defopen(file, mode='r', buffering=None, encoding=None, errors=None, newline=None, closefd=True) 源码: 文件打开源码 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。
Do not open text files in binary mode unless you need to analyze the file contents to determine the encoding—even then, you should be using Chardet instead of reinventing the wheel (see “How to Discover the Encoding of a Byte Sequence”). Ordinary code should only use binary mode to ope...
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. On many systems, the buffer will typically be 4096 or 8192 bytes long. “Interactive”...
Line 4 calculates the sampling period, which is the time interval between audio samples in the file, as the reciprocal of the frame rate. Line 6 uses your window size and the sampling period to determine the frequencies in the audio. Note that the highest frequency in the spectrum will be...
