How create variable name with other variable's value in it?

a = "Jack"
b = "Sam"

Now I want some way to create this:

c_{b value} = 10 

That means:

c_Jack = 10

And the following:

c_{a value} = 20 

That means:

c_Sam = 20

>Solution :

This is actually a bad practice to do this. You better to use a dict.

BTW, you can do this:

In [3]: a = "Jack"

In [4]: exec(f'c_{a} = 10')

In [5]: c_Jack
Out[5]: 10
