Question

This may be trivial for some but I have trouble looking through 2d array(?) in Python.

orderList = [ ('apples', 2.0), ('pears', 3.0), ('limes', 4.0) ]

How do I loop through this list? I’ve tried this but obviously it’s not working.

for item in orderList:
        print item;

You can use tuple unpacking to loop through everything:

for fruit, quantity in orderList:
    print 'I have', quantity, fruit + 'es'

You could also do this from inside of the for loop:

for fruit_info in orderList:
    fruit, quantity = fruit_info

    print 'I have', quantity, fruit + 'es'
