My aim is to have many inputs from a user stored in a disordered manner. So, I decided to use a `set`. The code I have so far is:

```
a = input()
b = input()
c = input()
d = input()

all = a, b, c, d
print(set(all))

```

However, I do not want to repeat `input()` several times like above. Is there a way to achieve this?
