如何使用 dict 优化我的代码？

Question

I have this code:

a = ""
b = ""
if a == "Hello":
    b = "Hi"
elif a == "Bye":
    b = "Good Bye"

I thought to use something like that:

mydict = {"Hello": "Hi", "Bye": "Good Bye"}

and use a lambda function which consist in looking at the keys of mydict and apply the value in function of the value of the variable a.

Di you have others ideas?

Thank you very much !

Yes. You've got the idea. Try this.

mydict = {"Hello": "Hi", "Bye": "Good Bye"}
print(mydict.get(input('Greet: ')))

No need for lambda.
