Missing Postional Arguments

[Psypher1]

I am making an accommodation program and I ran into this error.I saw other threads with the same issue om the site but they didn't help me figure it out. I am running into the error after I search the realtor file for a match. That is the login part of the program, when a student logs in.

This is my main file:

from classes.users import Student, Realtor import csv # declaration of files students_file = "students.txt" realtor_file = "realtor.txt" def main(): prompt() option_select() def prompt(): print("Welcome to Mason Real Estate") print("Please Login or Create Account") # selection to crete account or login def option_select(): print("1. Create Account \n2. Login\n") user_choice = int(input("What would you like to to today?: ")) if user_choice == 1: create_user() elif user_choice == 2: login_user() # choice to create student or realtor account def create_user(): print("Are you a student or realtor?") print("1. Student \n2. Realtor\n") role = int(input("You are: ")) if role == 1: is_student() elif role == 2: is_realtor() # choice to lgin student or realtor def login_user(): print("Student or Realtor?") print("1. Student \n2. Realtor\n") login_type = int(input("You are: ")) if login_type == 1: student_login() elif login_type == 2: realtor_login() # when create account is student def is_student(): print("\nPlease complete the following: ") user = Student(input("Username: ").capitalize(), input("Phone: ").capitalize()) # call method from student class user.create_account(user.username, user.phone) # when crete acount is realtor def is_realtor(): print("\nPlease complete information about yourself and you r rental: ") user = Realtor(input("Username: "), input("Phone number: "), input("City: "), input("Suburb: "), input("Rooms: ")) # call method from realtor class user.create_account(user.username, user.phone_number, user.city, user.suburb, user.rooms) def student_login(): found = False print("\nPlease login") while not found: # imput of details to login name = input("Enter your name: ").capitalize() phone = input("Number: ").capitalize() # open student file with open(students_file, 'r') as all_students: student_data = csv.reader(all_students) for student in student_data: # check if input has matches in file if (name and phone) in student: print("\nWelcome " + name.capitalize()) search_apartment() found = True break else: print("User not found. Try again") break all_students.close() def realtor_login(): pass def search_apartment(): print("What kind of a place would you like?: ") find = Realtor(input("What city?: ").capitalize(), input("What suburb?: ").capitalize(), input("How manny room?: ").capitalize()) find.apartment_info(find.city, find.suburb, find.rooms) main()

This is where my classes are:

import csv WRITE = 'w' APPEND = 'a' READWRITE = 'w+' # class for students class Student: def __init__(self, username, phone): self.username = username self.phone = phone # method to create student account def create_account(self, username, phone): self.username = username self.phone = phone # create syudent file and append it students_file = "students.txt" file = open(students_file, mode=APPEND) file.write(username + "," + phone + "\n") file.close() print("\nThank You. Your Account has been created successfully") # realtor class class Realtor: def __init__(self, username, phone_number, city, suburb, rooms): self.username = username self.phone_number = phone_number self.city = city self.suburb = suburb self.rooms = rooms # method to create realtor account def create_account(self, username, phone_number, city, suburb, rooms): self.username = username self.phone_number = phone_number self.city = city self.suburb = suburb self.rooms = rooms # create realtor file and append to it realtor_file = "realtor.txt" file = open(realtor_file, mode=APPEND) file.write(username + "," + phone_number + "," + city + "," + suburb + "," + rooms + "\n") print("\nThank You. Your Account has been created successfully") def apartment_info(self, city, suburb, rooms): self.city = city self.suburb = suburb self.rooms = rooms realtor_file = "realtor.txt" # open realtor file with open(realtor_file, 'r') as all_realtors: realtor_data = csv.read(all_realtors) # check if searched parameter exist in the file for realtor in realtor_data: if (city and suburb and rooms) in realtor: print("Found") all_realtors.close() def apart_info(self): return '{} {} {}'.format(self.city, self.suburb, self.rooms)

And the error:

Traceback (most recent call last): File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 112, in <module> main() File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 11, in main option_select() File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 28, in option_select login_user() File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 48, in login_user student_login() File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 90, in student_login search_apartment() File "C:/Users/Jacques/PycharmProjects/Mason_Housing/main.py", line 107, in search_apartment input("How manny room?: ").capitalize()) TypeError: __init__() missing 2 required positional arguments: 'suburb' and 'rooms'

I have been trying to locate where I left an argument but I don't see where it is. Would you please show me what I am supposed to do

Thank you

Look on line 29 of your classes file. You define five arguments to the __init__ for the Realtor class: username, phone_number, city, suburb, and rooms. Then on line 107 in main.py, you only have three input statements to generate those arguments. It appears you are not supplying username or phone_number, so you need to supply those from somewhere.

Using inputs when calling the class is kind of odd. I would gather the inputs separately, and then create the instance:

city = input("What city?: ").capitalize() suburb = input("What suburb?: ").capitalize() rooms = input("How manny rooms?: ").capitalize() find = Realtor(username, phone_number, city, suburb, rooms)

[Psypher1]

Oh I see, thank you. So it should be like this, yes?:

 print("What kind of a place would you like?: ") username = "" phone_number = "" city = input("What city?: ").capitalize() suburb = input("What suburb?: ").capitalize() rooms = input("How manny rooms?: ").capitalize() find = Realtor(username, phone_number, city, suburb, rooms) find.apartment_info(city, suburb, rooms)

Another question. If a realtor logged in, what would be the best way to return the data in their row? for example the row with Markus

James,0774755572,Harare,Avenues,2 Markus,0773012521,Bulawayo,Nkayi,1 Viktor,0772542779,Mutare,Wallcourt,3

Looking at the rest of your program, it's completely disjoint. Every function is completely independent of every other function, without passing any parameters or returning any values. When you log the user in you create an object instance for them. That instance should be maintained in the program, and passed to the different functions for use in doing searches or displaying information about the account. There is a basic function tutorial, linked in my signature below, that can show you use parameters and return values.

[Psypher1]

Thank you I will read through the tutorial and modify them.

Could that also be why if I try to login the second or third user it says they don't exist even though they are in the file?

[ichabod801]

No, that's a problem with your for loop that searches the file:

 for student in student_data: # check if input has matches in file if (name and phone) in student: print("\nWelcome " + name.capitalize()) search_apartment() found = True break else: print("User not found. Try again") break

First of all, the if statement is wrong. That's not how and words. You would need something more like if name in student and password and student:. That's a proper use of and, but it's not really a good way to check for a login. You seem to be storing the data with comma separated values. You need to separate out those values (like with split(',')), and check the correct values in the data against those input by the user.

Say you get that working. You check the first data item against what was input. Let's assume it doesn't match. So it goes to the else statement, which says the user was not found, and breaks out of the search loop. So you loop will only ever match the first user in the data. It will never login anyone else.

The fix involves unindenting the else statement (and removing the break):

 for student in student_data: # check if input has matches in file if (name and phone) in student: print("\nWelcome " + name.capitalize()) search_apartment() found = True break else: print("User not found. Try again")

Now the else is on the for, not on the if. The else on a for loop is triggered if the loop ends normally, without a break statement. Since you break when you find someone, the else will trigger if you don't find anyone.

[Psypher1]

Oh alright, thank you. Daeling with the functions now

Also, Instead of

if (name and phone) in student:

It would be better to use a nested if perhaps?

[ichabod801]

No, it would be better to break out name and phone from student, and test those directly. You appear to be using comma separated values, so fields = student.split(',') will give you a list of the different items that are stored for that student. One of those is the name of the student, and one is their name. Test those. So maybe if name == fields[0] and phone == fields[1]: if I am reading your data example correctly.
