我如何在 python 中编写一个 function 作为输入 2 个数字和 1 个字符串
[英]How do I write a function in python that takes as input 2 numbers, and 1 string
问题描述
I tried to do it but my code doesn't work.
我尝试这样做，但我的代码不起作用。 When I call operate(4,5,add) I have a traceback that says "name 'add' is not defined" .当我调用operate(4,5,add)时，我有一个回溯，上面写着"name 'add' is not defined" 。 Could you please help me?请你帮助我好吗？
def operate(x,y,z):
if (z == "add"):
op = x+y
print("%d + %d = %d" %(x, y, op))
elif (z == "multiply"):
op = x*y
print("%d * %d = %d" %(x, y, op))

add is not a string. add不是字符串。 'add' and "add" are strings. 'add'和"add"是字符串。 You need to call your function with operate(4, 5, 'add') or operate(4, 5, "add") .您需要使用operate(4, 5, 'add')或operate(4, 5, "add")调用您的 function。
