Hi,
My work place has imposed a rules for no use of exception (catching is
allowed). If I have code like this
def f1()
if bad_thing_happen():
raise Exception('bad stuff')
...
return something
I could change it to
def f1()
if bad_thing_happen():
return [-1, None]
...
return [0, something]
f1 caller would be like this
def f1_caller():
code, result = f1(param1)
if code < 0:
return code
actual_work1()
# call f1 again
code, result = f1(param2)
if code < 0:
return code
actual_work2()
...
Are there more elegant ways than this in Python ?
Thanks,
Nick K
