Python Tkinter线程问题：system（）最多接受1个参数（给定27个）

我有这个代码来安装Pygame

import os
import tkinter as tk
import threading

root = tk.Tk()

canvas1 = tk.Canvas(root, width=300, height=300, bg='gray90', relief='raised')
canvas1.pack()


def run_command(command):
    # for i in range (5):
    threading.Thread(target=os.system, args=f'cmd /c "{command}"').start()  # TypeError: system() takes at most 1
    # argument (27 given)


button1 = tk.Button(text='      Run Command      ', command=lambda: run_command("pip install pygame"), bg='green', fg='white',
                    font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 150, window=button1)

root.mainloop()

但它抛出了一个错误；TypeError:system（）最多接受1个参数（给定27个） 我可以做

os.system（f'cmd/c“{command}”）

，但是按钮冻结了，所以我不想这样。我如何修正我的错误

import tkinter as tk
import threading

root = tk.Tk()

canvas1 = tk.Canvas(root, width=300, height=300, bg='gray90', relief='raised')
canvas1.pack()


def run_command(command):
    # for i in range (5):
    threading.Thread(target=lambda: os.system(command)).start()


button1 = tk.Button(text='      Run Command      ', command=lambda: run_command("pip install pygame"), bg='green', fg='white',
                    font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 150, window=button1)

root.mainloop()

试试看

请尝试此操作并查看。

发生错误的原因是线程中的“args”参数。线程需要一个元组

将行更改为

threading.Thread（target=os.system，args=（f'cmd/c“{command}”）.start（）

解决了这个问题

完整代码：

import os
import tkinter as tk
import threading

root = tk.Tk()

canvas1 = tk.Canvas(root, width=300, height=300, bg='gray90', relief='raised')
canvas1.pack()


def run_command(command):
    # for i in range (5):
    print(os.system)
    threading.Thread(target=os.system, args=(f'cmd /c "{command}"', )).start()  # TypeError: system() takes at most 1
    # argument (27 given)


button1 = tk.Button(text='      Run Command      ', command=lambda: run_command("pip install pygame"), bg='green', fg='white',
                    font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 150, window=button1)
