# File IO with Exception Handling

```python
try:
	with open('/File/Location/File_name.txt', mode='r') as my_file:
		print(my_file.read())

except:
	print("File does not exist: FileNotFoundError")
	
print('This line was run...')
```

## You can also have specific cases:

```python
try:
	with open('/File/Location/File_name.txt', mode='r') as my_file:
		print(my_file.read())

except TypeError:
	print("There was a type error")
	
except FileNotFoundError:
	print("File does not exist: FileNotFoundError")

except:
	print("Different types of error from the predicted ones")
	
print('This line was run...')
```

* The `except` clause will run only if there is a `TypeError` (Which is an object)

## There is also an additional clause called `finally`

```python
try:
	with open('/File/Location/File_name.txt', mode='r') as my_file:
		print(my_file.read())

except:
	print("There was an error")
	
finally:
	print('THIS WILL ALWAYS RUN')
```

* `finally` is a clause that will always run, no matter what

## If you are dealing with files there are sometimes errors that variables are not accessible

* In that case you would implement this in another `try` block
  * This can get confusing though so be careful

```python
try:
	my_file = open(file_name, mode='r')
	try:
		print(my_file.read())
	except IOError:
		print("There was an error")
	finally:
		my_file.close()
		print('The file was closed')
except:
	print('There was another error')
```

* `IOError` is a type where it handles all the file issues, such as:
  * No permission
  * Was not accessible
  * Does not have write permissions
  * Does not exist
  * Any issue with working with the file
