I do so frequently.
I often have to process files where each line is a record,
each record having a number of fields seperated with a
delimiter.
So the idiom for treating such files has become
for line in the_file:
lst = line.split(delimiter)
The problem is that the fields in lst are associated
with a number that is off by one as they are normally
counted. If I go and ask my colleague which field
contains some specific data and he answers:
the 5th, I have to remind my self I want lst[4]
This is often a cause for errors.
