Hi,
I keep get the response "target not found" when I updated the verify function to include 6 as an argument. Please advise why this coding isn't working. Thank you.
def linear_search(list, target): """ Returns the index position of the target if found, else returns None """
for i in range(0,len(list)): if list[i]==target: return i return None
def verify(index): if index is not None: print("Target found at index: ", index) else: print("Target not found in list")
numbers=[1,2,3,4,5,6,7,8,9,10]
result=linear_search(numbers,12) verify(result) result=linear_search(numbers,6) verify(result)

def linear_search(list, target):
for i in range(0,len(list)):
if list[i]==target:
return i
return None
def verify(index):
if index is not None:
print("Target found at index: ", index)
else:
print("Target not found in list")
numbers=[1,2,3,4,5,6,7,8,9,10]
result=linear_search(numbers,12)
verify(result)
result=linear_search(numbers,6)
verify(result)
