I'm new to Python and I'm struggling. I have a text file (*.txt) with
a couple thousand entries, each on their own line (similar to a phone
book). How do I make a script to create something like an inverted
dictionary that will allow me to call "robert" and create a new text
file of all of the lines that contain "robert"?
Thanks so much. 16 1847
Hello,
First I'm not so clear about your problem, but you can do the following
steps:
1. Transform your file into list (list1)
2. Use regex to capture 'robert' in every member of list1 and add to
list2
3. Transform your list2 into a file
pujo
import re
name = "Robert"
f = file('phonebook .txt','r')
lines = [line.rstrip("\n ") for line in f.readlines()]
pat = re.compile(name , re.I)
related_lines = [line for line in lines if pat.search(line )]
And then you write the lines in related_lines to a file. I don't really
write text to files much so, um, yeah.
OK, so my problem is I have a text file with all of these instances,
for example 5000 facts about animals. I need to go through the file
and put all of the facts (lines) that contain the word lion into a file
called lion.txt. If I come across an animal or other word for which a
file does not yet exist I need to create a file for that word and put
all instances of that word into that file. I realize that this should
probably create 30,000 files or so. Any help would be REALLY
appreciated. Thanks. Reece
I think you need to get a database. Anyways, if anything, it should
create no more than 5,000 files, since 5,000 facts shouldn't talk about
30,000 animals. There have been a few discussions about looking at
files in directories though, if you want to look at those.
I will transfer eventually use a database but is there any way for now
you could help me make the text files? Thank you so much. Reece

Oh, I seem to have missed the part saying 'or other word'. Are you
doing this for every single word in the file?
Yes, I am. Does that make it harder. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
