Let's switch our focus to handling CSV files. We want to access the value of a specific column one by one. DictReader from the standard library seems to be an excellent candidate for this job. But what should we pass into X as an argument? According to the documentation, we should refer to the reader instance. So how do we bridge the gap between botocore.
StreamingBody type and the type required by the cvs module? We want to "convert" the bytes to string in this case. Therefore, the codecs module of Python's standard library seems to be a place to start. Since we are doing the opposite, we are looking for a "decoder," specifically a decoder that can handle stream data: codecs. The codecs. StreamReader takes a file-like object as an input argument. In Python, this means the object should have a read method. The botocore.
Since the codecs. StreamReader also supports the iterator protocol, we can pass the object of this instance into the csv. The final piece of the puzzle is: How do we create the codecs. That's where the codecs. We pass the codec of our choice in this case, utf-8 into the codecs. Viewed 3k times. Improve this question.
