粘贴到Python中时如何截断回车

Question

I created a function that will copy to the system clipboard. However, when I paste the value from the clipboard, it automatically does a carriage return. This drastically affects calculations in my program.

Note: Cannot Use Pyperclip or any other installation. I can only use what's included in Python IDLE 3.8 for this

I've tried using the strip() method with the clipboard_answer variable. It still returns to the next line

def copy(solution_answer): 
    clipboard_answer = str(solution_answer)
    command = 'echo ' + clipboard_answer.strip() + '| clip' # Creates command variable, then passes it to the os.system function as an argument. CMD opens and applys echo (number calculated) | clip and runs the clipboard function
    os.system(command)
    print("\n\n\n\n",solution_answer, "has been copied to your clipboard") # Used only for confirmation to ensure copy function runs

Pretend the "|" icon is the cursor

I have a solution that was copied to my clipboard, ie 25

When I CTRL+V in the program I expect it to do this

But in actuality, the cursor is like this

25

Answer 1

Don't use os.system . Use subprocess , and you can feed the string directly to the standard input of clip without invoking a shell pipeline.

from subprocess import Popen, PIPE

Popen(["clip"], stdin=PIPE).communicate(bytes(solution_answer))

Answer 2

import pyperclip

pyperclip.copy(solution)

This should do the trick.

EDIT: The tkinter solution again since pyperclip is no option for OP.

from tkinter import Tk

r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append("hello world")
r.update()
