Python中的异常处理

Python中的异常处理有多种方式，至于区别，望各位亲测

print("begin>>>>>>>>>>>>>>>>>>>>")

try:
    print("this is a string " + 3)
except:
    print("【error】")
    
print("end>>>>>>>>>>>>>>>>>>>>")

print("begin>>>>>>>>>>>>>>>>>>>>")

try:
    print("this is a string " + 3)
except Exception as r:
    print("【error】 %s" %(r))
    
print("end>>>>>>>>>>>>>>>>>>>>")

import sys

print("begin>>>>>>>>>>>>>>>>>>>>")

try:
    print("this is a string " + 3)
except:
    errMsg = sys.exc_info()
    print(errMsg)
    for item in errMsg:
        print(item )
        
print("end>>>>>>>>>>>>>>>>>>>>")

import traceback

print("begin>>>>>>>>>>>>>>>>>>>>")

try:
    print("this is a string " + 3)
except:
    traceback.print_exc()
    
print("end>>>>>>>>>>>>>>>>>>>>")
