I have some data (in a string) such as....
person number 1
Name: bob
Age: 50
person number 2
Name: jim
Age: 39
...all that is stored in a string. I need to pull out the names of the
different people and put them in a list or something. Any
suggestions...besides doing data.index("name")...over and over?
thanks!
Something like this works if line spacing can be depended on.
Also a good way to hide the actual format of the string from your
main program.
