Randomly select 0 or 1 equal number of times?

To iterate over 100 values and select randomly 0 or 1.But equal number of time

The code below prints the counts:

   import random
   c_true = 0;c_false = 0
   for i in range(100):
      a = random.getrandbits(1)
   if( a == 1):
      c_true += 1
   else:
      c_false += 1
   print "true_count:",c_true
   print "false_count:",c_false

The output is:

true_count: 56
false_count: 44

I want the counts to be equal

true_count: 50
false_count: 50

If anyone could suggest the changes to the code to obtain the desired result it will be help ful?
