Dear Python friends,
Any suggestion on how to add exception and make the below program look
better , I am using Python 2.7 and Linux
------------------------------------------------------------
--------------------------------
def create_files_append():
""" """
try:
os.makedirs(QA_TEST_DIR)
except:
raise OSError("Can't create directory (%s)!" % (QA_TEST_DIR))
# Create few files and write something
for i in range(1000):
with open(os.path.join(QA_TEST_DIR,"filename%d" %i),'w') as f:
f.write("hello")
# Append the files
for i in range(1000):
with open(os.path.join(QA_TEST_DIR,"filename%d" %i),'w') as f:
f.write("hello")
return True
------------------------------------------------------------
-----------------------------------
What will be the best way to catch the exception in the above program ?
Can we replace both the with statement in the above program with something
like below
try:
for i in range(1000):
with open(os.path.join(QA_TEST_DIR,"filename%d" %i),'w') as f:
f.write("hello")
except IOError as e:
raise

Ganesh
