def two(l): for ch in l: a=0 a+=1 if ch[a]+ch==10: print(ch and ch[a]) else: continue two([1,8,2,8]) This is the code for (Two sum )video ... Pls let me know where I went wrong.

Hey Vignesh, Thank you for reaching out! Let's examine the following screenshot, where I've copy-pasted your solution. It is important to make sure you understand what each of the variables represents. In line 1, you create a function two() which takes a single argument (of type list) that you've called l. Then, in line 2, the for-loop is constructed as follows: for ch in l: This line of code implies iteration through the list l - it picks up each number from the list. Therefore, the iterator ch is an integer. Later, in lines 5 and 6 you use ch[a]. However, since ch is an integer, it is not subscriptable. That is to say, it cannot be followed by [a]. Hope this helps! Kind regards, 365 Hristina
