Python搜索起始十六进制字符串，将之后的十六进制字符串保存到新文件中

source_file = open("source.txt", "r")
target_file = open("target.txt", "w")

source_content = source_file.read()

start_index = source_content.find("0x")

hex_string = source_content[start_index:]

target_file.write(hex_string)

source_file.close()
target_file.close()
