Python sys 模块，exc_type() 实例源码
我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用sys.exc_type()。
def errorMsg():
try:
tb = sys.exc_info()[2]
tbinfo = traceback.format_tb(tb)[0]
theMsg = tbinfo + " \n" + str(sys.exc_type)+ ": " + str(sys.exc_value) + " \n"
arcMsg = "ArcPy ERRORS:\n" + arcpy.GetMessages(2) + "\n"
PrintMsg(theMsg, 2)
PrintMsg(arcMsg, 2)
