幫我修改代碼，我還需要它的内容表名稱寫在相應内容的前面，并且每一行都要循環加上import os import shutil from datetime import date src_folder = r"Y:\iplas\Robot_Log\SMT" dst_folder = r"D:\測試log" today = date.today() # create target folder if it does not exist if not os.path.exists(dst_folder): os.makedirs(dst_folder) # copy files and rename for file_name in os.listdir(src_folder): if file_name.endswith('.txt'): file_path = os.path.join(src_folder, file_name) if date.fromtimestamp(os.path.getmtime(file_path)) == today: new_file_name = f"{today.strftime('%Y%m%d')}_{file_name}" shutil.copy(file_path, os.path.join(dst_folder, new_file_name)) # write file contents with corresponding file names file_contents = [] for file_name in os.listdir(dst_folder): if file_name.endswith('.txt'): try: with open(os.path.join(dst_folder, file_name), 'r', encoding='gbk') as t: file_content = t.read().strip() file_contents.append(f"{new_file_name[:-4]},{file_content}") except Exception as e: print(f"Error reading file {file_name}: {e}") with open(os.path.join(dst_folder, '汇总文档.txt'), 'w', encoding='gbk') as f: f.write('\n'.join(file_contents))

請確認一下，我的理解是您希望在每一行前面加上文件名稱，並將最後生成的文件名稱改為 "汇总文档.txt"。如果我有誤解請告訴我，我會再次修改。

import os
import shutil
from datetime import date

src_folder = r"Y:\iplas\Robot_Log\SMT"
dst_folder = r"D:\測試log"
today = date.today()

# 創建目標文件夾（如果不存在）
if not os.path.exists(dst_folder):
    os.makedirs(dst_folder)

# 複製文件並重命名
for file_name in os.listdir(src_folder):
    if file_name.endswith('.txt'):
        file_path = os.path.join(src_folder, file_name)
        if date.fromtimestamp(os.path.getmtime(file_path)) == today:
            new_file_name = f"{today.strftime('%Y%m%d')}_{file_name}"
            shutil.copy(file_path, os.path.join(dst_folder, new_file_name))

# 寫入文件內容和相應文件名稱
file_contents = []
for file_name in os.listdir(dst_folder):
    if file_name.endswith('.txt'):
        try:
            with open(os.path.join(dst_folder, file_name), 'r', encoding='gbk') as t:
                file_content = t.read().strip()
                file_contents.append(f"{file_name[:-4]},{file_content}")
        except Exception as e:
            print(f"Error reading file {file_name}: {e}")

# 將文件名稱改為"汇总文档.txt"並寫入文件
with open(os.path.join(dst_folder, '汇总文档.txt'), 'w', encoding='gbk') as f:
    f.write('\n'.join(file_contents))

請你幫我修改，我只需要指定文件夾當天生產的txt文檔進行匯總，不需要這個文件夾以前的也複製import os import shutil from datetime import date src_folder = r"Y:\iplas\Robot_Log\SMT" dst_folder = r"D:\測試log" today = date.today() # 創建目標文件夾（如果不存在） if not os.path.exists(dst_folder): os.makedirs(dst_folder) # 複製文件並重命名 for file_name in os.listdir(src_folder): if file_name.endswith('.txt'): file_path = os.path.join(src_folder, file_name) if date.fromtimestamp(os.path.getmtime(file_path)) == today: new_file_name = f"{today.strftime('%Y%m%d')}_{file_name}" shutil.copy(file_path, os.path.join(dst_folder, new_file_name)) # 寫入文件內容和相應文件名稱 file_contents = [] for file_name in os.listdir(dst_folder): if file_name.endswith('.txt'): try: with open(os.path.join(dst_folder, file_name), 'r', encoding='gbk') as t: file_content = t.read().strip() file_contents.append(f"{file_name[:-4]},{file_content}") except Exception as e: print(f"Error reading file {file_name}: {e}") # 將文件名稱改為"汇总文档.txt"並寫入文件 with open(os.path.join(dst_folder, '汇总文档.txt'), 'w', encoding='gbk') as f: f.write('\n'.join(file_contents))

以下是修改后的代码，只会处理当天生成的文本文件：

import os
import shutil
from datetime import date

src_folder = r"Y:\iplas\Robot_Log\SMT"
dst_folder = r"D:\測試log"
today = date.today()

# 拼接当天的文件名
new_file_name = f"{today.strftime('%Y%m%d')}_汇总文档.txt"
new_file_path = os.path.join(dst_folder, new_file_name)

# 如果当天已经有汇总文档，则删除
if os.path.exists(new_file_path):
    os.remove(new_file_path)

# 遍历源文件夹中的文件
for file_name in os.listdir(src_folder):
    if file_name.endswith('.txt'):
        file_path = os.path.join(src_folder, file_name)
        # 如果文件是当天生成的，则复制到目标文件夹
        if date.fromtimestamp(os.path.getmtime(file_path)) == today:
            shutil.copy(file_path, dst_folder)

# 将源文件夹中当天生成的所有文件合并到汇总文档中
with open(new_file_path, 'w', encoding='gbk') as new_file:
    for file_name in os.listdir(dst_folder):
        if file_name.endswith('.txt'):
            file_path = os.path.join(dst_folder, file_name)
            # 如果文件是当天生成的，则将内容写入汇总文档中
            if date.fromtimestamp(os.path.getmtime(file_path)) == today:
                try:
                    with open(file_path, 'r', encoding='gbk') as t:
                        file_content = t.read().strip()
                        new_file.write(f"{file_name[:-4]},{file_content}\n")
                except Exception as e:
                    print(f"Error reading file {file_name}: {e}")

修改的主要点：

1. 删除了创建目标文件夹的代码，因为如果目标文件夹不存在，`shutil.copy` 方法会自动创建它。

2. 在循环遍历源文件夹中的文件时，直接将当天生成的文件复制到目标文件夹中，不需要先重命名再复制。

3. 在将所有文件合并到汇总文档时，只处理当天生成的文件。同时，使用 `with open(new_file_path, 'w', encoding='gbk') as new_file:` 打开汇总文档，这样在写入完毕后会自动关闭文件，不需要手动调用 `new_file.close()`。另外，每次写入一行时，需要加上换行符 `\n`。
