How to get sum of floats in python? - python-3.x

Question

I have a file containing a Persian sentence, then a tab, a Persian word, a tab and then an English word in each line of that. I also have a dictionary with keys and float values. I have to find the words of the file in each line that are in the dictionary, too. And then return their values. Then I have to calculate the logarithm of each word and finally calculate the sum of them for each line separately. The problem is, when I want to calculate the sum, this error occurs: TypeError: 'float' object is not iterable. How can I fix it?
import math
probabilities = {"شور": 0.02, "نمک": 0.05,"زندگی": 0.07, "غذاهای": 0.01, "غذای": 0.05}
filename = "F.txt"
for line in open(filename, encoding="utf-8"):
list_line = line.split("\t")
words = list_line[0].split()
for key, value in probabilities.items():
for word in words:
if word == key:
result = sum(float(math.log(value)))
print(word, result, end=" ")
print()
When I run it, this error appears:
Traceback (most recent call last):
File "C:\example.py", line 14, in <module>
result = sum(float(math.log(value)))
TypeError: 'float' object is not iterable

I have to calculate the sum of each line separately and have just one number for each line at last.

Your code is very wrong indeed (you may skip to point #4):
your dictionary has syntax error with the quotes
you're splitting a file handle not lines
you create a double loop to search for keys when you already have a dictionary
you just need result += float(math.log(value)), (init result to 0 outside the loop) sum is for iterables.
