在日常编程工作中，我们常常需要处理各种与时间、数据格式及配置文件相关的问题。本文整理了一系列实用的Python代码片段，涵盖了日期时间转换、数据格式化与转换、获取文件注释以及读取配置文件等内容，助力开发者提升工作效率，轻松应对常见任务。

### 1. 秒级与毫秒级时间戳获取 ###

# 获取当前秒级时间戳
    def millisecond(add=0):
        return int(time.time()) + add
    # 获取当前毫秒级时间戳
    def millisecond_new():
        t = time.time()
        return int(round(t * 1000))

这两个函数分别提供了获取当前时间的秒级和毫秒级时间戳的功能。millisecond()函数允许传入一个可选参数add，用于增加指定的时间偏移量。

### 2. 当前日期字符串获取 ###

\# 获取当前时间日期: 20211009

def getNowTime(tianshu=0):
        shijian = int(time.strftime('%Y%m%d')) - tianshu
        print(shijian)
        return shijian

getNowTime()函数返回当前日期（格式为YYYYMMDD），并支持传入参数tianshu以减去指定天数。该函数适用于需要处理日期型数据且仅关注年月日的情况。

### 3. 修复接口返回无引号JSON数据 ###

def json_json():
        with open("源文件地址", "r") as f, open("目标文件地址", "a+") as a:
            a.write("{")
            for line in f.readlines():
                if "[" in line.strip() or "{" in line.strip():
                    formatted_line = "'" + line.strip().replace(":", "':").replace(" ", "") + ","
                    print(formatted_line)  # 输出修复后的行
                    a.write(formatted_line + "\n")
                else:
                    formatted_line = "'" + line.strip().replace(":", "':'").replace(" ", "") + "',"
                    print(formatted_line)  # 输出修复后的行
                    a.write(formatted_line + "\n")
            a.write("}")

此函数用于处理从接口复制的未正确格式化的JSON数据，修复缺失的引号，并将其写入新的文件。源文件与目标文件的路径需替换为实际路径。

### 4. 将URL查询字符串转为JSON ###

from urllib.parse import urlsplit, parse_qs
    def query_json(url):
        query = urlsplit(url).query
        params = dict(parse_qs(query))
        cleaned_params = {k: v[0] for k, v in params.items()}
        return cleaned_params

query\_json()函数接收一个包含查询字符串的URL，解析其查询部分，将其转换为字典形式，并清理多值参数，只保留第一个值。

### 5.文件注释提取 ###

import os
    def get_first_line_comments(directory, output_file):
        python_files = sorted([f for f in os.listdir(directory) if f.endswith('.py') and f != '__init__.py'])
        comments_and_files = []
        for file in python_files:
            filepath = os.path.join(directory, file)
            with open(filepath, 'r', encoding='utf-8') as f:
                first_line = f.readline().strip()
                if first_line.startswith('#'):
                    comment = first_line[1:].strip()
                    comments_and_files.append((file, comment))
        with open(output_file, 'w', encoding='utf-8') as out:
            for filename, comment in comments_and_files:
                out.write(f"{filename}: {comment}\n")
    # 示例用法
    get_first_line_comments('指定文件夹', '指定生成文件路径.txt')
    get_first_line_comments()函数遍历指定目录下的.py文件，提取每份文件的第

一行注释（以\#开头），并将文件名与注释对应关系写入指定的文本文件中。

### 6.读取配置INI文件 ###

import sys
    import os
    import configparser
    class ReadConfig:
        def __init__(self, config_path):
            self.path = config_path
        def read_sqlConfig(self, fileName="sql.ini"):
            read_mysqlExecuteCon = configparser.ConfigParser()
            read_mysqlExecuteCon.read(os.path.join(self.path, fileName), encoding="utf-8")
            return read_mysqlExecuteCon._sections
        def read_hostsConfig(self, fileName="hosts.ini"):
            read_hostsCon = configparser.ConfigParser()
            read_hostsCon.read(os.path.join(self.path, fileName), encoding="utf-8")
            return read_hostsCon._sections
    # 示例用法
    config_reader = ReadConfig('配置文件所在路径')
    sql_config = config_reader.read_sqlConfig()
    hosts_config = config_reader.read_hostsConfig()["hosts"]

ReadConfig类封装了对INI配置文件的读取操作，支持读取sql.ini和hosts.ini文件。通过实例化该类并指定配置文件路径，即可方便地获取所需配置信息。

### 7.设置全局文件路径 ###

import os
    def setFilePath(filePath):
        current_module_path = os.path.dirname(os.path.abspath(__file__))
        project_root_path = os.path.dirname(os.path.dirname(current_module_path))
        path = os.path.join(project_root_path, filePath.lstrip('/'))
        return os.path.abspath(path)
    # 示例用法
    confPath = setFilePath("地址文件路径")

setFilePath()函数根据提供的相对路径，结合当前模块的绝对路径，计算出项目根目录下的目标文件或目录的绝对路径，便于在项目中统一管理资源位置。
