## Exceptions and Errors Handling
|
|
|
|
When creating a program we can make mistakes that end with errors and the worst programs we make stop running,
|
|
it would be even more annoying if we could not find errors in the code that we made or what was wrong.
|
|
In simple words, errors are something that programmers avoid in making a program.
|
|
To solve this problem in python we can use `try` and `except`
|
|
|
|
Example:
|
|
|
|
```shell
|
|
>>> try:
|
|
>>> . . . print "this is not a string "+1
|
|
>>> except:
|
|
>>> . . . print "error"
|
|
error
|
|
```
|
|
and if you want to get error messages in more detail from your code, you can add arguments `except Exception as err`
|
|
|
|
```shell
|
|
>>> try:
|
|
>>> . . . print "this is not a string "+1
|
|
>>> except Exception as err:
|
|
>>> . . . print "error:\n"+str(err)
|
|
error:
|
|
cannot concatenate 'str' and 'int' objects
|
|
```
