BYTE_STREAM --o| FILE : contains } SOCKET { string host int port BYTE_STREAM --o| SOCKET : receives } 在这个ER图中,我们可以看到字节流(BYTE_STREAM)与文件(FILE)和Socket(SOCKET)之间的关系。 ByteStream+byteArray data+int length+decode()FileReader+string filePath+readBytes()SocketReader+string...

loads:可理解为load string,其功能是将json格式的字符串转换为Python数据类型(字典) load:读取json文件,将转换为Python类型 以下分别介绍其用法19.2.2.1 json.loadsloads常用用法如下所示:json.loads(str,encoding='utf8') 示例如下所示:import json jsonStr="""{ "book":"json in action", "author"...
from_what 可以省略,默认值为 0,表示以文件的开始作为参考点。>>> f = open('workfile', 'rb+') >>> f.write(b'0123456789abcdef') 16 >>> f.seek(5) # Go to the 6th byte in the file 5 >>> f.read(1) b'5' >>> f.seek(-3, 2) # Go to the 3rd byte before the end 13 ...
f.write(string) 将一个字符串写入文件,如果写入结束,必须在字符串后面加上"\n",然后f.close()关闭文件 四、文件中的内容定位f.read() 读取之后,文件指针到达文件的末尾,如果再来一次f.read()将会发现读取的是空内容,如果想再次读取全部内容,必须将定位指针移动到文件开始: f.seek(0) 这个函数的格式如下(...
