Question

I am tryint to tokenize entries from a file. However I am not able to use the line.split("") option because of unequal number of spaces between files. I am copying a few lines from my file below:

"08-09-2010 21:21:46      00:22:7f:a6:9b:69                                 -79"
"08-09-2010 21:21:46      04:4f:aa:b4:49:49                                 -79"
"08-09-2010 21:21:46      04:4f:aa:31:4e:59   tikona 18002090044            -83"
"08-09-2010 21:21:46      00:22:7f:26:9b:69   tikona 18002090044            -74"
"08-09-2010 21:21:46      04:4f:aa:34:0d:c9   tikona 18002090044            -82"
"08-09-2010 21:21:46      04:4f:aa:71:4e:59                                 -85"
"08-09-2010 21:21:46      04:4f:aa:34:21:89   tikona 18002090044            -75"
"08-09-2010 21:21:46      04:4f:aa:34:49:49   tikona 18002090044            -77"
"08-09-2010 21:21:46      04:4f:aa:74:0d:c9                                 -85"
"08-09-2010 21:22:47      18 APs were seen

I need to access the first column (which is a datetime object) the second column (00:22...) and the last column (-79 etc.). I have no trouble accessing the first and second columns, but not the last column. When I do a info=line.spilt(""), since the third column might or might no entries, I am not able to determine the token number.

How do i access the 4th column? Is there a way i can use info[i].contains(" -")?

You can rsplit to get the last value, something like “”.rsplit(” “,1)
