comments included while parsing requirements.txt

[AmmarRabie]

requirements.txt file allowing adding comments using "#" symbol. all these comments should be ignored when parsing and reading the file.

from the docs:

The requirements file format is closely tied to a number of internal details of pip (e.g., pip’s command line options). The basic format is relatively stable and portable but the full syntax, as described here, is only intended for consumption by pip, and other tools should take that into account before using it for their own purposes.

this result in not correct package version.
for example, if I have requirements.txt like that:

aiohttp==3.8.1  # UnwantedComment

the spdx will be:

PackageName: aiohttp
SPDXID: SPDXRef-1-aiohttp
PackageVersion: 3.8.1  # UnwantedComment
PrimaryPackagePurpose: APPLICATION
PackageSupplier: NOASSERTION
PackageDownloadLocation: NOASSERTION
FilesAnalyzed: false
PackageLicenseDeclared: NOASSERTION

PackageCopyrightText: NOASSERTION
ExternalRef: PACKAGE-MANAGER purl pkg:pypi/aiohttp@3.8.1  # UnwantedComment
