I created this script I tried various things here and nothing helped so I would like to contact you as more experienced people
basically the script principle what does it do?
the code I put here does this
input
1:1:1
output
1:1:1 this is text from file
it works great but if i want to search for two results so it doesn't work here i try it in several ways
the problem is that I want to look for two things at the same time
input 1:1:1 === 4:1:2===0---0
I'll do a split here
split ("===") [0]
split ("===") [1]
split ("===") [2]
and the output I'm looking for is
1: 1: 1 this is text from file 4: 1: 2 this is next text resolut 0 --- 0
from the file from which it takes data looks something like this
"numberssearch.txt"
1:1:1===4:1:2===0---0
1:1:1===4:2:3===-1----1
1:1:1===4:3:4===-2----2
1:1:1===4:4:5===-3----3
1:1:1===4:5:6===-4----4
1:1:1===4:6:7===-5----5
and this is what the file from which it takes data looks like
"book.txt"
1:1:1 text1
1:1:2 text2
1:1:3 text3
1:1:4 text4
1:1:5 text5
1:1:6 text6
1:1:7 text7
ect...
this is code
with open ("numberssearch.txt") as f:
unsolved = set (f.read (). split ())
for unsolved_elem in unsolved:
userinput = unsolved_elem
file = open("book.txt",encoding='ISO-8859-1')
lines = file.readlines()
for line in lines:
words = line.split()
unsolved_elem = unsolved_elem.split("===")[0]
if len(words) > 0 and unsolved_elem == words[0]:
print(line, file=open("" str("solved") ".txt", "a",encoding='ISO-8859-1'))
CodePudding user response：
it would need to run two nested loops - and it would need to read from file book in two loops - so it would be better first to read data book.txt and create dictionary.
I use io only to simulate file in memory - so everyone can simply copy and run it.
But you should use open()
In this version I assumed that book may have the same number many times so it needs list to keep all text for this number.
book_txt = '''1:1:1 text1
1:1:2 text2
1:1:3 text3
1:1:4 text4
1:1:5 text5
1:1:6 text6
1:1:7 text7
4:2:3 other3
4:2:4 other4
4:4:5 other5'''
import io
# --- read book.txt ---
book = {}
#with open("book.txt") as f:
with io.StringIO(book_txt) as f:
for line in f:
number, text = line.strip().split(" ", 1)
if number not in book:
book[number] = []
book[number].append(text)
for item in book.items():
print(item)
Result:
('1:1:1', ['text1'])
('1:1:2', ['text2'])
('1:1:3', ['text3'])
('1:1:4', ['text4'])
('1:1:5', ['text5'])
('1:1:6', ['text6'])
('1:1:7', ['text7'])
('4:2:3', ['other3'])
('4:2:4', ['other4'])
('4:4:5', ['other5'])
And similar with file numberssearch.txt - first I would read all line and run split('===')
numberssearch_txt = '''1:1:1===4:1:2===0---0
1:1:1===4:2:3===-1----1
1:1:1===4:3:4===-2----2
1:1:1===4:4:5===-3----3
1:1:1===4:5:6===-4----4
1:1:1===4:6:7===-5----5'''
import io
# --- read numberssearch.txt ---
unsolved = set()
#with open ("numberssearch.txt") as f:
with io.StringIO(numberssearch_txt) as f:
for line in f:
parts = tuple(line.strip().split('==='))
unsolved.add(parts)
for item in unsolved:
print(item)
Result:
('1:1:1', '4:5:6', '-4----4')
('1:1:1', '4:4:5', '-3----3')
('1:1:1', '4:1:2', '0---0')
('1:1:1', '4:3:4', '-2----2')
('1:1:1', '4:6:7', '-5----5')
('1:1:1', '4:2:3', '-1----1')
And later I would search numbers from book in unsolved
for number1, number2, rest in unsolved:
if (number1 in book) and (number2 in book):
# nested loops which use `book`
for text1 in book[number1]:
for text2 in book[number2]:
print(number1, text1, number2, text2, rest)
Result:
1:1:1 text1 4:4:5 other5 -3----3
1:1:1 text1 4:2:3 other3 -1----1
Full working code:
book_txt = '''1:1:1 text1
1:1:2 text2
1:1:3 text3
1:1:4 text4
1:1:5 text5
1:1:6 text6
1:1:7 text7
4:2:3 other3
4:2:4 other4
4:4:5 other5'''
numberssearch_txt = '''1:1:1===4:1:2===0---0
1:1:1===4:2:3===-1----1
1:1:1===4:3:4===-2----2
1:1:1===4:4:5===-3----3
1:1:1===4:5:6===-4----4
1:1:1===4:6:7===-5----5'''

If book.txt may have every number only once then code can be simpler
