Question

print和traceback混乱，即使print之前应该发生，traceback打印在上方，中间和下方。

try:
    zerrr()    
except Exception as e:
    error_json, raise_error, throw = excHandler(e, throw=False)
    # print(type(k))
    if throw:
        raise Exception(raise_error)

    error_dict = json.loads(error_json)
    print(error_dict)

try:
    typerr()    
except Exception as e:
    error_json, raise_error, throw = excHandler(e, throw=True)
    # print(type(k))
    if throw:
        # raise Exception(raise_error)
        traceback.print_exc()    
    error_dict = json.loads(error_json)
    # print(error_dict)
finally:
    # Necessary calls
    musthappen()

首次运行输出：

Traceback (most recent call last):
{'1515142630.125066': {'Line': 48, 'Error_call': "'return 1/0'", 'File': 'C:/Users/ankit.chouksey/Mariott/Pys/exclog.py', 'Error': ['ZeroDivisionError: division by zero\n'], 'Function': 'zerrr'}}
  File "C:/Users/ankit.chouksey/Mariott/Pys/exclog.py", line 69, in <module>
This is always happening irrespective of exceptions
    typerr()
  File "C:/Users/ankit.chouksey/Mariott/Pys/exclog.py", line 51, in typerr
    return 1+'a'
TypeError: unsupported operand type(s) for +: 'int' and 'str'

首次运行：
在追溯之前字典是打印的，但它正在里面打印。类似地，声明“这总是发生而不管异常”是在追溯之后打印，但它在两者之间打印。

第二次运行输出：

Traceback (most recent call last):
{'1515143476.309911': {'Line': 48, 'Error': ['ZeroDivisionError: division by zero\n'], 'Function': 'zerrr', 'Error_call': "'return 1/0'", 'File': 'C:/Users/ankit.chouksey/Mariott/Pys/exclog.py'}}
This is always happening irrespective of exceptions
  File "C:/Users/ankit.chouksey/Mariott/Pys/exclog.py", line 69, in <module>
    typerr()
  File "C:/Users/ankit.chouksey/Mariott/Pys/exclog.py", line 51, in typerr
    return 1+'a'
TypeError: unsupported operand type(s) for +: 'int' and 'str'

第二次运行 两个印刷品都在一起，但内部追溯。

我在计算机上测试了类似的代码在terminal中测试时，输出始终是正常的并且是预期的然而，当在IDE(PyCharm)中进行测试时，输出就像你所说的那样混乱 您是否正在IDE测试代码？
我认为答案可能取决于您正在使用的IDE。（IDE可能会在多线程/多处理中将消息推送到stdout？（不确定））
