Python: Find the starting and ending position of a given value in a given array of integers, sorted in ascending order

Python Basic - 1: Exercise-76 with Solution

Write a Python program to find the starting and ending position of a given value in a given array of integers, sorted in ascending order.
If the target is not found in the array, return [0, 0].
Input: [5, 7, 7, 8, 8, 8] target value = 8
Output: [0, 5]
Input: [1, 3, 6, 9, 13, 14] target value = 4
Output: [0, 0]

Sample Solution:

Python Code:

def search_Range(array_nums, target_val):
  result_arra = []
  start_pos = 0
  end_pos = 0
  for i in range(len(array_nums)):
      if target_val == array_nums[i] and start_pos == -1:
          start_pos = i
          end_pos = i
      elif target_val == array_nums[i] and start_pos != -1:
          end_pos = i
  result_arra.append(start_pos)
  result_arra.append(end_pos)
  return result_arra
print(search_Range([5, 7, 7, 8, 8, 8], 8))
print(search_Range([1, 3, 6, 9, 13, 14], 4))
print(search_Range([5, 7, 7, 8, 10], 8))

Sample Output:

[0, 5]
[0, 0]
[0, 3]
