python - Re-scale the probabilities to make the sum of the probabilities to 1 -


this question has answer here:

i have list of probabilities follows

probability_list = [0.9, 0.8, 0.0, 0.2, 1.0]

each value represents probability of appearing given word.

e.g., 0.9 -> denotes probability of appearing word_1 0.9 e.g., 0.8 -> denotes probability of appearing word_2 0.8 , on.

now want re-scale aforementioned probability_list way sum of becomes 1.

please suggest me suitable approach this.

the easiest way sum of list , divide each element list comphrension:

total = sum(probability_list) probability_list = [i/total in probability_list]
