一个b中有多个try码

Question

我的代码在try块中有问题。 为了简单起见，这是我的代码：

try:
    code a
    code b #if b fails, it should ignore, and go to c.
    code c #if c fails, go to d
    code d
except:
    pass

有可能吗？

提取（重构）语句。利用and和or的魔力来决定何时短路。

def a():
    try: # a code
    except: pass # or raise
    else: return True

def b():
    try: # b code
    except: pass # or raise
    else: return True

def c():
    try: # c code
    except: pass # or raise
    else: return True

def d():
    try: # d code
    except: pass # or raise
    else: return True

def main():   
    try:
        a() and b() or c() or d()
    except:
        pass
