The S3 module is great, but it is very slow for a large volume of files- even a dozen will be noticeable. In addition to speed, it handles globbing, inclusions/exclusions, mime types, expiration mapping, recursion, cache control and smart directory mapping. Dec 31, 2016 · The io module implements the classes behind the interpreter’s built-in open() for file-based input and output operations. The classes are decomposed in such a way that they can be recombined for alternate purposes, for example to enable writing Unicode data to a network socket.

Introduction Have you ever received a PDF or an image file from someone via email, only to see strange characters when you open it? This can happen if your email server was only designed to handle text data. Files with binary data, bytes that represent non-text information like images, can be easily corrupted when being transferred and processed to text-only systems. Base64 encoding allows us

Hi I'm new to minio python sdk. I was trying to upload json to S3 using minio. According to API Reference, data argument accepts io.RawIOBase type. But it seems that data accepts io.BytesIO too which is not subclass of io.RawBaseIO. See this stackoverflow question. I also found that when I used io.StringIO instead of io.BytesIO, it fails. Python io module allows us to manage the file-related input and output operations. The advantage of using the IO module is that the classes and functions available allows us to extend the functionality to enable writing to the Unicode data. def _deserialize(self, data, type_): if self.compress: # decompress the data if needed data = lz4.frame.decompress(data) if type_ == _NUMPY: # deserialize numpy arrays buf = io.BytesIO(data) data = np.load(buf) elif type_ == _PICKLE: # deserialize other python objects data = pickle.loads(data) else: # Otherwise we just return data as it is (bytes) pass return data Mar 05, 2021 · Decode a JSON document from s (a str beginning with a JSON document) and return a 2-tuple of the Python representation and the index in s where the document ended.
