Zerodivisionerror: Division By Zero Python
vote 0 down vote favorite 1 I have a problem with this question from my professor. Here is the question: Write the definition of a function typing_speed , that receives two parameters. The first is the number of words that a person has typed (an int greater than or equal to zero) in a particular time interval. The second is the length of the time interval initialize the variable haspassedtest to true. in seconds (an int greater than zero). The function returns the typing speed of that person in words per minute (a float ). Here is my code: def typing_speed(num_words,time_interval): if(num_words >= 0 and time_interval > 0): factor = float(60 / time_interval) print factor return float(num_words/(factor)) I know that the "factor" is getting assigned 0 because its not being rounded properly or something. I dont know how to handle these decimals properly. Float isnt doing anything apparently. Any help is appreciated, thankyou. python floating-point decimal division share|improve this question edited Jun 15 at 17:05 asked Sep 24 '10 at 5:35 1337holiday 96411229 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote accepted When you call float on the division result, it's after the fact the division was treated as an integer division (note: this is Python 2, I assume). It doesn't help, what does help is initially specify the division as a floating-point division, for example by saying 60.0 (the float version of 60): factor = 60.0 / time_interval Another way would be divide 60 by float(time_interval) Note this sample interaction: In [7]: x = 31 In [8]: 60 / x Out

It is impossible to find any word division by zero in nonexistent files, so the probability should be zero. So you should write (and see next point)probability=count/num_files if numfiles else 0 // is integer division in python. you should: python3: probability=count/num_files python2 or 3: probability=float(count)/num_files see This question has already been answered.
