PIL gives a cool way to do this very simple.You can render the text onto a b/w image and convert that bitmap to a string stream replacing the black and white pixels to chars.

from PIL import Image, ImageFont, ImageDrawShowText = 'Python PIL'font = ImageFont.truetype('arialbd.ttf', 15) #load the fontsize = font.getsize(ShowText)  #calc the size of text in pixelsimage = Image.new('1', size, 1)  #create a b/w imagedraw = ImageDraw.Draw(image)draw.text((0, 0), ShowText, font=font) #render the text to the bitmapfor rownum in range(size[1]): #scan the bitmap:# print ' ' for black pixel and # print '#' for white one    line = []    for colnum in range(size[0]):        if image.getpixel((colnum, rownum)): line.append(' '),        else: line.append('#'),    print ''.join(line) 

It renders the next result:

 #######                 ##                              #######   ##  ## ##   ###           ##   ##                              ##   ###  ##  ## ##    ##           ##   ##                              ##    ##  ##  ## ##    ## ##    ## ####  ######     ####    ######       ##    ##  ##  ## ##    ##  ##  ###  ##   ###  ##   ##  ##   ###  ##      ##    ##  ##  ## ##   ##   ##  ##   ##   ##   ##  ##    ##  ##   ##      ##   ##   ##  ## ######    ##  ##   ##   ##   ##  ##    ##  ##   ##      ######    ##  ## ##         ## #    ##   ##   ##  ##    ##  ##   ##      ##        ##  ## ##         ####    ##   ##   ##  ##    ##  ##   ##      ##        ##  ## ##         ####    ##   ##   ##   ##  ##   ##   ##      ##        ##  ## ##          ##     ###  ##   ##    ####    ##   ##      ##        ##  ########             ##             ##           ###                      ##       ###

I made a little more comprehensive example with functional style.

import Image, ImageFont, ImageDrawShowText = 'Python PIL'font = ImageFont.truetype('arialbd.ttf', 15) #load the fontsize = font.getsize(ShowText)  #calc the size of text in pixelsimage = Image.new('1', size, 1)  #create a b/w imagedraw = ImageDraw.Draw(image)draw.text((0, 0), ShowText, font=font) #render the text to the bitmapdef mapBitToChar(im, col, row):    if im.getpixel((col, row)): return ' '    else: return '#'for r in range(size[1]):    print ''.join([mapBitToChar(image, c, r) for c in range(size[0])])

This is fun. I've figured out how to use PIL (the "Pillow" fork, of course) and Numpy to do this fully "vectorized", i.e. without loops:

text = "Hi there"from PIL import Image, ImageDraw, ImageFontimport numpy as npmyfont = ImageFont.truetype("verdanab.ttf", 12)size = myfont.getsize(text)img = Image.new("1",size,"black")draw = ImageDraw.Draw(img)draw.text((0, 0), text, "white", font=myfont)pixels = np.array(img, dtype=np.uint8)chars = np.array([' ','#'], dtype="U1")[pixels]strings = chars.view('U' + str(chars.shape[1])).flatten()print( "\n".join(strings))

           ##           ##                             ##    ##  ##      ##   ##                             ##    ##          ##   ##                             ##    ##  ##     ##### #####    ####   ## ##  ####    ##    ##  ##      ##   ##  ##  ##  ##  ##### ##  ##   ########  ##      ##   ##  ##  ##  ##  ##    ##  ##   ##    ##  ##      ##   ##  ##  ######  ##    ######   ##    ##  ##      ##   ##  ##  ##      ##    ##       ##    ##  ##      ##   ##  ##  ##   #  ##    ##   #   ##    ##  ##       ### ##  ##   ####   ##     ####
