编写脚本exe1，该脚本接收一个命令行参数，并根据其类型做以下操作： • 若参数为普通文件，则显示其内容 • 若参数为压缩文件，则解压缩（如同目录下有同名文件则放弃） • 若参数为目录，则将其归档并压缩（如已有同名压缩文件则放弃） • 若参数不存在，给出错误提示并退出

编写一个名为 `exe1.py` 的Python脚本，可以实现这个功能。这里是一个基本的示例：

import os
import zipfile
import argparse

def read_file(file_path):
    with open(file_path, 'r') as f:
        return f.read()

def extract_zip(file_path, target_dir=None):
    try:
        with zipfile.ZipFile(file_path, 'r') as zip_ref:
            if not target_dir:
                target_dir = os.path.splitext(os.path.basename(file_path))[0]
            if os.path.exists(target_dir):
                print(f"Directory {target_dir} already exists, skipping extraction.")
            else:
                zip_ref.extractall(target_dir)
    except zipfile.BadZipFile:
        print(f"{file_path} is not a valid ZIP file.")

def compress_directory(directory_path, archive_name=None):
    try:
        if not archive_name:
            archive_name = os.path.basename(directory_path) + ".zip"
        with zipfile.ZipFile(archive_name, 'w', zipfile.ZIP_DEFLATED) as zipf:
            for root, dirs, files in os.walk(directory_path):
                for file in files:
                    zipf.write(os.path.join(root, file))
    except Exception as e:
        print(f"Error compressing directory: {e}")

def main():
    parser = argparse.ArgumentParser(description='Process command line arguments.')
    parser.add_argument('input', type=str, help='The input file or directory')

    args = parser.parse_args()
    
    input_path = args.input
    
    if os.path.isfile(input_path):
        print("Checking file content...")
        print(read_file(input_path))
    elif os.path.isdir(input_path):
        print("Compressing directory...")
        compress_directory(input_path)
    elif os.path.splitext(input_path)[1] in ['.zip', '.gz', '.rar']:  # Assuming common compression formats
        print("Extracting compressed file...")
        extract_zip(input_path)
    else:
        print(f"Invalid input: {input_path}. Please provide a file, directory, or a recognized compressed file.")

if __name__ == "__main__":
    main()

运行此脚本时，你可以通过命令行传入参数，例如：

python exe1.py /path/to/file.txt
python exe1.py /path/to/compressed.zip
python exe1.py /path/to/directory/
