Hello mate! in this case you can improve you code by changing this part:

if distance_to_pump <= res:
return 1
else:
return 0

In this case, you can just:

return distance_to_pump <= res

and your code will return true if the statement in the return is true, and false if not.

Hope this helps! <3

It does not feel so clear to me, if you don't have the context you won't understand what the code is for. #Explicit is better than implicit.

Hello mate! you can check if a word is a palindrome by turning the word around with slices, and then comparing it to the original word, like this:
if string == string[::-1]
print('This word is a palindrome!')
