lHelp! Lists - bwdu - Apr-12-2020 a = [(2, 5), (1, 2), (4, 4), (2, 3), (2, 1)] lastelements = [] for i in range(len(a)): for t in a[i]: lastelements.append(t[1]) print(lastelements)Guys, how can i fix this, TypeError: 'int' object is not subscriptable, for line 6? RE: lHelp! Lists - buran - Apr-12-2020 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) |
