error and exception in python code example
Example 1: python exception
try:
# Code to test / execute
print('Test')
except (SyntaxError, IndexError) as E: # specific exceptions
# Code in case of SyntaxError for example
print('Synthax or index error !')
except :
# Code for any other exception
print('Other error !')
else:
# Code if no exception caught
print('No error')
finally:
# Code executed after try block (success) or any exception (ie everytime)
print('Done')
# This code is out of try / catch bloc
print('Anything else')
Example 2: python exception
try:
# code block
except ValueError as ve:
print(ve)
Example 3: python file open try except error
def FileCheck(fn):
try:
open(fn, "r")
return 1
except IOError:
print "Error: File does not appear to exist."
return 0
result = FileCheck("testfile")
print result
