为什么我的功能不适用于 except 块？

Question

将 def clockPrint() 函数放入 try-except 时，try 块工作正常但 except 块不起作用（将语句打印为 except 块中的输出）

import datetime
try:
    def clockPrint(sentence): 
        now = datetime.datetime.now()
        date_time = now.strftime("%H:%M:%S")
        print(date_time + " : " + sentence)
except TypeError:
    print("Error: Invalid sentence")

如果我尝试调用 clockPrint(909)，那么根据逻辑，它应该显示“Error: Invalid sentence”作为输出，但它显示“TypeError: can only concatenate str (not "int") to str”作为输出。有什么建议

Answer 1

import datetime
def clockPrint(sentence): 
    try:
        now = datetime.datetime.now()
        date_time = now.strftime("%H:%M:%S")
        print(date_time + " : " + sentence)
    except TypeError:
        print("Error: Invalid sentence")

Answer 2

试试这个：

import datetime
def clockPrint(sentence): 
    now = datetime.datetime.now()
    date_time = now.strftime("%H:%M:%S")
    try:
        print(date_time + " : " + sentence)
    except TypeError:
        print("Error: Invalid sentence")

Answer 3

你 try 块什么都不做。在 try 块外定义函数，然后从该块调用它。

import datetime

def clockPrint(sentence): 
    now = datetime.datetime.now()
    date_time = now.strftime("%H:%M:%S")
    print(date_time + " : " + sentence)

try:
    ...
    clockPrint(sentence)
    ...
except TypeError:
    print("Error: Invalid sentence")

为什么我的功能不适用于 except 块？

why my function is not working for except block?

python

function

try-except
