[Solved] struck with raintrap in python

by


You have multiple problems with your code.

  1. Variable names could be more informative l -> left_side. This way you don’t need to have a comment on every line.
  2. You use a variable n that is not initialized to anything.
  3. Perhaps split your code into multiple functions. Then you can investigate if each function does what it should.

The first problem at hand is on line 5. You do l[0] = ... The problem is l is an empty list, so you can’t access element [0], that is why you get the error.

Instead you could append an element to l:

l.append(a[0])

0
