I am trying to implement a string list search in a context where there is no way to use something like str.startswith (If you are interested, I refer to the application data store). I would like to find every line that has a specific prefix, let them say "py".
I have comparison operators at my disposal, so I thought I could implement this as follows.
#pseudo code search = "py" search_strings_where(s > search, s < chr(ord(search[0]) + 1)
It is assumed that chr(ord(search[0]) + 1) is a character that is in the lexicographic order immediately after the first character of the search query.
The problem is that this will not work. take, for example, ord(u"β°") , which returns 8240. But inserting in chr again raises an error.
ValueError: chr() arg not in range(256)
How can i solve this?
EDIT Just found out about unichr, checking if this works. I will write an answer, if so.
