ZeroDivisionError: float division by zero in Python Last Updated : 22 Mar, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report In this article, we will see what is ZeroDivisionError and also different ways to fix this error. What is ZeroDivisionError?A ZeroDivisionError in Python occurs when we try to divide a number by 0. We can't divide a number by 0 otherwise it will raise an error. Let us understand it with the help of an example. In this example, we are dividing a number from 0 and we can see that it raises a ZeroDivisionError. Python a = 20 b = 0 print(a / b) How to Fix ZeroDivisionError in PythonBelow are the following ways by which we can fix ZeroDivisionError in Python:Using conditional statementUsing a try/except statementHandling user inputChecking if the value we are dividing by is not 0The ZeroDivisionError' can be fixed by using a conditional statement in which we can check whether the denominator is zero or not. If the denominator is zero then we print that the Denominator is zerootherwise normal calculation would be performed. In this another example, we are checking if the denominator is zero or not. In this case, the denominator is 0 but by using if-else condition, we will handle the error. Python a = 15.0 b = 5.0 if b == 0: print("Denominator is zero") else: print(a / b) Output3.0 Python fix ZeroDivisionError using a try/except StatementWe have used an exception handler here that sets the result to 0 if such an error occurs, and it then prints the result, which will be 0 Python a = 16.0 b = 0 try: res = a / b except ZeroDivisionError: res = 0 print(res) Output0 Handling user input with Python try/except StatementThis code takes an input number from the user and attempts to divide 'a' by it. If the user enters a valid number, it calculates and prints the result. However, it has an exception handler that catches two types of errors: ZeroDivisionError (if the user enters 0) and ValueError (if the user enters something that's not a valid number). In case of either error, it prints a message asking the user to enter a number greater than zero. Python a = 18.0 try: b = int(input('Enter a number: ')) ans = a / b print(f'Answer is: {ans}') except (ZeroDivisionError, ValueError): print('Please enter a number greater than zero') Output:Division by zero Comment More infoAdvertise with us Next Article Cannot Convert String To Float in Python M mayankvashxme4 Follow Improve Article Tags : Python Practice Tags : python Similar Reads Zerodivisionerror Integer by Zero in Python ZeroDivisionError is raised when a program attempts to perform a division operation where the denominator is zero. This situation is mathematically undefined, and Python, like many programming languages, raises an exception to signal the error.Reasons for ZerodivisionerrorThere, are some reasons tha 3 min read Convert String to Float in Python The goal of converting a string to a float in Python is to ensure that numeric text, such as "33.28", can be used in mathematical operations. For example, if a variable contains the value "33.28", we may want to convert it to a float to perform operations like addition or division. Let's explore dif 2 min read How To Fix Valueerror Exceptions In Python Python comes with built-in exceptions that are raised when common errors occur. These predefined exceptions provide an advantage because you can use the try-except block in Python to handle them beforehand. For instance, you can utilize the try-except block to manage the ValueError exception in Pyth 4 min read Cannot Convert String To Float in Python Python, a versatile and powerful programming language, is widely used for data manipulation and analysis. However, developers often encounter challenges, one of which is the "Cannot Convert String To Float" error.

Typically, a hexadecimal string is first converted to its binary representation, and then this binary representation 3 min read Division Operators in Python Division Operators allow you to divide two numbers and return a quotient, i.e., the first number or number at the left is divided by the second number or number at the right and returns the quotient.
