Python 报错:ValueError: binary mode doesn't take an encoding argument 在运行文件操作相关功能时报错:ValueError: binary mode doesn't take an encoding argument 上代码: >>>fp = open("a.txt","rb+",encoding="utf-8")#rb+操作时不支持指定encoding参数Traceback (most recent call last): File"<st...
File "<stdin>", line 1, in <module> ValueError: binary mode doesn't take an encoding argument 原因分析:rb+操作时不支持指定encoding参数 解决办法: 去掉encoding,改成 with open('course_info','rb+') as f:

also put stdin, stdout and stderr in binary mode. Note that there is internal buffering in xreadlines(), readlines() and file-object iterators (for line in sys.stdin”) which is not influenced by this option. To work around this, ...

低于3 的 Python 版本中将二进制串也认为是常规字符串,而二进制串和字符串绑定到 SQL 类型为 BINARY 参数时,DM 数据库服务器内部处理不一样,因此,对于将二进制串直接绑定到 SQL 类型为 BINARY 参数的需求将无法满足,如将 BLOB 对象中读取的二进制串的绑定插入等。可以通过使用本函数,在低于 3 的 Python 版本...
fileinput.hook_compressed(filename,mode)使用给定的 encoding 和 errors 来读取文件。 从标准输入中读取 若input()不传任何参数时,fileinput默认会以stdin作为输入源。 运行stdinput.py后,在编译器中输入内容,程序会自动读取并再打印一次。 代码语言:javascript ...

Reading a file in “binary” mode? You’ll get a stream of bytes. Fetching a web page? Calling a web API? They return a stream of bytes, too. You need to understand your program. Thoroughly. Preferably because you wrote it, but at the very least, you need to be comfortable with ...
