Search Multiple Strings (from File) In A File And Print The Line

Again apologies for been noob here: Trying below code for searching multiple strings read from keywords and search in f and printing the line. It works if I have only one keyword b

Solution 1:

One of the challenges of looking for keywords is defining what you mean by keyword and how a file's contents should be parsed to find the full set of keywords. If "aa" is a keyword, should it match "aaa" or maybe ""aa()"? Can a keyword have numbers in it?

A simple solution is to say that keywords are alphabetic only and should match contiguous alphabetic strings exactly, ignoring case. Further, matches should be considered line by line, not sentence by sentence. We can use a regex to find alphabetic sequences and sets to check containment like so:

keys.txt

aa bb 

test.txt

aa is good
AA is good
bb is good
cc isnot good
aaa isnot good

test.py

import re

keyfile = "keys.txt"
testfile = "test.txt"

keys = set(key.lower() for key in 
    re.findall(r'\w+', open(keyfile , "r").readline()))

withopen(testfile) as f:
    for line in f:
        words = set(word.lower() for word in re.findall(r'\w+', line))
        if keys & words:
            print(line, end='')

Result:

aa is good
AA is good
bb is good

Add more rules for what you mean by a match and it gets more complicated.

EDIT

Suppose you have one keyword per line and you just want a substring match (that is, "aa" matches "aaa") instead of a keyword search, you could do

keyfile = "keys.txt"
testfile = "test.txt"

keys = [keyforkeyin (line.strip() for line in open(keyfile)) ifkey]

with open(testfile) as f:
    for line in f:
        forkeyin keys:
            ifkeyin line:
                print(line, end='')
                break

But I'm just guessing what your criteria are.

Solution 2:

keywords = input("Please Enter keywords path as c:/example/ \n :")
keys = open((keywords), "r").readline()
keys = keys.split(',')  # separates key strings
with open("c:/saad/saad.txt") as f:
    for line in f:
        for key in keys:
            if key.strip() in line:
                print(line)

You are reading the line in as one string. You need to make a list of each comma separated string. Then test each key for each line (removing whitespace around the key)

This is assuming your keyword file is something like: aa is good, bb is good, spam, eggs

Solution 3:

#The Easiest one...defstrsearch():

  fopen = open('logfile.txt',mode='r+')

  fread = fopen.readlines()

  x = 'Product Name'

  y = 'Problem Description'

  z = 'Resolution Summary'for line in fread:

      #print(line)if x in line:

           print(line)

       if y in line:

           print(line)

       if z in line:

           print(line)

strsearch()
