#what do you think will be the output of the following code: 

mastr = "hello123" # string is just a list of characters 
number = [1,2,3,4,5,6]
print (number)
shoppinglist = ['shoes','bags','pants','shirts])

#how to add an item at the end of the list 

shopping. append('ties')
print (shoppinglist)
for martin in shoppinglist
