pip install "wei-data-shu[analysis]"

# 需要通过本机 Excel 应用操作工作簿
pip install "wei-data-shu[excel-client]"

升级：

pip install --upgrade wei-data-shu

导入方式

from wei_data_shu.database import MySQLDatabase
from wei_data_shu.excel import ExcelManager
from wei_data_shu.files import FileManagement
from wei_data_shu.mail import DailyEmailReport
from wei_data_shu.text import DateFormat, StringBaba, TextAnalysis
from wei_data_shu.ai import ChatBot
from wei_data_shu.utils import fn_timer, generate_password, mav_colors, search_colors

命令行

安装后可直接使用：

wei-data-shu --help
python -m wei_data_shu --help

常用示例：

wei-data-shu colors
wei-data-shu colors mint
wei-data-shu colors 薄荷
wei-data-shu password --count 10 --length 13

5 分钟上手

下面这个示例不依赖数据库、邮件服务或本机 Excel，安装后可以直接运行。它会完成 4 件事：

• 生成当天报表文件名
• 创建一个 Excel 文件并写入示例数据
• 读取颜色表中的中文颜色信息
• 生成一个不含易混淆字符的安全密码

from pathlib import Path

from wei_data_shu.excel import ExcelManager
from wei_data_shu.text import DateFormat
from wei_data_shu.utils import generate_password, search_colors

today = DateFormat(interval_day=0, timeclass="date").get_timeparameter(Format="%Y-%m-%d")
report_path = Path(f"demo-report-{today}.xlsx")

rows = [
    ["日期", "渠道", "销售额"],
    [today, "电商", 12580],
    [today, "门店", 9680],
    [today, "分销", 7320],
]

with ExcelManager(str(report_path)) as wb:
    wb.write_sheet("日报", rows, start_row=1, start_col=1)
    summary = wb.read_sheet("日报", 1, 1)

mint_colors = search_colors("薄荷")
temp_password = generate_password(13)

print("报表文件：", report_path.resolve())
print("首行数据：", summary[0])
print("颜色搜索：", mint_colors[0]["hex"], mint_colors[0]["name"], mint_colors[0]["name_zh"])
print("临时密码：", temp_password)

运行后你会得到一个 demo-report-YYYY-MM-DD.xlsx 文件，并在终端看到类似输出：

报表文件： D:\path\to\demo-report-2026-03-17.xlsx
首行数据： ['日期', '渠道', '销售额']
颜色搜索： #5BC49F mint green 薄荷绿
临时密码： 8rY#FvQ7mK2$T

结构说明：

• 核心代码统一放在 wei_data_shu/ 包下；
• 根包通过 _api.py 统一维护公开导出，且根包只暴露领域包；
• 优先使用按领域划分的子包，如 wei_data_shu.excel、wei_data_shu.text、wei_data_shu.files；
• 测试代码放在 tests/，避免和发布包混在一起；
• 构建产物（build/、dist/、*.egg-info）不纳入版本控制。

用法示例

1. MySQLDatabase

用于快速连接 MySQL、执行 SQL、读取结果。

from wei_data_shu.database import MySQLDatabase

mysql_config = {
    "host": "your_host",
    "port": 3306,
    "user": "your_user",
    "password": "your_password",
    "database": "your_database",
}

db = MySQLDatabase(mysql_config)

insert_query = "INSERT INTO your_table (column1, column2) VALUES (%s, %s)"
insert_params = ("value1", "value2")
db.execute_query(insert_query, insert_params)

select_query = "SELECT * FROM your_table"
results = db.fetch_query(select_query)
for row in results:
    print(row)

update_query = "UPDATE your_table SET column1 = %s WHERE column2 = %s"
update_params = ("new_value", "value2")
db.execute_query(update_query, update_params)

delete_query = "DELETE FROM your_table WHERE column1 = %s"
delete_params = ("new_value",)
db.execute_query(delete_query, delete_params)

db.close()

如果你希望在数据库对象上直接启用 AI 聊天：

from wei_data_shu.database import MySQLDatabase

cfg = {
    "user": "root",
    "password": "你的密码",
    "host": "127.0.0.1",
    "port": 3306,
    "database": "mlcorpus",
}
db = MySQLDatabase(cfg)
db.run_ai_chatbot(chat_history_size=5, system_msg="System: You are a helpful AI assistant.")

