##### Logical errors in python

A logical error in Python is an error that occurs when your code is syntactically correct, but produces the wrong output or behaves in unexpected ways because of a mistake in your logic. Logical errors can be difficult to spot because there are no syntax errors in your code, so the Python interpreter will not give you any error messages.

Here is an example of a logical error in Python:

```
def calculate_average(numbers):
total = 0
for number in numbers:
total += number
return total / len(numbers)
print(calculate_average([1, 2, 3, 4])) # Output: 2.5
```

This code contains a logical error because it calculates the average of a list of numbers by dividing the sum of the numbers by the length of the list, but it should be dividing by the length of the list minus 1. To fix the logical error, you can change the `len(numbers)`

to `len(numbers) - 1`

:

```
def calculate_average(numbers):
total = 0
for number in numbers:
total += number
return total / (len(numbers) - 1)
print(calculate_average([1, 2, 3, 4])) # Output: 3.0
```

To fix a logical error, you will need to carefully review your code and understand how it is supposed to work. It can be helpful to print out your variables or use a debugger to step through your code and see what is happening at each step.
