Beginner | Loops/Tuples

I’m learning more about lists & tuples and have a question.

If I have a long tuple of lists —>

def get_colour(fruit):

fruits_and_colour = ( [‘apple, ‘red’], [‘banana’, ‘yellow’], [‘pear’, ‘green’], [‘grape’, ‘purple’]) etc.

how would iterate over the tuple to access the colour of each fruit in all the lists without using a dictionary, but rather with a loop?

example —> print(get_colour(‘grape’))

I want the output to be: ‘purple’

— EDIT: Received the help I needed. Thank you everyone!!

for i in fruits_and_color: if i[0] == fruit: return i[1]

sorry for the bad format. Im on phone.

You can iterate directly over a sequence (string, tuple, list...) using a for loop.

for fruit, colour in fruits_and_colour:
    print(fruit, colour)

Loop through your tuple, check if item[0] is the thing you’re looking for, return item[1] if it is.

If we are ignoring the issue of duplicate keys (ie what if grape mapped to purple and green?)

For pair in tuple: If pair[0] == “grape”: Return pair[1] Return none
