How to make python code read a certain line of text in a .txt file?

Question

So i have been fiddling around with python and league of legends. And i found out you can make notes in game. So i thought about making python code read a line of text from the note i made in game, like "Lux no flash", but it doesn't seems to be able to read it at all, it only works when i do it manually with the exact same code. Here is my code:

import os import time def main(): os.chdir('C:\\Riot Games\\League of Legends\\RADS\\solutions\\lol_game_client_sln\\releases\\0.0.1.237') f=open("MyNotes.txt", "r") if f.mode == 'r': lines=f.readlines() text = lines[4] time.sleep(0.1) if text == 'Lux no flash': print('Done') else: print('Something went wrong') f.close() if __name__== "__main__": main()

The output is "something went wrong", but when i do it manually it says "done". I feel like python cant read league code. Maybe you guys know how to do this... This is the .txt file im trying to access:

################################################## 2018-09-13_18-57-33_ ################################################## Lux no flash

Lux with big or small L is what makes your code not work I think — Cut7er

I found that its the hashes but i'm not certain, the code doesn't care about case and if it is the hashes i need a fix xD — John Clarkson

1) with .readlines(), the line separator is preserved in the resulting strings, so you need to look for 'Lux no flash\n'; 2) lists are zero-indexed, so this line is at position 3, not 4 — Mikhail Burshteyn

@JohnClarkson I agree this should not retrieve the line if cases do not match and not using any .lower() to compare — vash_the_stampede

What do you mean "the code doesn't care about case"? == certaintly is case-sensitive. — Charles Duffy

Using lux.txt:

################################################## 2018-09-13_18-57-33_ ################################################## Lux no flash

Code:

content = [] with open('lux.txt', 'r') as f: for line in f: content.append(line.strip('\n')) for i in content: if 'Lux no flash' == i: print("Done") else: pass

Better @pygo

with open('lux.txt', 'r') as f: content = f.read() if 'Lux no flash' in content: print("Done") else: print("No else, this works :)")

Output:

(xenial)vash@localhost:~/python/stack_overflow$ python3.7 lux.py Done

I'm Just taking a file on an assumption basis:

# cat MyNotes.txt there is Lux no flash in line there is Something went wrong There is nothing lux no flash this is all test

So, just looking for the word 'Lux no flash' you are searching into your file, we can simply do as below.. but its case sensitive.

It's always best practice to use with open() method to read a file.

import os import time def main(): with open("MyNotes.txt") as f: for line in f.readlines(): if 'Lux no flash' in line: print('Done') else: print('Something went wrong') if __name__== "__main__": main()

Output result will be :

Done Something went wrong Something went wrong Something went wrong

Even tried using the lux.txt , it works as expected with my code.

import os import time def main(): with open("lux.txt") as f: for line in f.readlines(): #line = line.strip() # use can use the strip() or strip("\n") #line = line.strip("\n") # if you see white spaces in the file if 'Lux no flash' in line: print('Done') else: pass if __name__== "__main__": main()

Resulted outout is:

# test.py Done
