我们平时从网上下载一些文件，文件名很多都是一大串字母和数字，不打开看看，根本不知道里面是什么内容。

我想能不能做个工具，把我们一个文件夹下面的所有word、excel、ppt、pdf文件重命名为文件内容的第一行。

我们有些朋友可能不会编程，别慌，不会编程也没关系，我们可以让AI帮我们写一个Python程序。

下面我就让Kimi帮我们写一个程序：

我把上面这段代码复制到vscode中，把‘path_to_your_directory’替换成自己的文件夹路径，直接运行一下。

很不幸，报错了，没事，把错误提示复制出来，继续问Kimi：

再报错，再问：

你就不厌其烦的问。

AI的一个好处是他永远不会发脾气，哈哈，你只管问就行，不管你的问题有多白痴，它总是会耐心回答，也不会笑话你，这点AI比人类要强百倍。

最终AI给出了一个可运行的版本：

import os

from pdfminer.high_level import extract_text

def get_first_line_from_word(file_path):
    try:
        doc = Document(file_path)
        return doc.paragraphs[0].text if doc.paragraphs else ''
    except Exception as e:
        print(f"Error reading Word file {file_path}: {e}")
        return ''

def get_first_line_from_excel(file_path):
    try:
        wb = load_workbook(file_path)
        sheet = wb.active
        for row in sheet.iter_rows(min_row=1, values_only=True):
            for value in row:
                if value is not None:
                    return str(value)
        return ''
    except Exception as e:
        print(f"Error reading Excel file {file_path}: {e}")
        return ''

def get_first_line_from_ppt(file_path):
    try:

        for slide in presentation.slides:
            for shape in slide.shapes:
                if hasattr(shape, 'text') and shape.text:
                    return shape.text[:shape.text.index('\n')] if '\n' in shape.text else shape.text
        return ''
    except Exception as e:

    try:
        text = extract_text(file_path)
        return text.split('\n', 1)[0] if text else ''
    except Exception as e:
        print(f"Error reading PDF file {file_path}: {e}")
        return ''

def rename_files(directory):
    for filename in os.listdir(directory):
        if filename.lower().endswith(('.docx', '.xlsx', '.pptx', '.pdf')) and not filename.lower().startswith('.~') :
            file_path = os.path.join(directory, filename)
            first_line = ''
            if filename.lower().endswith('.docx'):
                first_line = get_first_line_from_word(file_path)
            elif filename.lower().endswith('.xlsx'):
                first_line = get_first_line_from_excel(file_path)
            elif filename.lower().endswith('.pptx'):
                first_line = get_first_line_from_ppt(file_path)
            elif filename.lower().endswith('.pdf'):
                first_line = get_first_line_from_pdf(file_path)
            
            if first_line:
                new_filename = first_line.strip() + os.path.splitext(filename)[1]
                new_file_path = os.path.join(directory, new_filename)
                os.rename(file_path, new_file_path)
                print(f"Renamed {filename} to {new_filename}")
            else:
                print(f"No first line found for {filename}")

# Specify the directory containing the files
directory = '/Users/zhan/Documents/test'  # Replace with the path to your directory
rename_files(directory)

运行效果如下：

我们还需要一个UI界面，让我们可以在图形界面上操作，我们继续问Kimi：

最终代码如下：

                os.rename(file_path, new_file_path)
                print(f"Renamed {filename} to {new_filename}")
            else:
                print(f"No first line found for {filename}")


# Specify the directory containing the files
directory = '/Users/zhan/Documents/test'  # Replace with the path to your directory      


# 这里是之前定义的rename_files函数和子函数
def choose_directory():
    directory = filedialog.askdirectory()
    if directory:
        entry.delete(0, tk.END)
        entry.insert(0, directory)

def rename_files_with_ui():
    directory = entry.get()
    if not directory:
        messagebox.showerror("错误", "请选择一个文件夹")
        return
    if not os.path.isdir(directory):
        messagebox.showerror("错误", "所选路径不是一个文件夹")
        return
    try:

        messagebox.showinfo("完成", "文件重命名完成")
    except Exception as e:
        messagebox.showerror("错误", f"发生错误: {e}")


# 创建主窗口
root = tk.Tk()
root.title("文件批量重命名工具")

# 创建一个标签和输入框用于显示选择的文件夹路径
label = ttk.Label(root, text="请选择文件夹:")
label.pack()
entry = tk.Entry(root, width=30)
entry.pack()

# 创建一个按钮，点击时弹出选择文件夹的对话框
browse_button = ttk.Button(root, text="浏览", command=choose_directory)
browse_button.pack()

# 创建一个按钮，点击时执行重命名操作
rename_button = ttk.Button(root, text="确定", command=rename_files_with_ui)
rename_button.pack()

# 设置窗口的尺寸
width = 350  # 宽度
height = 200  # 高度

# 获取屏幕的宽度和高度
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()

# 计算窗口的中心坐标
x = (screen_width / 2) - (width / 2)
y = (screen_height / 2) - (height / 2)

# 将窗口放置在屏幕中心
root.geometry(f'{width}x{height}+{int(x)}+{int(y)}')

# 运行主循环
root.mainloop()

我们看下运行效果：

试了一下，功能和上面的程序是一样的。

最后一步就是打包程序了，同样我们问下AI：

一共就两步：

1. 安装PyInstaller

pip install pyinstaller

2. 使用PyInstaller打包

pyinstaller --onefile --windowed file_renamer_gui.py

注意要把“file_renamer_gui.py"替换成你自己的文件名。

打包好之后，在项目目录的dist文件夹下就可以找到打包好的文件。

双击打开即可运行，效果是一样的。

好了，这个工具就写好了。

有了AI的助攻，我们想写什么工具直接让AI帮我们写就好了，是不是给了你很大的信心？

原来编程也不难，编程我也会啊~
