Python-Copying a file into a folder present in a A.jar file without extracting

Hi ,
I was trying to copy a file into a A.jar (without extracting it) but it didn't work.
Suppose i have file copy.txt in D:\python\copy.txt and i want this file to be copied into my A.jar/org/here

for this I have written a code in python but what it is doing is , It is taking the contents of copy.txt and pasting the content to target dir-> A.jar/org/. It is not pasting the file instead it is pasting the content. I want the file to be copied with the content and if the file is already exist it will replace it in the target dir.
Please see my below code and suggest .

import zipfile, os

def show_jar_classes(jar_file):

zf = zipfile.ZipFile(jar_file, 'a')
try:
    #Code to write inside org folder in inside z.jar
    
    dir=input("please give the source file dir along with the file")# taking complete path frm user
    m='/'
    
    dir= dir.replace('\\',m) #formating the path by replacing '\' with '/'
    clas=os.path.basename(dir) #extracting the file name from the given path
    
    zf.write(dir, "org\\"+clas) #writing into A.jar/org/
finally:
    zf.close()

jar_file = 'D:/python/A.jar'
show_jar_classes(jar_file)

Extract to get A.jar.zip

首先使用提供的脚本、A.jar 和 copy.txt 重现该行为，然后检查 zipfile.ZipFile 调用和 zf.write 的条目名称。确认归档是否包含 org 下预期的文件条目，以及现有条目是否会被替换；当这一行为得到可靠演示时，该 issue 即可完成。
