Iterating over sequences without comments results in comments from previous records

[telatin]

Using pyfastx version 0.8.4, I tried iterating over records but the "comment" attribute is not reset. Is there a safer way to iterate (I would like not to assume FASTA format) or did I just miss something obvious?

File (test.fa):

>1 comment
TTTTTTTT
>3
atatat

Code:

import pyfastx
fa = pyfastx.Fastx("test.fa")
for name,seq,comment in fa:
    print(comment)

Output:

comment
comment

Thanks for your help

Thank you for report this issue. But it was very strange. I have run your example on Windows and Ubuntu with Python 3.8.8 and pyfastx 0.8.4, the output of comment is right. Could you tell me your detailed system and python information.

Thanks for the quick reply. I used PyFastx 0.8.4.

I tried both on Python 3.6.9 |Anaconda, Inc.| (default, Jul 30 2019, 19:07:31), [GCC 7.3.0] on linux under Ubuntu 16.04.4 LTS, in a Miniconda environment, where pyfastx was also added via conda.

I also tried locally, using Python 3.9.1 [Clang 10.0.0 ] on darwin, also via Miniconda, but under macOS Big Sur.

I made a Dockerfile to test on a clean environment, see here
