Program To Print A Pyramid

Hello friends,
Today I made a new program which prints a pyramid of given length.
In my previous post a I told you about how to print a hollow pyramid, and today I made some changes in the program to print a filled pyramid.
So,  let's check out,

def pyramid(len):
    spac_len=len
    pyramid_width=1
    i=1
    while i<=len:
        #First determine spacing then pyramid width
        print " "*spac_len,str(i)*pyramid_width
        pyramid_width+=2
        spac_len-=1
        i+=1
len=input("Enter lenth of pyramid:-")
pyramid(len)

The program is somewhat complicated for a beginner but you will understand.