2. Excel

Excel 相关能力分成 4 类：日常读写、快捷方法、Excel App 操作、高级文件处理。

推荐优先使用 ExcelManager。

from pathlib import Path
from wei_data_shu.excel import ExcelManager, ExcelHandler, OpenExcel, ExcelOperation, quick_excel, read_excel_quick

2.1 ExcelManager

from wei_data_shu.excel import ExcelManager

wb = ExcelManager("data.xlsx")

wb.write_sheet("Sheet1", [["Name", "Age"], ["Alice", 25]], start_row=1, start_col=1)
wb.fast_write("Sheet1", [["Bob", 30]], start_row=3, start_col=1)
data = wb.read_sheet("Sheet1", 1, 1)

with ExcelManager("data.xlsx") as wb:
    wb.fast_write("Sheet1", [[1, 2], [3, 4]], 1, 1)

wb.save()
wb.close()

DataFrame 支持：

import pandas as pd
from wei_data_shu.excel import ExcelManager

df = pd.DataFrame({"Name": ["Alice", "Bob"], "Age": [25, 30]})

with ExcelManager("data.xlsx") as wb:
    wb.write_dataframe("Sheet1", df)

with ExcelManager("data.xlsx") as wb:
    df = wb.read_dataframe("Sheet1")

工作表管理：

from wei_data_shu.excel import ExcelManager

wb = ExcelManager("data.xlsx")

wb.create_sheet("NewSheet")
info = wb.get_sheet_info("Sheet1")
print(info)
wb.copy_sheet("Sheet1", "Sheet1_Copy")
wb.delete_sheet("OldSheet")

2.2 quick_excel / read_excel_quick

from wei_data_shu.excel import quick_excel, read_excel_quick

wb = quick_excel("data.xlsx", [["Name", "Age"], ["Alice", 25]])
data = read_excel_quick("data.xlsx")
df = read_excel_quick("data.xlsx", as_dataframe=True)

2.3 ExcelHandler

from wei_data_shu.excel import ExcelHandler

eh = ExcelHandler("data.xlsx")

eh.excel_write("Sheet1", [[1, 2], [3, 4]], 1, 1, 2, 2)
data = eh.excel_read("Sheet1", 1, 1, 2, 2)
eh.excel_save_as("output.xlsx")
eh.excel_quit()

2.4 OpenExcel

适合需要通过本机 Excel 应用执行 RefreshAll() 等操作。 注意：需要安装 Microsoft Excel。

from wei_data_shu.excel import OpenExcel

with OpenExcel("data.xlsx").my_open() as wb:
    wb.fast_write("Sheet1", [[1, 2], [3, 4]], 1, 1)

with OpenExcel("data.xlsx").open_save_Excel() as appwb:
    appwb.api.RefreshAll()

sheets = OpenExcel("data.xlsx").file_show(filter=["sheet", "报表"])
print(sheets)

2.5 ExcelOperation

from wei_data_shu.excel import ExcelOperation

op = ExcelOperation("data.xlsx", "output_folder")
files = op.split_table()
op.merge_tables(["file1.xlsx", "file2.xlsx"], "merged.xlsx")
csv_path = op.convert_to_csv()

2.6 完整流水线示例

from pathlib import Path
from wei_data_shu.excel import ExcelManager, OpenExcel, ExcelOperation

base = Path.cwd()
f = str(base / "pipeline.xlsx")

with ExcelManager(f) as wb:
    wb.fast_write("Sheet1", [["Name", "Age"], ["Alice", 25], ["Bob", 30]], 1, 1)

with OpenExcel(f).open_save_Excel() as appwb:
    appwb.api.RefreshAll()

op = ExcelOperation(f, str(base / "output"))
op.split_table()

csv_file = op.convert_to_csv()

