Withopen module and mainsheet cycles

#Hi there ! friend n! I need help.Persians attack from the south. We need more triremis!
#the case is I can not realize. How to relate my module with main shee. There we input some
#data and immediately can get back data writting num 1.

Read up on classes and the mcv approach. That would simplify thing greatly for you.

 

[menator01]

Here is an example of using the mcv approach. I will leave the reading and writing to you but, I did setup an example menu.

class Model:
    '''
    Model does all the reading and writing to ur file
    '''
    def __init__(self):
        pass

    def write(self, file):
        with open(file, 'w') as doc:
            doc.write(input('data: '))

    def read(self, file):
        with open(file, 'r') as doc:
            data = doc.read()
            return data

class View:
    '''
        View will display out file content and other options/messages
    '''
    def __init__(self, file=None):
        self.file = file


    def show(self, arg):
        print(f'\n{arg}\n')


class Controller:
    '''
        Controller does the communications between our view and model
    '''
    def __init__(self, model, view):
        self.model = model
        self.view = view

        self.menu = {
            'Add Data': 1,
            'Read Data': 2,
            'Exit': 3
        }


if __name__ == '__main__':
    controller = Controller(Model(), View())

    while True:
        for item, option in controller.menu.items():
            print(f'{item} : {option}')
        try:
            op = int(input('>> '))
            if op in controller.menu.values():
                if op == 3:
                    controller.view.show('Goodbye!')
                    break
                else:
                    controller.view.show(f'You chose option {op}')
            else:
                controller.view.show(f'\nThat is not a valid option.\n')
        except ValueError:
            print('\nError!, That is not a valid entery.\n')

Here is an example that writes and reads a text file.

# Do the imports
from pathlib import Path

# Set file path
path = Path('test.txt')

class Model:
    '''
    Model does all the reading and writing to ur file
    '''

    # Give prompt and writes data entered to text file
    def write(self):
        with open(path, 'a') as doc:
            doc.write(input('data: ')+'\n')

    # Opens text file and grabs contents for return
    # If a file does not exist returns message
    def read(self):
        if path.is_file():
            with open(path, 'r') as doc:
                    data = doc.read()
                    return data
        return 'You need to add data for a file to be created for reading.\n'

class View:
    '''
        View will display out file content and other options/messages
    '''

    def show(self, arg):
        # Displays data
        print(f'\n{arg}')


class Controller:
    '''
        Controller does the communications between our view and model
    '''
    def __init__(self, model, view):
        # Set class variables
        self.model = model
        self.view = view

        # Create a menu. Using a dict to have some text to display and an int to perform select action
        self.menu = {
            'Add Data': 1,
            'Read Data': 2,
            'Exit': 3
        }


if __name__ == '__main__':
    # Initiate classes
    controller = Controller(Model(), View())

    # While loop so code doesn't just exicute the quit
    while True:
        # Loop through and display menu
        for item, option in controller.menu.items():
            print(f'{item} : {option}')

        # Try block to test entry and to keep code from continueos scrolling text
        try:
            op = int(input('>> '))

            # Test if entered option is valid. If it's not within the menu option throw error.
            if op in controller.menu.values():
                if op == 3:
                    # if option 3 is selected exit program
                    controller.view.show('Goodbye!')
                    break
                else:
                    # Else either option 1 write entered text or option 2 display text file contents
                    if op == 1:
                        controller.model.write()
                    if op == 2:
                        controller.view.show(controller.model.read())
            else:
                controller.view.show(f'\nThat is not a valid option.\n')
        except ValueError:
            print('\nError!, That is not a valid entery.\n')

#Thank you a lot. Your work is just something else! although, too difficult for my at the moment. Here is an easy option_ for start.

information is an argument passed to the function

Maybe this will help

# Information is just an argument passed to the function.
# If you don't pass an argument it will error
def save(information):
    print(information)

# If you run this without an argument, it will error
# save()

# You can set a default argument to pass
def save2(information='Some default argument'):
    print(information)

# This will print the default argument
save2()

# Pass an argument to the function
# It will print the string passed as an argument
save('This is a passed argument')

This is about as simple as I know

# Import Path from pathlib. This will give a file path and allow us to test
# if the file exist
from pathlib import Path

# Create the file path. This will be the current project directory
file = Path('file.txt')

# Define the function for saving input data
# Opens the file and ask for input then writes
# w will overwrite the current file. Use a to append data
def save():
    with open(file, 'w') as f:
        f.write(input('data: '))

# Define a function for loading and reading the file
# We use file.is_file() for testing if the file exist.
# If the file does not exist give an error message
def load():
    if file.is_file():
        with open(file, 'r') as f:
            print(f.read())
    else:
        print('File does not exist')


# Start the while loop
while True:

    # Print out the menu
    print('1 Save, 2 Show, 3 Exit')

    # Prompt
    p = input('>> ')

    # If 1 is entered, call the save function
    # If 2 is entered, call the load function
    # If 3 is entered, exit the program
    # Else print an error, because no proper input was entered
    if p == '1':
        save()
    elif p == '2':
        load()
    elif p == '3':
        print('Goodbye!')
        break;

    else:
        print('Error!')

# Start the while loop

    # Prompt

    # If 1 is entered, call the save function

#I see. I realize partly how the mechanism works. At the moment I try to check data by login in, I saved username, I saved password, by cheking I call them from the file_ if arg in f.read(): if passw in f.read(): , but something wrong, I guess it because we need to appoint where in the file is precisely password and login. when I write if arg in f.read() or passw in f.read(): it works, but it doesnt right so. If I write if arg in f.read() and passw in f.read(): it does not work if as username or password were not in the file, although they are there.

If you are going to do a login system would be better to use a database

If you are going to do a login system would be better to use a database

hi there! what's up ? time fleeting, but the big time is not going to come true. Feel like a cat on a tin roof. Out here is hard nut to crack for me and easy breeze for you. Provided you do not mind. The heart of the matter, I write a dictionary there is an option to transfer words from English to Russian and the opposite. The business is there ought to be the notification as long as I write word which is no out there in the dictionary" there is no such word in the dictionary"

out here is a part of the code, I know how it has to look like kind of
for i in e:
if i not in list:
print('')

smth do wrong after all

def word_transfer(e:list,l:list): 
    n=input('Which language_? English>:1 Russian>:2')
    if int(n)==1: 
        e=list(map(str,e)) 
        pos=0 
        english=input('English:')
        ind=e.index(english,pos) 
        english=print(l[ind]) 
        pos=ind+1
