tkinter-多线程或多处理以进行循环

Question

我想优化我的程序。简而言之，它用于解压缩巨大的tar.gz存档（5 GB+）或根据输入从中提取一些文件（约20K）。

我现在面临的主要问题是窗口没有响应，但我确实需要它才能正常工作。我已经阅读了有关多处理和多线程的信息，但不确定如何将其应用于我的代码上。

你能帮我吗？

这是我解开拉链的2个功能

def unzip_tar_gz(self, ARES_tar_gz):
        row             = 22 #used for GUI
        self.debug_output("Unzip", row, "Start: ")
        tarfile_ARES    = tarfile.open(ARES_tar_gz)
        
        #counters for progress bar
        self.counter    = 0
        self.maxcount   = 1200000
        
        #extract
        for member in tarfile_ARES.getmembers():
            self.update_idletasks()
            member.name = os.path.basename(member.name)
            result      = re.search("(.*).xml", member.name)
            res         = result.group(1)
            r           = res[:-1]
            num         = int(r)
            tarfile_ARES.extract(member, self.get_folder(num))
            self.counter+=1
            
            #debug
            if self.counter%100000 == 0:
                row += 1
                self.debug_output("extract 100k", row, "Success")

        #after extract, closing
        showinfo("Success", message="The execution was successfully completed.")
        self.pb.stop()
        self.destroy()

：

def unzip_changes(self, delta_file_arr, inputARES):
    row            = 22 #used for GUI

    #debug
    self.debug_output("Unzip changes", row, "Start: ")

    tarfile_ARES = tarfile.open(inputARES)
    time_not_found = date.today().strftime("%Y-%m-%d")
    file_not_found = open(self.logs_path + time_not_found + '.log', 'w')

    #counters for progress bar
    self.counter    = 0
    self.maxcount   = 22000

    #extract
    for name in delta_file_arr:
        self.update_idletasks()
        self.counter +=1
        try:
            member      = tarfile_ARES.getmember(name)
            member.name = os.path.basename(member.name)
            result      = re.search("(.*).xml", member.name)
            res         = result.group(1)
            r           = res[:-1]
            num         = int(r)
            tarfile_ARES.extract(member, self.get_folder(num))
        except:
            result         = re.search("./VYSTUP/DATA/(.*).xml", name)
            res            = result.group(1)
            file_not_found.write(res + "\n")
            continue
    #after extract, closing
    self.pb.stop()
    showinfo("Success", message="The execution was successfully completed.")
    file_not_found.close()
    self.destroy()

您应该为要运行的每个功能使用线程，因为如果不这样做，则TKINTER窗口将冻结，直到功能完成为止。因此，请使用：

import threading

此处具有按钮的示例：

Button = tk.Button(text='Thread',command=lambda: threading.Thread(target=my_function).start())

如果使用类：

self.Button = tk.Button(self, text='Thread',command=lambda: threading.Thread(target=self.my_function).start())
