Errno 2 No such file or directory "I get this error even with one line of code that should work"

I'm just starting with python and I want to make a simple login system with text files. Everytime I run the code I get this error. It doesn't even make the text file. Before this, I could run my code and it made a file but now it doesn't. I tried just one line of code to open a text file but that doesn't work either.(line of code: f = open("demofile.txt")) I also tried to google it, no solution. I don't know what to do?
def AskForAccount():
status = input("Do you have an account? ")
if status == "yes":
logIn()
elif status == "no":
createAccount()
else:
print("Type yes or no, please.")
AskForAccount()
def createAccount():
name = str(input("username: "))
password = str(input("password: "))
f = open("dataBank.txt", 'r')
info = f.read()
if name in info:
return 'Name unavailable'
f.close()
f = open("dataBank.txt", 'w')
info = info + ' ' + name + ' ' + password
f.write(info)
def logIn():
username = str(input("username: "))
password = str(input("password: "))
f = open("dataBank.txt", "r")
info = f.read()
info = info.split()
if name in info:
index = info.index(username)+1
usrPassword = info[index]
if usrPassword == password:
return "welcome back," + username
else:
return 'password incorrect'
else:
return 'Name not found'
print(AskForAccount())

i dont know whats your logic but to create a file you need to use a w+
try it by de the code
def AskForAccount():
status = input("Do you have an account? ")
if status == "yes":
logIn()
elif status == "no":
createAccount()
else:
print("Type yes or no, please.")
AskForAccount()
def createAccount():
name = str(input("username: "))
password = str(input("password: "))
try:
f = open("dataBank.txt", 'r')
info = f.read()
if name in info:
return 'Name unavailable'
f.close()
except:
return 'Data base donest exists. creating one...'
f = open("dataBank.txt", 'w+')
info = info + ' ' + name + ' ' + password
f.write(info)
def logIn():
username = str(input("username: "))
password = str(input("password: "))
f = open("dataBank.txt", "r")
info = f.read()
info = info.split()
if username in info:
index = info.index(username)+1
usrPassword = info[index]
if usrPassword == password:
return "welcome back," + username
else:
return 'password incorrect'
else:
return 'Name not found'
print(AskForAccount())

The error you get in f = open('demofile.txt') is because open takes an additional argument 'mode' whose default value is 'r' for read. If the passed filename does not exist you get the described error.
Use f = open('demofile.txt','w') instead for writing to a file. This creates a new file if the filename does not exist.

How to make a separate "timer-like" function to set a variable, while the main loop keeps running?

I'm trying to write a Python script, the main function of the code is a while loop always looking for a keyword, and when the keyword is found, it'll exit the script.
import telepot
import datetime
import time
bot = telepot.Bot('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx')
print ('start listening to replies')
last_update = 0
update_offset = 0
f = open('last_update_id.txt', 'r')
if f == '':
last_update = 0
elif type(f) == str:
last_update = int(f)
elif type (f) == int:
last_update = f
f.close
update_offset = last_update + 1
#START LOOP UNTIL SATISFIED WITH REPLY
while true:
#get update
response = bot.getUpdates(offset=update_offset)
listOfSenders = []
for i in response:
#INTERPRETION OF CURRENT MESSAGE
update_id = i['update_id']
message = i['message']
whoSent = message['from']
senderUsername = whoSent['username']
timestampEpoch = message['date']
timestampHuman = datetime.datetime.fromtimestamp(timestampEpoch).strftime('%Y-%m-%d %H:%M:%S')
text = message['text']
print(text + ' from ' + sender + ' at ' + timestampHuman + ' server\'s time')
listOfSenders.append(senderUsername)
#TAKE ACTION TO MESSAGE
#is boss here?
if 'boss' in listOfSender:
bossIsPresent = 'yes'
else:
bossIsPresent = 'no'
if 'done' in text:
#job is done, bye
jobDone = 'yes'
else:
jobDone = 'no'
if bossIsPresent = 'yes':
bot.sendMessage(zzzzzzz, 'My boss is here. Goodbye')
#boss not here, reply
elif jobDone = 'yes':
bot.sendMessage(zzzzzzz, 'OK. My Job is done. Goodbye')
#write last update_id to file
f = open('last_update_id.txt', 'w+')
f.write(str(update_id))
f.close
#exit
exit
elif jobDone = 'no':
bot.sendMessage(zzzzzzzz, 'Huh?!')
#PREPARE FOR NEXT UPDATE
#the next update_offset
update_offset = update_id + 1
time.sleep(10)
#write last update_id to file
f = open('last_update_id.txt', 'w+')
f.write(str(update_id))
f.close
What I'm trying to achieve is, as long as boss has replied in the past five minutes, the bot replies nothing, after the five minutes ran out, then the bot will reply "Boss is not here". And every time boss replies, it'll reset the five minutes. But at any time it should be detecting for 'done'. How do I do this?

How to print weather information to the console in python

I'm currently creating a text based console program in python and I want to add a command to display the current weather using a zip code. I have tried googling it extensively and can't seem to find anything good. The solutions that would work for what I'm trying to do are all using technology I'm not familiar with that are used to make actual apps with python. There is currently no UI and I'm a beginner in python so the more readable and easily understandable the solution the better.

