製作蟒蛇3例外向後兼容

Question

什麼是落後（2.6如果可能的話），這個代碼塊的兼容語法（從PEP 3109）：

try: 
    self.spawn(pp_args) 
except DistutilsExecError as msg: 
    raise CompileError from msg 

Answer 1

這是接近你會來在python-2。 x：

try: 
    self.spawn(pp_args) 
except DistutilsExecError as msg: 
    print "DistutilsExecError : " + str(DistutilsExecError(msg)) 
    print 
    print "The above exception was the direct cause of the following exception:" 
    raise CompileError
