Is it possible to append spaces and a certain amount of spaces to a string?

Question

Here is my current code. The question is exactly in the title. (I'm looking to be able to align my triangle correctly)

def Triangle(height):
    if height % 2 == 0:
        print "Please enter a height that is odd"

    else:
        stringTriangle = "x"
        for x in range(height):
            print stringTriangle
            for x in range(1):
                stringTriangle+="xx"

What do you expect the output to look like? Where would you like to append spaces? — Logan Byers, Oct 05 '16 at 00:35
I'm not sure what you're doing with `range(1)` but you can do `string * iterations (int)` to achieve multiple characters. — Andrew Li, Oct 05 '16 at 00:35
Look up string formatting. http://stackoverflow.com/questions/8234445/python-format-output-string-right-alignment — justengel, Oct 05 '16 at 00:38
You can use a field width to format. Try: `'{:^30}'.format('*')` — dawg, Oct 05 '16 at 00:40
Try `print '\n'.join(['{:^20}'.format('x'*i) for i in range(1,20,2)])` — dawg, Oct 05 '16 at 00:45

To make a string containing n spaces, use " "*n. To concatenate two strings a and b, use a + b. To learn about other things that can be done with strings, see Python 2: Built-in Types: str and Other Sequence Types.

From there, you should be able to solve your homework problem by calculating how many spaces and how many asterisks you need in each line of the figure.

Is it possible to remove a certain number of spaces? For example https://repl.it/Do3C/0 in this case, how would I be able to remove 1 space from newstr? – Dqnny Oct 05 '16 at 02:55
To remove the first character, use a subsequence `s[1:]`. Read the Sequence Types link. – Damian Yerrick Oct 05 '16 at 02:57
