Summary of Changes
Hello @ShaharNaveh, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request refines the sys.platform constant within the sys module to provide more accurate and distinct operating system identification. It separates Android from the generic Linux classification and introduces specific support for iOS, ensuring better compatibility and alignment with standard Python behavior on mobile platforms.
Highlights
- Android Platform Identification: The
sys.platformconstant has been updated to return'android'when the code is compiled for an Android target operating system. Previously, Android targets were identified as'linux', aligning with Python 3.13's updated behavior forsys.platform. - iOS Platform Support: New conditional compilation logic has been introduced to correctly identify and return
'ios'for thesys.platformconstant when the code is compiled for an iOS target.

Code Review
This pull request updates sys.platform to return 'android' on Android devices and 'ios' on iOS devices, aligning with CPython 3.13 and 3.9 specifications respectively. The implementation correctly uses conditional compilation flags. My main feedback is to suggest adding test cases to Lib/test/test_sys.py to cover these new platforms, which will help ensure correctness and prevent future regressions.

This change correctly implements the sys.platform value for Android and iOS, aligning with modern CPython behavior. To ensure these changes are validated and to prevent future regressions, it would be beneficial to add corresponding test cases in Lib/test/test_sys.py.
For example, you could add checks similar to existing ones for other platforms in SysModuleTest.test_thread_info:
# In Lib/test/test_sys.py
elif sys.platform == "android":
# assertions for android
elif sys.platform == "ios":
# assertions for iosAdding tests would improve the robustness of this change.

Ok, unlike this link, it is finally changed!
Starting from 3.13,
sys.platformnow returns 'android' if running on an android device. See notes at https://docs.python.org/3/library/sys.html#sys.platformAdded "ios" support as well
