Python 3 Lesson 14: Save & Load Data

Writing to a .py file and loading back in the values.

[@gamergotdis2348]

Tysm this is all I needed for my programming project in school! I was trying to store user information but I failed multiple times, this really helped 10/10 thank you again.

[@CLyon-cc9jp]

I never would have thought of using a python extension over a text extension to save my program data. Perfect! Saves so much time not having to parse every entry. Nice.

[@Nezuzo]

Thank you so much man, so simple and easy to understand.

[@faisaltaher851]

thx you so much you helped me with a problem the was happening for 2 day FREAKING 2 DAY thx you, you solved my problem :)

[@robertovargas5839]

This is super tedious if implemented even on a small text based game but its good to see there is a way of getting it done.

[@BiggestNaviaFan]

thanks a lot this helps with my text based boss fighter

[@dofnithedope3758]

THANK YOU!!! I have been trying to figure out how to do this and literally every other tutorial was just too complicated for my small brain.

[@ashmeepragnaroy8976]

Thanks a lot!! This was a way of saving user data permanently! Thanks again!

[@blackblocky3866]

very good tutorial, thanks!

[@richitomiau.]

tysm u make it so easy to understand and save my time

[@zeperoxx]

Thx, it helped a lot, especially I didn't have any success before. Every video or post I find only shows how to write a sentence, not full variable

[@EJStudios17]

If you have separate def’s it gives a name error. Is their a fix for this?

[@ktz2625]

How can I save and load a string (name = "KTZ") because I can't put the "" in the f.write function. Please help.

[@TaFr-mg5dy]

Thank you for your useful tutorial

Rafy-Ivan Morales 0 seconds ago I'm a new student trying to learn, so I can become a programmer with python and I have a project on how to make a port scan. So far I already make a port scan with Python3, and it scans fine, give a date and everything working good so far. I see on your video tutorial you give example on how to send and receiving data. I would like to ask for your advice if you can and guide me on how I will add this 3 in a Python script, I have: 2. System should look for all the ports between the range of 1 to 1025 3. If the Ports is open, it should create a file and add an entry for port number 4. In case of any exception for instance “host is not available”, “host name could not be resolved” or due to any other error, you need to write that exception into the same file. Thank you and Merry Christmas.

Thank you!

How could I delete what was on the second file? Like in this example, if I wanted to delete the health from the Savytime.py file?

[@psychic_digit]

I think you just have to overwrite it to 0 or something.

[@quirkychamp9152]

thank you so much i look a lot for that

[@corn3237]

I can’t thank you enough. Thanks you so much. You have saved me literally hours more of stress. I’ve tried to make multiple save files but it always gave me a error, is there a way?

[@DanielMurrayMakes]

What's the error say?

[@ifaisalne9781]

Man you are really pro, i have a Q Can you tell me how to save a word like True False value in py file ?

[@orangeleaf36]

What about for saving a string?

[@sandpaperunderthetable6708]

How do you check if a file exists? Do you use a try and catch and open a file for read? Does that work?

[@DanielMurrayMakes]

Yes a Try would work there, good idea!

[@sandpaperunderthetable6708]

@@DanielMurrayMakes thanks

[@sandpaperunderthetable6708]

@@DanielMurrayMakes will opening a non existant file to read cause an error?

[@DanielMurrayMakes]

@@sandpaperunderthetable6708 Yeah but of you use Try with an Except then it will just jump over to the except. Bad coding probably but it'll work!

[@dorgan8777]

Thanks I'm currently working on a text based os called red warp

[@hayderalanbari6740]

How is it going?

[@matthewwhite3744]

Yeah how's it going?

[@ProFNaFPlayer._1987]

It just doesnt work. The file isn't showing up , and when I created the file by myself , It's empty

[@Greg2]

How do I make it so everytime I run the command, it sends how many times I have ran the file?

[@ProFNaFPlayer._1987]

I know the answer , still wanna know?

[@theprogrammer1903]

[@unrealnovice7330]

UnboundLocalError: local variable 'loseCount' referenced before assignment ??? its pretty usless if i cant change bevor im loading

[@unrealnovice7330]

[@unrealnovice7330]

def Save(): f = open("SaveFile.py",mode="w") wins = f.write("winCount = " + str(winCount) + " ") loses = f.write("loseCount = " + str(loseCount) + " ") f.close()

[@quirkychamp9152]

[@DanielMurrayMakes]

Copy-paste the exact error here, maybe I can help

[@quirkychamp9152]

Ow I fixed it already thx you so much

[@quirkychamp9152]

I'm new to this so ya

[@quirkychamp9152]

Big fan

[@KlaroNebulous]

for me it only saves the data in the first line idk why

[@adamhall7077]

Did you put the " " in? You might have put a "/n" instead.

[@ThatGuyexe]

loll so cool

[@ringingstrings6078]

How do I Put my "Saveytime" in another folder and open it

[@survivalist2607]

instead of "from Saveytime import *" put "from yourfoldernamehere import *" or "from yourfoldernamehere import Saveytime" but you'll have to put a "Saveytime." before any variables that are getting pulled from the File, to shorten it put "from yourfoldernamehere import Saveytime as namehere" that way, you'll have to put "namehere." before every variable getting pulled from there. Ofcourse you can put something else other than namehere, it was used as an example.

[@rakawiratama]

can we customize the location of the saved file? In my case it is always saved in C/Users/(My username)/... and I want to save it somewhere else

[@mr.broken5539]

[@spookyleo2589]
