[英]How to skip execution if an exception occurs in Python
我正在嘗試在下面的代碼中進行異常處理。 如果有異常,它應該跳過 try 塊中的下一個語句,並應該直接轉到 except 塊並繼續循環。
from functools import reduce
def sumnumbers(list_elements):
try:
sum = reduce(lambda x, y: x + y, list_elements)
return sum
except Exception as e:
print("Error in function", list_elements)
a = [[1,2],[3,"hi"],[5,6],[7,8],[9,"hello"]]
for i in a:
try:
s = sumnumbers(i)
print("hello ", i)
except Exception as e:
print(e)
pass
實際輸出:
hello [1, 2]
Error in function [3, 'hi']
hello [3, 'hi']
hello [5, 6]
hello [7, 8]
Error in function [9, 'hello']
hello [9, 'hello']
預期輸出:
hello [1, 2]
Error in function [3, 'hi']
hello [5, 6]
hello [7, 8]
Error in function [9, 'hello']
嗨,首先,您可以查看此處以更深入地了解異常在 python 中的工作原理。
from functools import reduce
def sumnumbers(list_elements):
try:
sum = reduce(lambda x, y: x + y, list_elements)
return sum
except Exception as e:
raise Exception("Error in function", list_elements)
a = [[1,2],[3,"hi"],[5,6],[7,8],[9,"hello"]]
for i in a:
try:
s = sumnumbers(i)
print("hello ", i)
except Exception as e:
print(e)
pass
