可以在循环外部先创建一个空的列表，然后在循环中每次将json文件的名称添加到列表中。循环结束后再将列表中的元素写入到一个新的txt文件中即可。

示例代码如下：

import json 
import os 

# 指定原始数据集和目标路径
json_folder_path = "D:/python/pycharm/pycharm_date/Oracle/OracleCS/ce_shi_label"
txt_folder_path = "D:/python/pycharm/pycharm_date/Oracle/OracleCS/labels"

# 获取所有json文件的路径
json_files = [os.path.join(json_folder_path, f) for f in os.listdir(json_folder_path) if f.endswith('.json')]

# 创建空的列表
json_names = []

for json_file in json_files:
    # 打开json文件
    with open(json_file, 'r', encoding='utf-8') as f:
        data = json.load(f)
        image_name = data["img_name"] + ".jpg"
        label_name = data["img_name"]
        boxes = data["ann"] 
        
        # 将json文件名称添加到列表中
        json_names.append(label_name)
        
        # 将每个矩形框转换为txt格式
        txt_data = ""
        txt_line_1 = f"{label_name}\n"
        for box in boxes:
            x1, y1,x2, y2,class_id = str(box[0]), str(box[1]), str(box[2]),str(box[3]),str(box[4])
            txt_line =f"{x1} {y1} {x2} {y2} {class_id}\n"
            txt_data += txt_line 
        
        # 写入txt文件
        txt_file = os.path.join(txt_folder_path, image_name.replace(".jpg", ".txt"))
        with open(txt_file, 'w', encoding='utf-8') as f:
            f.write(txt_line_1 + txt_data)

# 将json文件名称写入新的txt文件中
json_names_file = os.path.join(txt_folder_path, "json_names.txt")
with open(json_names_file, 'w', encoding='utf-8') as f:
    for name in json_names:
        f.write(name + "\n")

这样，就可以将所有json文件的名称统一放在一个新的txt文件中了。
