# Write a Python Program for Linear Search # Searching an element in a list/array in python# can be simply done using \'in\' operator# Example:# if x in arr:#   print arr.index(x)  # If you want to implement Linear Search in python  # Linearly search x in arr[]# If x is present then return its location# else return -1  def search(arr, x):      for i in range(len(arr)):          if arr[i] == x:            return i      return -1
