Hello Python Friends.
I have a string array, called "line_array".
There may be up to 50 or more elements in the array.
- line_array may contain "01/04/2013 10:43 AM 17,410,217
- line_array may contain "01/25/2013 03:21 PM 17,431,230
- line_array may contain "\n"
I want to retain all elements which are valid (i.e. contains a date
So I'm using a regex search for the date value located at the start of
each element...this way
This method works really well when the regex date characters are found.
It returns the value 0 to misc_int1 because the date regex starts at 0
I was hoping the .start() method would return a -1 value for the
instance in which the regex search string is not found.
That way I could iterate through the elements and retain only the valid
However, the .start() method throws an error if the regex search string
is not found.
Your suggestions greatly appreciated!
