Python Try Finally
Try Finally
The finally
block, if specified, will be executed
regardless if the try block
raises an error or not.
Example
try:
print(x)
except:
print("Something went
wrong")
finally:
print("The 'try except' is finished")

This can be useful to close objects and clean up resources:
Example
Try to open and write to a file that is not writable:
try:
f = open("demofile.txt")
try:
f.write("Lorum Ipsum")
except:
print("Something went wrong when writing to the file")
finally:
f.close()
except:
print("Something went wrong when opening the
file")

The program can continue, without leaving the file object open.
