New submission from Sidhant Bansal <sidhban...@gmail.com>:
The following code
```
import csv
with open("abc.csv", "w") as f:
data = [b'\xc2a9', b'\xc2a9']
w = csv.writer(f)
w.writerow(data)
```
writes "b'\xc2a9',b'\xc2a9'" in "abc.csv", i.e the b-prefixed byte string
instead of the actual bytes.
Although one can argue that the write is done in text mode and not binary mode,
however I believe the more natural expectation by the user will be to have the
bytes written actually in the "abc.csv".
Can refer to this https://github.com/pandas-dev/pandas/issues/9712 to see one
of the issues this brings in Pandas. From the discussion on this issue, the
main reasons of changing this behaviour in Python would be to avoid leaking
python's encoding system syntax into a generic data exchange format, i.e CSV.
