In Python, a `ZeroDivisionError`

is raised when a division or modulo operation is attempted with a denominator or divisor of 0.

## What Causes ZeroDivisionError

A `ZeroDivisionError`

occurs in Python when a number is attempted to be divided by zero. Since division by zero is not allowed in mathematics, attempting this in Python code raises a `ZeroDivisionError`

.

## Python ZeroDivisionError Example

Here’s an example of a Python `ZeroDivisionError`

thrown due to division by zero:

```
a = 10
b = 0
print(a/b)
```

In this example, a number `a`

is attempted to be divided by another number `b`

, whose value is zero, leading to a `ZeroDivisionError`

:

```
File "test.py", line 3, in <module>
print(a/b)
ZeroDivisionError: division by zero
```

## How to Fix ZeroDivisionError in Python

The `ZeroDivisionError`

can be avoided using a conditional statement to check for a denominator or divisor of 0 before performing the operation.

The code in the earlier example can be updated to use an `if`

statement to check if the denominator is 0:

```
a = 10
b = 0
if b == 0:
print("Cannot divide by zero")
else:
print(a/b)
```

Running the above code produces the correct output as expected:

```
Cannot divide by zero
```

A try-except block can also be used to catch and handle this error if the value of the denominator is not known beforehand:

```
try:
a = 10
b = 0
print(a/b)
except ZeroDivisionError as e:
print("Error: Cannot divide by zero")
```

Surrounding the code in try-except blocks like the above allows the program to continue execution after the exception is encountered:

```
Error: Cannot divide by zero
```
