how to sum float numbers

P: 3
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 in 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?

  1. import math
  3. probabilities = {"شور": 0.02, "نمک": 0.05,"زندگی": 0.07, "غذاهای": 0.01, "غذای": 0.05}
  5. filename = "F.txt"
  7. for line in open(filename, encoding="utf-8"):
  8.     list_line = line.split("\t")
  9.     words = list_line[0].split()
  10.     for key, value in probabilities.items():
  11.         for word in words:
  12.             if word == key:
  13.                 result = sum(math.log(value))
  14.                 print(word, result, end=" ")
  15.     print()
The file:

If you omit sum from the code and then run it, you can see how the numbers are located.

Hint: I want to sum the words of each line separately.
for example if I have 4 sentences, I should have 4 numbers finally.

Your dictionary is incorrect. Check the quotation marks. As for the error, there is no way to tell where it is coming from unless you include the complete error message.
