**Question**:

- Write a program, which will find all such numbers between 1000 and 3000 (both included) such that each digit of the number is an even number.
- The numbers obtained should be printed in a comma-separated sequence on a single line.

**Hints**:

In case of input data being supplied to the question, it should be assumed to be a console input.

**Solution:**

```
values = []
for i in range(1000, 3001):
s = str(i)
if (int(s[0])%2==0) and (int(s[1])%2==0) and (int(s[2])%2==0) and (int(s[3])%2==0):
values.append(s)
print(",".join(values))
```
