Doubt regarding a code
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,
