python - 如何将 tqdm 进度条与进程同步

Question

我想创建一个 tqdm 进度条来显示某事的进度。假设我想生成一个 8192 位的 RSA 密钥。我想要一个可以显示是否完成的进度条。我怎么做？例如：

from Crypto.PublicKey import RSA
from tkinter import Tk, messagebox, simpledialog
import sys
from tqdm import tqdm
import halo
import multiprocessing as mp

root = Tk()
root.withdraw()

execute_shell_or_command = sys.executable
public_key_file = simpledialog.askstring('Key Generator',
                                         'Enter the file you want to store the public key in (requires file extension)')
private_key_file = simpledialog.askstring('Key Generator',
                                          'Enter the file you want to store the private key in (requires file '
                                          'extension)')
key_num = simpledialog.askstring('Key Generator', 'Enter the key size, in bytes')

try:
    if 'pythonw.exe' in execute_shell_or_command:
        print('Generating key....')
        key = RSA.generate(int(key_num))
    else:
        #  p = mp.Process(target=tqdm())
        spinner = halo.Halo(text='Generating key....', spinner='dots')
        spinner.start()
        # insert tqdm progressbar here
        key = RSA.generate(int(key_num))
        spinner.stop()
except ValueError:
    print('Bruu, you actually thought that a letter is a number? Shame on you!')
else:
    print('Opening (maybe creating) your files....')
    file_priv = open(private_key_file, 'wb')
    file_pub = open(public_key_file, 'wb')
    print('Exporting and writing the private key....')
    private_key = key.export_key()
    file_priv.write(private_key)
    file_priv.close()
    print('Exporting and writing the public key....')
    pub_key = key.publickey().export_key()
    file_pub.write(pub_key)
    file_pub.close()
    print(f"Hooray! The private and public key has successfully been saved to "
          f"{private_key_file} and {public_key_file}!")
