mas*_*lak 2 python if-statement exception python-3.x python-3.7
让我们想象一下这段代码:
try:
if condition1 and condition2: # some_exception may happen here
function1()
elif condition3 and condition4: # some_exception may happen here
function2()
else:
big
block
of
instructions
except some_exception:
big
block
of
instructions

如您所见,我重复了大量的说明(两者相同)。有没有一种避免重复的方法,但是与将代码放入函数中有所不同吗?
某种不同的逻辑还是使用finally还是尝试?我只是想不通。
在此先感谢您的帮助!
如果您不喜欢使用函数,那么如何在两个地方都设置一个变量,然后再检查它呢?
像这样:
do_stuff = False
try:
if condition1 and condition2: # some_exception may happen here
function1()
elif condition3 and condition4: # some_exception may happen here
function2()
else:
do_stuff = True
except some_exception:
do_stuff = True
...
if do_stuff:
big
block
of
instructions
