Code: [Select]
Arturia_Picture = Image.open("Artoria_Face_Shots_1.jpg", 'r') for line in Arturia_Picture: Arturia_Picture.write(line)

First thing that jumps out to me is that you're trying to write to a file you've just opened for reading. Searching for "python image.open" led me to this article, regarding the PIL module.

Would this work?
Code: [Select]
Arturia_Picture = Image.open("Artoria_Face_Shots_1.jpg", 'r') Arturia_Picture.show()

I'm going to try this in my code right now and let you know. Thank you!

EDIT: Okay so I uses some of the code as shown in the example that Bumber showed. But in addition I comented out that for loop as well as added the entire path.

I saw that as I added the entire path that Python gave me suggestions for what picture in my 'saved pictures' folder that I had. Picked the one I want and attempted to show it.

[Code/]

Arturia_Picture = Image.open("C:\Users\myName\Pictures\Saved Pictures\Artoria_Face_Shots_1.jpg", 'r')

Arturia_Picture.show()

[Code\]

After running this code I get a truncation error. I'm going to do some research on what that is. A simple google search gave me this: "In numerical analysis and scientific computing, truncation error is the error caused by approximating a mathematical process. Let's take three examples so that the myths surrounding the definition of truncation error can be laid to rest."

Thank you Bumber for your help. I think I made progress on my little project here.

Hi everyone. I'm trying to make an image pop up in Python after running some things in the console. I'm still a newbie.

I have tried googling to find the right module / library for this but it all seems kinda archaic. The modules available seem there for machine learning and image analysis. Where as all I want to do is simply open up an image.

I kept looking and now I find myself here: https://www.pythonforbeginners.com/files/reading-and-writing-files-in-python

Essentially, I can potentially use open() to open a file. But when I tried to copy and paste the name inside of the parenthesis I was given an error.

Code: [Select]

Arturia_Picture = Image.open("Artoria_Face_Shots_1.jpg", 'r')
    for line in Arturia_Picture:
        Arturia_Picture.write(line)

Apologies for the weak question. It seems you guys are dealing with higher level threats...And I can't afford to give out sandwiches for help atm due to covid.

You seem to be missing the \ characters from the path.

The most likely reason is that \ is the escape code, for example when you write "\n" for a new line. A \ by itself always signifies that the next character is a special character code. \t for tab and \b for backspace are other examples.

A literal \ needs to be written as \\, so that it knows that it's representing the \ character itself and not being used as an escape code.
This is a standard thing, for example batch files use % for special codes, so %% means to write an actual %.

You can also write / instead of \ to specify paths (depends on the language), but it's good to be aware of the issue with using \.

This is also used to embed " characters inside a string delineated with " characters. You can use \" to add actual " characters inside the string.

like so?

Code: [Select]

img = ImageTk.PhotoImage(Image.open("C:\\Users\Javier\\Documents\\Valkyrie"))
Here is the iteration i'm on currently.

Code: [Select]

import tkinter
from PIL import ImageTk,Image

mainWindow = tkinter.Tk()

label = (mainWindow, "Valkur")

img = ImageTk.PhotoImage(Image.open("C:\\Users\\Javier\\Documents\\Valkyrie.JPG"))

mainWindow.create_image(20, 20, anchor=NW, image=img)

mainWindow.mainloop()

I asked the same qeustion on a programmers discord and I got this link from someone. https://www.c-sharpcorner.com/blogs/basics-for-displaying-image-in-tkinter-python

The link has a small article that has this bit:

I think i'm following the rules but ehhh. I'm so lost

Simple task I set out for myself to help get better at coding was to display an image. I'm failing horribly again after picking this project up again. Can someone help?

[spoiler]
import tkinter
from PIL import ImageTk,Image

mainWindow = tkinter.Tk()

label = (mainWindow, "Valkur")

img = ImageTk.PhotoImage(Image.open("Valkyrie.jpg"))

mainWindow.create_image(20, 20, anchor=NW, image=img)

mainWindow.mainloop()

Errors:

Can someone explain to me this error a bit? If I understand the docs, the problem summary is the last bit right? Where it says that "FileNotFoundError" happened. I'm a little at a loss for words and while I did take some programming courses in college but if possible please explain as best as possible. I really don't want to be treated as anything but a noob in order to understand this.

I made thing work in Java. I went for a training exercise where the program prints out an object with things inside which in my case is a space marine chapter. I can make 1000 space marines with the name of recruit, the awesome weapon known as a bolter, and have health of '10'.

Code: [Select]

public class InputMechanisms {

	public static void main(String[] args) {
		
		//BlankMarines SpaceMarines = new BlankMarines();
		
		BlankMarines SpaceMarineChapter[] = new BlankMarines[1000];
		
		for (int x = 0; x < 1000; x++){
			BlankMarines SpaceMarine = new BlankMarines();
			
			SpaceMarineChapter[x] = new BlankMarines();
		}
		
		System.out.println("We have a space Marine:" + SpaceMarineChapter[3]);
		System.out.println("We have a space Marine:" + SpaceMarineChapter[800]);//returns null
		System.out.println("We have a space Marine:" + SpaceMarineChapter[47]); //returns null
	//	System.out.println("We have a space Marine:" + SpaceMarineChapter[1000]); //InputMechanims? 
		
		for (int y = 0; y < 1000; y++){
			System.out.println("We have a space Marine:" + SpaceMarineChapter[y]);
		}
	}
