解释原始二进制数据的输入并提取特定的值(Python)

该代码定义了函数process_binary_line.函数的作用是判断每一行是否有180个字符.如果不是，则引发ValueError,main循环捕获该错误，打印一条错误消息，并继续处理下一行.

函数main负责读取输入文件、处理每一行并将结果写入输出文件.

将此代码保存到一个Python文件(例如，process_binary.py)并运行它.它将提示您输入文件，按指定的方式处理数据，并将结果保存到processed_output.txt.

这是代码，请根据您的需要进行更改.

def process_binary_line(line):
    if len(line) == 180:
        return line[30:-30]
    else:
        raise ValueError("Each line should be 180 characters long.")

def main():
    filename = input("What is the name of your file: ")

    try:
        with open(filename, "r") as file:
            lines = file.readlines()

        processed_lines = []

        for line_number, line in enumerate(lines, start=1):
            try:
                processed_line = process_binary_line(line.strip())
                processed_lines.append(processed_line)
            except ValueError as e:
                print(f"Error in line {line_number}: {e}")
                continue

        output_filename = "processed_output.txt"

        with open(output_filename, "w") as output_file:
            for processed_line in processed_lines:
                output_file.write(processed_line + "\n")

        print(f"Processed data saved to {output_filename}")

    except FileNotFoundError:
        print(f"Error: File '{filename}' not found.")

if __name__ == "__main__":
    main()
