Division By Zero Error In Python

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, python zerodivisionerror are perhaps the most common kind of complaint you get while you are

Python Division By Zero Exception
SyntaxError: invalid syntax The parser repeats the offending line 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 python division by zero infinity cause an error when an attempt is made to execute it. Errors detected during execution are called 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 "

Error: ZeroDivisionError: division by zero What are some ways that will prevent the user from dividing something by zero? python calculator share|improve this question edited Jun 9 '15 at 15:14 Eric Leschinski 46.3k23221190 asked Feb 28 '14 at 3:55 Dark Leviathan 381114 So this is Python 3, where input() just returns the string the user typed in, and you are trying to http://stackoverflow.com/questions/22085864/python-divide-by-0-error use exec() to evaluate the expression the user entered? Your messages should distinguish between the circumstances, otherwise you simply don't know which print statement is being executed. –holdenweb Feb 28 '14 at 4:53 I fixed that, but thanks for telling me –Dark Leviathan Feb 28 '14 at 4:58 The answers are now useless, and this whole thread is useless, and no one reading it in the future can benefit from it because you've taken the issue out of the question. Therefore, anyone who sees this in the future won't be able to know if the question is the same one they have. Please revert the question back to it's earlier state where your issue was more apparent. –JFA Mar 1 '14 at 20:23 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted You can except the ZeroDivisionError like this x = "1/0" try: exec(x) except ZeroDivisionError: print ("WARNING: Invalid Equation") If you are using Python 2.x, the input data will be evaluated here itself y = input(" >> ") so, in Python 2.x, you should be using y = raw_input(" >> ") Apart from that, you can improve this piece of code if False in [c in valid_chars for c in y]: like this valid_chars = set("0123456789-+/* \n") # We make this a set, because if not all(c in valid_chars for c in y): # c in valid_chars will be in O(1) As @gnibbler, suggested in the comments section, the same if conditio
