Suppose you have a text file, be it source code or poetry, but you don’t know its encoding. How do you detect the actual encoding? The next section answers that with a library recommendation. How to Discover the Encoding of a Byte Sequence How do you find the encoding of a byte sequ...
file:被打开的文件名称。 mode:文件打开模式,默认模式为r。 buffering:设置缓存模式。0表示不缓存,1表示缓存,如果大于1则表示缓存区的大小,以字节为单位。 encoding:字符编码。建议都带上参数encoding='UTF-8' afile=open("filetest.txt","w",encoding='UTF-8') afile.write("这里是要写到文件的内容") af...

Create a new directory at this given path. If mode is given, it is combined with the process’ umask value to determine the file mode and access flags. If the path already exists, FileExistsError is raised. If parents is true, any missing parents of this path are created as needed; the...

When no buffering argument is given, the default buffering policy works as follows: * Binary files are buffered in fixed-size chunks; the size of the buffer is chosen using a heuristic trying to determine the underlying device's "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`. ...
