logical errors(Exception)
When in the runtime an error that occurs after passing the syntax test is called exception or logical type. For example, when we divide any number by zero then the ZeroDivisionError exception is raised, or when we import a module that does not exist then ImportError is raised.
Example 1:
Python3
# initialize the amount variable marks = 10000 # perform division with 0 a = marks / 0print(a) |
Output:
In the above example the ZeroDivisionError as we are trying to divide a number by 0.
Example 2: When indentation is not correct.
Python3
if(a<3): print("gfg") |
Output:
Some of the common built-in exceptions are other than above mention exceptions are:
| Exception | Description |
|---|---|
| IndexError | When the wrong index of a list is retrieved. |
| AssertionError | It occurs when the assert statement fails |
| AttributeError | It occurs when an attribute assignment is failed. |
| ImportError | It occurs when an imported module is not found. |
| KeyError | It occurs when the key of the dictionary is not found. |
| NameError | It occurs when the variable is not defined. |
| MemoryError | It occurs when a program runs out of memory. |
| TypeError | It occurs when a function and operation are applied in an incorrect type. |

Errors and Exceptions in Python
Errors are the problems in a program due to which the program will stop the execution. On the other hand, exceptions are raised when some internal events occur which changes the normal flow of the program.
Two types of Error occurs in python.
- Syntax errors
