Printing Dict as a vertical graph

[sys73r]

so I'm new to the language so I've trying to do a vertical bar graph as shown below without luck, so far the only thing i've managed to do is to make it horizontally like this:

***********
*******
****
*********
****

which i do it by
for v in d:
print(" * " * v)

however I've been trying to transpose the results but i still dont get it.

this is what i need:

d = {0: 1, 1: 10, 2: 150, 3: 200, 4:80}

|                         *
|    *                *  *
|    *          *     *  *
|    *      *   *    *   *
|    *      *   *    *   *
------------------------------
0     1    2   3   4   5

can anybody point me on the right path?

thanks!

This homework problem comes around every year. horizontal and vertical graphs.

thanks for your response, however the code mentioned in that thread does not work that's why im asking:

def ascii_barchart( lst ):
    for row in range( max(lst), 0, -1 ):
        for elem in lst:
            if elem >= row: 
                print "# ",
            else: 
                print "  ",
        print

l = [20, 10, 15, 5]
ascii_barchart( l )

that will produce an output as follows:

#
#
#
#

#
#

#
#
#
#
#

so im not looking for that.. thanks again.. let me know where i should be looking at.!

Hmm, tested mawe's code and it worked just fine ...

# mawe's vertical barschart

def ascii_barchart(lst):
    for row in range(max(lst), 0, -1):
        for elem in lst:
            if elem >= row: 
                print "# ",
            else: 
                print "  ",
        print

lst = [2, 4, 7, 10, 8, 5, 3, 1]
ascii_barchart(lst)

'''my output (python27) ...
         #             
         #             
         #  #          
      #  #  #          
      #  #  #          
      #  #  #  #       
   #  #  #  #  #       
   #  #  #  #  #  #    
#  #  #  #  #  #  #    
#  #  #  #  #  #  #  # 
'''

yeah, thanks for looking into this, in python 3 the print " ", is print(" ",) however it still gives the output as i said.. not sure what are the big differences between python 2.7 and 3 though.

see below on python 3.0

lst = [2,4,7,10,8]
def ascii_barchart(lst):
    for row in range(max(lst), 0, -1):
        for elem in lst:
            if elem >= row: 
                print("# ",)
            else: 
                print("  ",)
        print()

ascii_barchart(lst)
  
  
  
# 
  

  
  
  
# 
  

  
  
  
# 
# 

  
  
# 
# 
# 

  
  
# 
# 
#

as i said.. not sure what are the big differences between python 2.7 and 3 though.

See "Print Is A Function" here http://docs.python.org/release/3.0.1/whatsnew/3.0.html for the correct way to suppress the newline.

The correct print() function for Python3 should look like this ...

# mawe's vertical barschart for Python3

def ascii_barchart(lst):
    for row in range(max(lst), 0, -1):
        for elem in lst:
            if elem >= row: 
                print("# ", end=' ')
            else: 
                print("  ", end=' ') 
        print()

lst = [2, 4, 7, 10, 8, 5, 3, 1]
ascii_barchart(lst)

'''my output (python32) ...
         #             
         #             
         #  #          
      #  #  #          
      #  #  #          
      #  #  #  #       
   #  #  #  #  #       
   #  #  #  #  #  #    
#  #  #  #  #  #  #    
#  #  #  #  #  #  #  #

thanks man, that works:

the new documentation about print and trailing is as follows:

Old: print x, # Trailing comma suppresses newline
New: print(x, end=" ") # Appends a space instead of a newline

thank you guys!