3. DailyEmailReport

用于发送纯文本或 HTML 邮件。

from wei_data_shu.mail import DailyEmailReport

email_reporter = DailyEmailReport(
    email_host="smtp.example.com",
    email_port=465,
    email_username="[e-mail]",
    email_password="your_password",
)

email_reporter.add_receiver("[e-mail]")

text_content = """
Hello,

Here is your daily report.

[Insert your report content here.]

Regards,
Your Name
"""
email_reporter.send_daily_report("Daily Report", text_content)

html_content = """
<html>
  <body>
    <h1>Daily Report</h1>
    <p>Hello,</p>
    <p>Here is your <b>daily report</b>.</p>
    <ul>
      <li>Item 1</li>

    </ul>
    <p>Regards,<br>
    Your Name</p>
  </body>
</html>
"""
email_reporter.send_daily_report("HTML Report", html_content, is_html=True)

4. DateFormat

用于快速生成日期、时间、时间戳，以及对 DataFrame 列进行格式化。

from wei_data_shu.text import DateFormat

x = DateFormat(interval_day=0, timeclass="date").get_timeparameter(Format="%Y-%m-%d")
print(x)

df = DateFormat(interval_day=0, timeclass="date").datetime_standar(df, "日期")

5. FileManagement

用于寻找最新目录、复制文件和批量重命名。

from wei_data_shu.files import FileManagement

FileManagement().copy_files(
    latest_folder2,
    destination_directory,
    target_files2,
    rename=True,
    file_type="xls",
)

latest_folder = FileManagement().find_latest_folder(base_directory)

6. StringBaba

用于字符串清洗和 SQL 拼接辅助。

from wei_data_shu.text import StringBaba

text = """
萝卜
白菜
"""
formatted_str = StringBaba(text).format_string_sql()

7. TextAnalysis

用于中文文本词频分析和词云绘制。

import pandas as pd
from wei_data_shu.text import TextAnalysis

data = {
    "Category": ["A", "A", "B", "D", "C"],
    "Text": [
        "我爱自然语言处理",
        "自然语言处理很有趣",
        "机器学习是一门很有前途的学科",
        "我对机器学习很感兴趣",
        "数据科学包含很多有趣的内容",
    ],
}

df = pd.DataFrame(data)
ta = TextAnalysis(df)
result = ta.get_word_freq(group_col="Category", text_col="Text", agg_func=" ".join)

word_freqs = result["word_freq"].tolist()
titles = result["Category"].tolist()
ta.plot_wordclouds(word_freqs, titles)

8. ChatBot

用于连接 Ollama 聊天接口。

from wei_data_shu.ai import ChatBot

bot = ChatBot(api_url="http://localhost:11434/api/chat")

print("开始聊天（输入 'exit' 退出，输入 'new' 新建聊天）")
while True:
    user_input = input("你: ")
    if user_input.lower() == "exit":
        break
    if user_input.lower() == "new":
        bot.start_new_chat()
        continue

    bot.send_message(user_input, stream=True)

9. Utils

提供通用计时器、调色板、密码生成和颜色搜索能力。

from wei_data_shu.utils import fn_timer, generate_password, mav_colors, search_colors

@fn_timer
def build_report():
    return "done"

result, elapsed = build_report()
print(result, elapsed)
print(generate_password())
print(mav_colors[:3])
print(search_colors("薄荷"))

颜色检索支持英文、HEX、中文关键字，并返回中英文名称：

from wei_data_shu.utils import search_colors

print(search_colors("mint"))
print(search_colors("薄荷"))
print(search_colors("#5BC49F"))

命令行查看颜色和生成密码：