There are 2 main ways to do this.
The first one is to webscrape, using requests and beautifulsoup4. This can most easily be done from google, since if you search "weather {city-name}" it gives you a summary of the weather there.
The second is to use an api such as openweathermap, for which there is a great geeksforgeeks tutorial on:

IRC Twitch somehow start ignoring messages

I'm just trying to make a 'Twitch Plays' game. I used a tutorial for making Twitch Plays games. I need to re-run this code every five minutes as it ignores the messages. I'm making Threes game on Scratch. I checked for all the possible bugs and it works very well. This game is based on moving tiles that contain numbers on them. Any suggestions regarding the IRC twitch ignoring all messages will be highly appreciated.
The code is shown here below.

Returning to 'main menu' for mini email program

So for practice, I tried writing a simple program to read/write emails from the terminal/python shell. My problem is that whenever I try entering an invalid response, it ends the program rather than returning to the 'main menu,' so to speak. Same problem for when I try to give the option of quitting the program and asking the user to confirm that they want to exit. This is my code:
import smtplib
import imaplib
import email
print 'Welcome to NhuMail'
print '\n \nPlease enter your login information: \n'
user = raw_input('Email User:')
pw = raw_input("Password:")
def check_mail(user, pw):
# Login to INBOX
imap = imaplib.IMAP4_SSL("imap.gmail.com", 993)
imap.login(user, pw)
imap.select('INBOX')
# Use search(), not status()
status, response = imap.search('INBOX', '(UNSEEN)')
unread_msg_nums = response[0].split()
# Print the count of all unread messages
print '\n\nYou have %s unread messages.' % (len(unread_msg_nums))
def read_mail():
imap = imaplib.IMAP4_SSL("imap.gmail.com", 993)
imap.login(user, pw)
imap.list()
imap.select("inbox")
status, response = imap.search('INBOX', '(UNSEEN)')
unread_msg_nums = response[0].split()
result, data = imap.uid('search', None, "ALL") # search and return uids instead
latest_email_uid = data[0].split()[-1]
result, data = imap.uid('fetch', latest_email_uid, '(RFC822)')
raw_email = data[0][1]
email_message = email.message_from_string(raw_email)
print email_message['To']
print email.utils.parseaddr(email_message['From']) # for parsing "Yuji Tomita" <yuji#grovemade.com>
email_items = email_message.items()
# print all headers
print email_items[1]
print email_items[2]
print email_items[5]
print '\n'
b = email.message_from_string(raw_email)
if b.is_multipart():
for payload in b.get_payload():
# if payload.is_multipart(): ...
print payload.get_payload()
else:
print b.get_payload()
def new_mail():
from_add = user
to_add = raw_input('Enter TO address:')
msg = raw_input('Enter desired message:')
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(user,pw)
server.sendmail(from_add,to_add,msg)
def exit_mail():
confirm_exit = raw_input('Are you sure you want to exit? (Yes/No):')
server = smtplib.SMTP('smtp.gmail.com:587')
if confirm_exit == 'Yes':
server.quit()
print 'Nice Nhu-ing you! Come again soon :)'
elif confirm_exit == 'No':
return prompt
def mail_options():
prompt = raw_input('Say \'Nhu\' to compose a message \nOR \nSay \'Read\' to read unread message \nOR \nSay \'Escape\' to exit NhuMail: \n')
while True:
if prompt == 'Nhu':
new_mail()
return prompt
elif prompt == 'Read':
read_mail()
return prompt
elif prompt == 'Escape':
exit_mail()
break
else:
print 'You didn\'t enter one of the options!'
return prompt
check_mail(user,pw)
mail_options()

It looks like you want to keep calling mail_options(). You can do this with an infinite loop:
while True:
mail_options()
You could also put the loop inside mail_options():
def mail_options():
while True:
prompt = raw_input('Say \'Nhu\' to compose a message \nOR \nSay \'Read\' to read unread message \nOR \nSay \'Escape\' to exit NhuMail: \n')
while True:
if prompt == 'Nhu':
new_mail()
elif prompt == 'Read':
read_mail()
elif prompt == 'Escape':
exit_mail()
break
else:
print 'You didn\'t enter one of the options!'

Try changing your mail_options() to this:
def mail_options():
while True:
prompt = raw_input('Say \'Nhu\' to compose a message \nOR \nSay \'Read\' to read unread message \nOR \nSay \'Escape\' to exit NhuMail: \n')
if prompt == 'Nhu':
new_mail()
elif prompt == 'Read':
read_mail()
elif prompt == 'Escape':
exit_mail()
break
else:
print 'You didn\'t enter one of the options!'
You present the prompt once and then as soon as you get their result, you return what they said after running the specified function, and then because you use a return keyword, it breaks out of the loop and function and exits the program.

The issue in your program lies in mail_options(). You have an infinite loop, that can only run a single time, and then exits every time time due to the use of a return statement. Make an infinite loop to continuously show mail_options(), and it should fix your issue. You're only calling it once, which is why it exits.
You can do:
while True:
mail_options()
Another option would be asking the prompt inside the loop, and ridding the function of return statements.
def mail_options():
while True:
prompt = raw_input('Say \'Nhu\' to compose a message \nOR \nSay \'Read\' to read unread message \nOR \nSay \'Escape\' to exit NhuMail: \n')
if prompt == 'Nhu':
new_mail()
elif prompt == 'Read':
read_mail()
elif prompt == 'Escape':
exit_mail()
return # Get out of the function.
else:
print 'You didn\'t enter one of the options!'
