Printing an ASCII diamond with set width in python

Question

Yes, this is a homework task. But just please, if you\'re going to give me the code please tell me what you\'ve done in detail. I am extremely new to this.

So the ta

Answer 1

after your while

i=i-2
while i>0:
  print(" "*(wid-i)+"* "*i)
  i=i-1;

Answer 2

You start with i = 1 and go until i > wid to make the top. To make the bottom of the diamond, you must do the reverse of what you did for the top. The code is easy, but I won't write it unless you want me to.

Answer 3

check it out (for python 2.7x) :

---

Filled ASCII Diamond :

width = 1
width += int(raw_input('Width : '))
for i in range (1,width):
    for j in range (width,i,-1):
        print " ",
    for j in range (1,i,1):
        print " * ",
    print

for i in range (width,1,-1):
    for j in range (width,i,-1):
        print " ",
    for j in range (1,i,1):
        print " * ",
    print

This works!! But not in any Browser window . . .

Answer 4

 i=1
 j=input("ENTER NO =")
 l=0
 for i in range(i,j-((j/2)-1),1):
     print (' ' * ((j+1)/2-i)+'*' *(i*2-1))
     l=(j/2+1)
     while  (i==l):
        i=1
        for i in range(i,j,1):
            print (' ' *((i*2)-i)+'*' *(j-i*2))
        if [i==j-1]:
            l=raw_input('<press enter to exit>')       

Answer 5

I tried to explain the code with comments. I hope it helps.

wid = int(input("Width: "))

#no. of lines will be double the width
#each loop prints a line.
for i in range(wid *2):

    #first half of the diamond
    if i<=wid:
        no_of_spaces = wid - i
        no_of_stars = i
        print(" "*no_of_spaces +  "* "*no_of_stars) 

    #next half of the diamond
    else:
        no_of_spaces = i - wid
        no_of_stars = 2*wid - i
        print(" "*no_of_spaces +  "* "*no_of_stars) 

Answer 6

Since some good methods have been addressed, here are some fun little hacky solutions.

Here's one using Python 2.7 string.center just for shits.

import string    

width = int(raw_input("Width:"))

for i in range(width):
    print string.center(i * " *", width * 2 )

for i in range(width,0,-1):
    print string.center(i * " *", width * 2 )

And here's an outrageous one that ouputs using HTML to center.

file = open('file.html','w')
file.write("<div align='center'>")

for i in range(width):
    file.write(i * " *") 
    file.write("<br>")

for i in range(width,0,-1):
    file.write(i * " *")
    file.write("<br>")

file.write("</div>")
file.close() 

import webbrowser
webbrowser.open("file.html")
