Q8 read dates from input, one date per line.py

# Complete main() to read dates from input, one date per line. 
# Each date's format must be as follows: March 1, 1990. 
# Any date not following that format is incorrect and should beignored. 
# Use the substring() method to parse the string and extract the date.
# The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
# Ex. if input is: March 1, 1990  April 2, 1995  7/15/20  December 13, 2003  -1
# The output is: 3/1/1990  12/13/2003
