Hello
Here is the code I have.
I basicly want to print stars instead of numbers.
star='star'
n=5
for i in range(1,n+1):
print range(1,i+1)*star

You still have not described what your approach is and now you are showing
new requirements to display a series of stars.
Your code is:
> N=5
> For I in n:
the above line will not work it has an error n is not an iterable. So you
should probably really want:
for i in range(1, n+1)
> print range(1,i)
the above should probably be:
print range(1, i+1)
> Output should be
> 1
> 12
...
> 12345
not true as the output of the range function is a list so the output would
be:
[1]
[1, 2]
...
[1, 2, 3, 4, 5]
And then you note in your previous message what you really want is:
*
**
...
*****
How do you plan to get from lists of numbers to strings of stars?
I think you should first sit back and think about your approach to the
problem. Begin by describing what you want as output:
1 a list of something?
2. a series of printed outputs?
3. something else?
It is always best to know where you are going before you try to pack for the
trip. After all, if you plan on going to Hawaii, you will want your
swimsuit not your winter coat.
