more efficient print method

Expand Post »

I have an array of numbers and want to print out how many of each number there are in the array. My method works but I was wondering what a more efficient way of doing this would be. I figure a loop would work but I haven't figured out how to do it with this:

Python Syntax (Toggle Plain Text)
s='1234444432187667890000568984'
print 'I found %i:' % s.count('0'),0
print 'I found %i:' % s.count('1'),1
print 'I found %i:' % s.count('2'),2
print 'I found %i:' % s.count('3'),3
print 'I found %i:' % s.count('4'),4
print 'I found %i:' % s.count('5'),5
print 'I found %i:' % s.count('6'),6
print 'I found %i:' % s.count('7'),7
print 'I found %i:' % s.count('8'),8
print 'I found %i:' % s.count('9'),9
s='1234444432187667890000568984'
print 'I found %i:' % s.count('0'),0
print 'I found %i:' % s.count('1'),1
print 'I found %i:' % s.count('2'),2
print 'I found %i:' % s.count('3'),3
print 'I found %i:' % s.count('4'),4
print 'I found %i:' % s.count('5'),5
print 'I found %i:' % s.count('6'),6
print 'I found %i:' % s.count('7'),7
print 'I found %i:' % s.count('8'),8
print 'I found %i:' % s.count('9'),9

I did find this snippet which is fast in counting but doesn't print out like I want it to:

Python Syntax (Toggle Plain Text)
s='1234444432187667890000568984'
ans=dict((i,s.count(i)) for i in set(s))
print ans
s='1234444432187667890000568984'
ans=dict((i,s.count(i)) for i in set(s))
print ans
