How to increment the value without using elif?

I have written the code in the following format.When i entered the age 21 then i should get -0.4.similarly when i entered the age 22 then i should get -0.3,and so on.But i do not want these much line of code.How can i improve this code.can anyone please suggest me

age=int(input("\nEnter the age :"))
a=[-0.4,-0.3,-0.2]

if age==21: 

     print("beta coefficient is ",a[0])

elif  age==22:

    print("beta coefficient is",a[1])

elif age==23:

    print("beta coefficient is ",a[2])

Heres an efficient way.

print("beta co-efficient is", a[age-21]) It's hard coded that the first value is 21, and that they increment by one, but for your case it will work.

May be you can use dictionary instead and use key to get the corresponding value as following:

a={21:-0.4, 22:-0.3, 23:-0.2}

print("beta coefficient is ",a[age])

Update:

If entered value or key does not exist in the dictionary, it will raise KeyError. In that case .get can be used with default value of None (or other value) to return when key is not found:

print("beta coefficient is ",a.get(age, None))
