I suppose this is your code:
def locate_card(cards, query):
# Create a variable position with the value 0
position = 0
# Set up a loop for repetition
# Check if element at the current position match the query
if cards[position] == query:
# Answer found! Return and exit..
# Increment the position
position += 1
# Check if we have reached the end of the array
if position == len(cards):
# Number not found, return -1
while loop is set to True, it means the loop will run infinitely unless it is set to break inside itself. It can be done either by using
break inside loop for some condition, or as in this case, returning some value.
return statement when executed inside loop breaks the loop.
So, either the
query will be found in
cards list then the first
if statement will be executed and returns the position of the query and it exits the loop or it will not be found in that case we check whether we searched all positions of the
cards list (second
if statement). If we have then we return -1 and it exits the loop.
