How do I print these hash symbols using a loop?

Question

I have a loop which calculates all the prime numbers. The calculation is good but I can't figure out how to print the hash symbols before the number. For example, here is the code I have:

for num in range(MIN, rangeNumber + 1):
    # Print all prime numbers
    if num > 1:
        for i in range(2, num):
            if (num % i) == 0:
                break
        else:
            print(num)

I am trying to figure out how I can print the # sign before the numbers. Here is the output that is expected:

How can I create the for loop?

By the way: the term "hashtag" gets its name from the symbol "#" which is sometimes called "hash". The symbol itself is not called "hashtag". — mkrieger1, Oct 26 '20 at 17:26
You can call it "hash". Or "number sign". It has many names. See https://en.wikipedia.org/wiki/Number_sign — mkrieger1, Oct 26 '20 at 17:28

For a string of n #'s, just write '#' * n

Thank you for your answer. That works but it is not printing the number after the hashtags in the same line. – Arsalan Oct 26 '20 at 17:27
print('#' * n, n) – Frank Yellin Oct 26 '20 at 17:27
This works, Thanks! – Arsalan Oct 26 '20 at 17:29

Try this:

n = 3

for i in range(1, n + 1):
    print("#" * i, i)

OUTPUT:
# 1
## 2
### 3
