Newbie here, wondering what's up with this code..

I've been tinkering with Python as my first computer programming language (unless you count Batch and Bash as fully-fledged languages). I think I've done pretty well overall, keeping it neat and easy to read, but the highlighted piece is what I'm having trouble with. I found the code around the web (googled "python append text") and tried to wrestle with it.

Thanks in advance!

Code:

#Python Application
#login_user.py

#Pathname Finder
import sys, os
pathname = os.path.abspath(pathname)

class start_app:
        def open_menu(self):
                print "Welcome to the [redacted]!\n"
                print "---------------\n"
                print "Please log in!\n"
                
                time.sleep(5)

                username = raw_input("> ")
                
                f = open(user_info.txt", "r")
                searchlines = f.readlines()
                f.close()
                for i, line in enumerate(searchlines):
                        if username in line: print line
                        else f = open("user_info.txt", "a") as myfile:
                                myfile.write(username)
                        searchfile.close()
               

start_object = start_app()

start_object.open_menu(self)

print "Thanks for looking at my script!"

Code:

                f = open(user_info.txt", "r")

Here you have a missing quote: "user_info.txt" lacks the opening one.

Code:

                        else f = open("user_info.txt", "a") as myfile:

This is totally wrong. “else” should always have a trailing colon. Also, there shouldn’t be anything following it. However, “f = open(...) as myfile:” is not correct in itself. Maybe “else” should be “with”?

Thanks for the feedback! Again, I have very little experience; everything highlighted is code I had just googled to help fit in.

I'm not sure where I can find a definitive guide on commands etc., though I would really love to learn more.

Thank you!
