Stuck at get_pobs

Hello,

i stuck by implementing the function get_probs. I get the following Output:

I know i should use a sum function but i don’t understand where & and why i should use this function.

I hope somebody can explain it to me.

Thanks!

The problem was, the global variable word_l was used instead of using the values in word_count_dict to compute the denominator.
