Python Utility Functions and Main Function Integration

This code defines several Python built-in library functions, including reading files, writing files, getting random numbers, getting the current time, and converting data to JSON format. The main function combines these functions together.

Technology Stack : The package and technology stack used in this code include os, sys, time, json, random, file I/O operations, random number generation, time operations, and JSON data conversion.

Code Type : Function

Code Difficulty :

                
                    
import os

def convert_to_json(data):
    """
    将数据转换为JSON格式。
    """
    return json.dumps(data)

def main():
    # 示例：读取一个文件，写入到一个新文件，获取随机数，获取当前时间，将数据转换为JSON格式
    file_content = read_file('example.txt')
    write_file('new_example.txt', file_content)
    random_number = get_random_number(1, 100)
    current_time = get_current_time()
    json_data = convert_to_json({'time': current_time, 'number': random_number})

    # 输出JSON数据
    print(json_data)

# 调用main函数
if __name__ == '__main__':
