lHelp! Lists

[buran]

for t in a[i]:

Here you iterate over elements of each tuple, which are integers. So, trying t[1] raise an error
Note also that indexes start from 0, so range(len(a)) would produce error, it should be len(a)-1 which is max index.

How to do it:

my_list = [(2, 5), (1, 2), (4, 4), (2, 3), (2, 1)]
last_elements = []
for item in my_list: # pythonic way to iterate over elements of a lists
    last_elements.append(item[-1]) # python allows for negative indexes
 
print(last_elements)

or with list comprehension

my_list = [(2, 5), (1, 2), (4, 4), (2, 3), (2, 1)]
last_elements = [item[-1] for item in my_lyst]
print(last_elements)
