Anyone please help me how to download calender library using pip from
command prompt as i get
install icalender

The usual incantation looks like:

 python3 -m pip install icalendar

You might need to adjust “python3” to your python command.

Defaulting to user installation because normal site-packages is not writeable

This message is normal. You want a "user installation.

ERROR: Could not find a version that satisfies the requirement icalender (from versions: none)
ERROR: No matching distribution found for icalender

This means it could not find a suitable version of icalendar. What
version of python are you using? Starting the interactive Python
interpreter should recite that information.

Please show us the entire error output and the full command (including
your prompt).

You can get more information from pip with the -v option, eg:

 python3 -m pip install -vvv icalendar

which is quite verbose. Maybe just -v.
