Zerodivisionerror float division by zero in python

ZeroDivisionError: float division | Python

In mathematics, any non-zero number either positive or negative divided by zero is undefined because there is no value. The reason is that the result of a division by zero is undefined is the fact that any attempt at a definition leads to a contradiction.

ZeroDivisionError

The super class of ZeroDivisionError is ArithmeticError. ZeroDivisionError is a built-in Python exception thrown when a number is divided by 0. This means that the exception raised when the second argument of a division or modulo operation is zero. In Mathematics, when a number is divided by a zero, the result is an infinite number. It is impossible to write an Infinite number physically. Python interpreter throws «ZeroDivisionError» error if the result is infinite number. While implementing any program logic and there is division operation make sure always handle ArithmeticError or ZeroDivisionError so that program will not terminate.

Handling ZeroDivisionError in Python

Wrap it in try-except

The above code can be reduced to:

Reproducing the error

You can solve the ZeroDivisionError by the following ways:

Wrap it in try except

Check before you do the division

The above code can be reduced to:

Different Variation

In Python, the Zero Division Error:division by zero is thrown in various forms in different contexts. They are given below:

1. ZeroDivisionError: division by zero
2. ZeroDivisionError: float division by zero
3. ZeroDivisionError: integer division or modulo by zero
4. ZeroDivisionError: long division or modulo by zero
5. ZeroDivisionError: complex division by zero

1. SyntaxError- EOL while scanning string literal
2. TypeError: Can’t convert ‘int’ object to str implicitly
3. IndentationError: expected an indented block
4. ValueError: invalid literal for int() with base 10
5. IndexError: list index out of range : Python
6. AttributeError: ‘module’ object has no attribute ‘main’
7. UnboundLocalError: local variable referenced before assignment
8. TypeError: string indices must be integers
9. FileNotFoundError: [Errno 2] No such file or directory
10. Fatal error: Python.h: No such file or directory
11. ImportError: No module named requests | Python
12. TypeError: ‘NoneType’ object is not iterable
13. SyntaxError: unexpected EOF while parsing | Python

ZeroDivisionError: float division by zero in Python

If the number (positive or negative) is divided by zero in mathematics, the output will be undefined or of no value. Similarly, if the number (integer or float) is divided by zero in Python, the interpreter will throw a “ZeroDivisionError”. To resolve this error, various solutions are used in Python, such as the “if” statement and the “try-except” block.

This blog provides the reason for the error “float division by zero” with their solutions and examples. The following aspects are followed in this article:

Reason: Dividing Floating Point Number By “0”

The prominent reason which causes this error in Python is when a user tries to divide the floating point number by “0” in a program. The error snippet is shown below:

The above snippet shows “ZeroDivisionError” because the floating point number is divided by “0”.

Solution 1: Use if-Statement

To resolve this error, you can use the “if” statement to check if the divisor is equal to “0” or not. Here is a code example:

first_number = 56.4 second_number = 0 if second_number!=0: output = first_number / second_number else: output = 0 print(output)

• The “if” statement is utilized to check whether the divisor or the number which we are dividing by is equal to zero or not.
• If the number is not equal to zero, then the “if” block statement is executed and shows the division result.
• The else block is executed when the divisor is equal to zero.

The above output shows the value “0” because the divisor number is equal to “0”.

Solution 2: Use try-except Block

Another solution to handle this particular error is using the “try-except” block in the program. Let’s understand this concept via the below-given Python program.

first_number = 56.4 second_number = 0 try: output = first_number / second_number except ZeroDivisionError: output = 0 print(output)

• The “try” block executes when the divisor is not equal to zero.
• If the dividing number/divisor is equal to zero, then the “except” block handles the “ZeroDivisionError” and assigns a “0” value to the output variable.

The output shows that the try-except block successfully resolves the stated error.

Conclusion

The “ZeroDivisionError: float division by zero” occurs when a user tries to divide a floating point number by the value “0” in Python. To resolve this error, you can use the “if-else” statement to check whether the input number is equal to zero or not before performing the calculation. The “try-except” block is also used to handle the “ZeroDivisionError” in Python programs. This blog explained how to resolve the “float division by zero” error in Python using appropriate examples.

How to fix ZeroDivisionError: float division by zero

When working with numbers in Python, you might encounter the following error:

This error occurs when you attempt to divide a floating number with zero.

Python raises the ZeroDivisionError because dividing a number with a zero returns an infinite number, which is impossible to measure in a programming language.

This tutorial will show you an example that causes this error and how to fix it

How to reproduce this error

Suppose you have two number variables where one of them is a float and the other is zero.

When you divide the float by zero as follows:

The error occurs because the y variable is zero, so the division yields an infinite number that can’t be counted.

How to fix this error

To resolve this error, you need to prevent a division by zero from happening in your code.

One way to do this is to use the if statement to check if the dividing number is zero. In this case, you have to check the value of the y variable:

Or you can also use a one-line if statement as follows:

When the value of y is zero, then set the value of z as zero too. Otherwise, divide x by y and assign the result to z .

Other similar errors

1. ZeroDivisionError: integer division by zero
2. ZeroDivisionError: integer modulo by zero
3. ZeroDivisionError: float modulo by zero

Although the error message is slightly different, all these variants are caused by the same problem: you tried to divide or modulo the number by zero.

The solution to these errors is the same, you need to prevent the numbers from being divided or reduced using a zero.

I hope this tutorial helps you solve the error. Cheers! 🙌
