Easy python program
<p>The user is prompted for a file, which in this case is 'histogram.txt'. The program takes each score in the text file and makes a histogram out of all the grades in the file, organizing them so that the user can see how many of each range there are. I wrote out a very simple code:</p>

<pre><code>filename = raw_input('Enter filename of grades: ')

histogram10 = 0
histogram9 = 0
histogram8 = 0
histogram7 = 0
histogram6 = 0
histogram5 = 0
histogram4 = 0
histogram3 = 0
histogram2 = 0
histogram1 = 0
histogram0 = 0

for score in open(filename):
    if score &gt;= 100:
        histogram10 = histogram10 + 1
    elif score &gt;= 90: 
        histogram9 = histogram9 + 1
    elif score &gt;= 80:
        histogram8 = histogram8 + 1
    elif score &gt;= 70:
        histogram7 = histogram7 + 1
    elif score &gt;= 60:
        histogram6 = histogram6 + 1
    elif score &gt;= 50:
        histogram5 = histogram5 + 1
    elif score &gt;= 40:
        histogram4 = histogram4 + 1
    elif score &gt;= 30:
        histogram3 = histogram3 + 1
    elif score &gt;= 20:
        histogram2 = histogram2 + 1
    elif score &gt;= 10:
        histogram1 = histogram1 + 1
    elif score &gt;= 0:
        histogram0 = histogram0 + 1

print    
print 'Grade Distribution'
print '------------------'
print '100     :',('*' * histogram10)
print '90 - 99 :',('*' * histogram9)
print '80 - 89 :',('*' * histogram8)
print '70 - 79 :',('*' * histogram7)
print '60 - 69 :',('*' * histogram6)
print '50 - 59 :',('*' * histogram5)
print '40 - 49 :',('*' * histogram4)
print '30 - 39 :',('*' * histogram3)
print '20 - 29 :',('*' * histogram2)
print '10 - 19 :',('*' * histogram1)
print '00 - 09 :',('*' * histogram0)
</code></pre>

<p>however whenever i run the program, all twenty grades get recorded onto the >= 100
like this:</p>

<pre><code>100    : ********************
90-99  : 
80-89  : 
</code></pre>

<p>etc.
... How do I make it so that the program puts the stars in the correct places?</p>
