Dictionary uses key and values.
In primes now, key(1) has the value of 2, key(2) has the value of 3...
Now to your question:
Trying to simplify this will look like this:

primes[4] = 7
primes[7] = 17

Hope this helps 😃

Answer 2

First we take the value of primes [4] that's give 7 then after again primes [7] that's give 17.

Answer 3

Dictionary has key and value
a={keys: values}
If u provide a key or an index it gives output as value
