將def clockPrint()函式放在 try-except 中時，try 塊作業正常，但 except 塊不起作用（將陳述句列印為 except 塊中的輸出）
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")
如果我嘗試clockPrint(909)根據邏輯呼叫then，它應該顯示“ Error: Invalid sentence”作為輸出，但它顯示“ TypeError: can only concatenate str (not "int") to str”作為輸出。有什么建議

你try阻止只是什么都不做。在try塊外定義函式并從該塊呼叫它。
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")

嘗試這個：
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")
