StringIO wrapper that more closely matches standard file behavior. This is a simple compatibility wrapper around the native StringIO class which fixes some corner-cases of its behavior. Specifically: adding __enter__ and __exit__ methods;Step 4: Download the historical stock prices. Iterate over each stock symbol and using yahoo finance API, download the daily stock prices between the start and end dates. Append all the individual stock info and create the analytical dataset. Also, note that some symbols may be unavailable to download, for which we have added the 'try' and ...Initial contents of file-like objects can be specified with string parameter (should be normal string for StringIO or bytes object for BytesIO). All the usual file methods like read(), write(), seek(), flush(), close() are available on these objects, and additionally, a following method: getvalue ¶The following code uses asynchronous iteration (line C) to read content from the stdout of a child process: Line A: We ignore stdin, want to access stdout via a stream and forward stderr to process.stderr. Line B: We await until echoReadable () is completely done.flush () ¶ Flush the write buffers of the stream if applicable.

There's a lot of other functions in the code, such as for example setAggregationMethod() , that mixes the handling of the files - even doing things like os.fsync() - while manipulating structured data.Flush() Clears all buffers for the current writer and causes any buffered data to be written to the underlying device. (Inherited from TextWriter) FlushAsync() Asynchronously clears all buffers for the current writer and causes any buffered data to be written to the underlying device.I am trying to redirect output, and flush every once in a while to clear the buffer.

If you are using Python 2, torch.save() does NOT support StringIO.StringIO as a validHow to use. In this document, some samples of the PyLZMA library will be given. First, we need to import the module. The easiest usage is compression and decompression in one step. >>> compressed = pylzma.compress ( 'Hello world!' ) >>> pylzma.decompress (compressed) 'Hello world!'.

That makes is easier to switch to cStringIO where initialized objects are read-only.In this example, the result printed after "all persons" will be the result of the second query (the list where salesrep='John Doe') and the result printed after "John Doe" will be empty.This happens because the underlying TDS protocol does not have client side cursors.
