You can usually easily and safely do copy-pasting with IPython, through the commands %cpaste (manually ending code with --) and %paste (execute code immediately). This is very handy for testing code that you copy from web pages, for instance, or from your editor: these commands even strip leading prompts (like In[1] and ...) for you.
IPython also has a %run command that runs a program and leaves you in a Python shell with all the variables that were defined in the program, so that you can play with them.
In order to get help on these functions: %cpaste?, etc.

You can simply convert all tabs to spaces and remove ALL empty lines. So you will be able to paste any code to python console (e.g.: python2.6)

See Pyperclip. Example (taken from Pyperclip site):
import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
spam = pyperclip.paste()
Also, see Xerox. But it appears to have more dependencies.
On macOS, use subprocess.run to pipe your text to pbcopy:
import subprocess
data = "hello world"
subprocess.run("pbcopy", text=True, input=data)
It will copy "hello world" to the clipboard.
You will want to pass pyperclip.paste() the same place you would place a string for your entry or text widget inserts.
Take a look at this example code.
There is a button to copy what is in the entry field and one to paste to entry field.
import tkinter as tk
from tkinter import ttk
import pyperclip
root = tk.Tk()
some_entry = tk.Entry(root)
some_entry.pack()
def update_btn():
global some_entry
pyperclip.copy(some_entry.get())
def update_btn_2():
global some_entry
# for the insert method the 2nd argument is always the string to be
# inserted to the Entry field.
some_entry.insert(tk.END, pyperclip.paste())
btn = ttk.Button(root, text="Copy to clipboard", command = update_btn)
btn.pack()
btn2 = ttk.Button(root, text="Paste current clipboard", command = update_btn_2)
btn2.pack()
root.mainloop()
Alternatively you could just do Ctrl+V :D
If you're already using tkinter in your code, and all you need is the content in the clipboard. Then tkinter has an in-built method to do just that.
import tkinter as tk
root = tk.Tk()
spam = root.clipboard_get()
To add the copied text in a tkinter Entry/Textbox, you can use a tkinter variable:
var = tk.StringVar()
var.set(spam)
And link that variable to the Entry widget.
box = tk.Entry(root, textvariable = var)
[SOLVED]
Yo. Please use the most dumbed down language, because I've literally never done this stuff, Idk how python works. And at this moment, I'm not exactly trying to. Im just trying to copy/paate a command. I am simply trying to copy/paste code from a guide and it keeps saying I have a syntax error. I think I figured out that you dont actually type the $, but I dont even know if that's correct. Either way, I continue to get a syntax error with the arrow pointing to seemingly random letters.
Please help.
Edit: This is the simple command given to download a HTTP library for Python called "Requests":
$ python -m pip install requests
Edit2: Thanks to social_nerdtastic for answering. I just had to use cmd. I had a feeling it was something simple and fundamental that I just didn't know
If you want to copy something from the python console: Highlight what you want to copy and right click on the top border of the python console>edit>copy
If you want to paste into python console window: Make sure the coping mentioned above is the last action taken, and you will be able to simply right click I'm the python console window black area and it will automatically paste. You can also right click on the top border and follow the >edit>paste menu item.
Hope that helps.
try using magic commands %paste or %cpaste above the copied line of code. This will prevent any unexpected errors. Use % for line magic and %% for cell magic.
The main problem with your code is that you create a new PhotoImage for each pixel! Instead, create the PhotoImage once and just add the pixels in the double-for-loop.
def box(event):
yaxis(event)
canvas.create_rectangle(x1, y1, x2, y2)
picture = PhotoImage(width=(x2-x1), height=(y2-y1))
for x in range(x1, x2):
for y in range(y1, y2):
r, g, b = photo.get(x, y)
picture.put("#%02x%02x%02x" % (r, g, b), (x-x1, y-y1))
picture.write('new_image.gif', format='gif')
Also, the line tuple(map(int, value.split(" "))) in your getRGB function is wrong, as value is already the tuple you want to create, not a string.1) As you can see, I just 'inlined' that part directly into the box function. Another problem was that you wrote the copied pixels to x and y, but you have to write them to x-x1 and y-y1 instead.
Update 1: 1) It seems like the return value of PhotoImage.get depends on the version of Python/Tkinter you are using. In some versions, it returns a tuple, like (41, 68, 151), and in others, a string, like u'41 68 151'.
Update 2: As pointed out by @Oblivion, you can in fact just use the from_coords parameter of PhotoImage.write to specify the region of the picture to be saved to file. With this, the box function can be simplified as
def box(event):
yaxis(event)
canvas.create_rectangle(x1, y1, x2, y2)
photo.write('new_image.gif', format='gif', from_coords=[x1, y1, x2, y2])
import tkinter
from tkinter import *
import base64
root = Tk()
def action(canvas):
canvas.bind("<Button-1>", xaxis)
canvas.bind("<ButtonRelease-1>", yaxis)
canvas.bind("<ButtonRelease-1>", box)
def xaxis(event):
global x1, y1
x1, y1 = (event.x - 1), (event.y - 1)
print (x1, y1)
def yaxis(event):
global x2, y2
x2, y2 = (event.x + 1), (event.y + 1)
print (x2, y2)
def box(event, photo):
x1, y1 = (event.x - 1), (event.y - 1)
x2, y2 = (event.x + 1), (event.y + 1)
canvas.create_rectangle(x1, y1, x2, y2)
new_photo = copy_photo(photo, x1, y1, x2, y2)
new_photo.write('new_image.gif', format='gif')
def copy_photo(photo, x1, y1, x2, y2):
new_photo = PhotoImage(width=photo.width(), height=photo.height())
for x in range(photo.width()):
for y in range(photo.height()):
if x1 <= x < x2 and y1 <= y < y2:
r,g,b = getRGB(photo, x, y)
new_photo.put("#%02x%02x%02x" % (r,g,b), (x,y))
else:
new_photo.put(photo.get(x, y), (x,y))
return new_photo
def getRGB(photo, x, y):
value = photo.get(x, y)
return tuple(map(int, value.split(" ")))
canvas = Canvas(width=500, height=250)
canvas.pack(expand=YES, fill=BOTH)
photo = PhotoImage(file="picture.gif")
canvas.create_image(0, 0, image=photo, anchor=NW)
canvas.config(cursor='cross')
action(canvas)

I'm trying to learn Python by taking some codes for games like Snake. I want to copy and paste the code into Python, change some things up a bit in order to learn how everything works, and then begin making my own sets of code. But everytime I copy and paste more than one line of code into, Python launches Snake, and stops responding and I'm forced to cloe it. Is there anyway around this?
Here is a link to a video showing what happens: https://youtu.be/LsoJG4LHY4A
