than 2 digits
0

Original list: [4, 5, 17, 9, 14, 108, -9, 12, 76]
Value of K: 6
sum of the numbers among the first k with more than 2 digits
108

Original list: [114, 215, -117, 119, 14, 108, -9, 12, 76]
Value of K: 5
sum of the numbers among the first k with more than 2 digits
331

Original list: [114, 215, -117, 119, 14, 108, -9, 12, 76]
Value of K: 1
sum of the numbers among the first k with more than 2 digits
114
```
