I need some very basic help with Python 3.3. I'm trying to get a better understanding of formatting using a for loop and I want to simply print out the odd numbers from 1-20 in two columns.

Here is what I've tried:

```
for col1 in range(1,10,2):
    for col2 in range(11,20,2):
        print(col1,'\t',col2)

```

For some reason my output is very strange. The left column has the odd numbers from 1-10, but each number is listed five times before it goes to the next number

```
1   11
1   13
1   15
1   17
1   19
3   11
3   13
3   15
3   17
3   19
etc..

```

What i want is:

```
1   11
3   13
5   15
7   17
9   19

```
