Python Division By Zero Error

you have probably seen some. There are (at least) two distinguishable kinds of errors: syntax errors and exceptions. 8.1. Syntax Errors¶ Syntax errors, also known as parsing errors, are perhaps the most common python exception message kind of complaint you get while you are still learning Python: >>> while True

and displays a little ‘arrow' pointing at the earliest point in the line where the error was detected. The error is caused by (or at least detected at) the token preceding the arrow: in the

example, the error is detected at the keyword print, since a colon (':') is missing before it. File name and line number are printed so you know where to look in case the input came from a script. 8.2. Exceptions¶ Even if a statement or expression is syntactically correct, it may cause an error when an attempt is made to execute it. Errors detected during execution are called python try except else exceptions and are not unconditionally fatal: you will soon learn how to handle them in Python programs. Most exceptions are not handled by programs, however, and result in error messages as shown here: >>> 10 * (1/0) Traceback (most recent call last): File "

Here is the question: Write the definition of in python 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 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): python division by 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[8]: 1 In [9]: 60.0 / x Out[9]: 1.935483870967742 share|improve this answer answered Sep 24 '10 at 5:37 Eli Bendersky 122k49249330 3 It might also be helpful to comment about "from future import division". mail.python.org/pipermail/tutor/2008-March/060886.html –Bill Lynch Sep 24 '10 at 6:18 Nicee thanks bro, i get it now! –1337holiday Sep 24 '10 at 22:39 Or use factor = float(sixty)/time_interval in case sixty was an already de
