[Tutor] Dictionary get method

[Phil]

Thank you for reading this.

I'm working my way through a series of exercises where the author only 
provides a few solutions.

The reader is asked to modify the histogram example so that it uses the 
get method thereby eliminating the if and else statements. Histogram2 is 
my effort.

The resulting dictionary only contains the default value provided by 
"get" and I cannot see how the value can be incremented without an if 
statement.

def histogram(s):
     d = dict()
     for c in s:
         if c not in d:
             d[c] = 1
         else:
             d[c] += 1
     return d

def histogram2(s):
     d = dict()
     for c in s:
         d[c]= d.get(c, 0)

     return d

h = histogram("brontosaurs")

print h

print

print "histogram2"

h = histogram2("brontosaurs")

print h
