Every time the number
num is produced by the random generator, the program adds 1 to the count frequency[num] which counts the number of times this particular number was generated. The test is necessary because if the key num is not already in the dictionary, the line frequency[num] = frequency[num] + 1 would raise an exception. Initialy the dictionary is empty and contains no key.
