>From what you post it seems like you are on a Linux kind of system and you are running the `calendar` command in the bash terminal. If that is correct, try the following:

In the bash terminal type (without the literal #):
# python 

This will put you in the Python prompt (marked with >>>).
Check that the first line starts with Python 3. If not, I highly recommend
you install Python 3. If it is Python two, the following will work, but you
have to drop the outer parentheses for print (thus print calendar.calendar()) 

Then type the following:
>>> import calendar
>>> print(calendar.calendar(2020))

This will show:
                                  2020

Now look at the documentation of the calendar module to find out about
other options.
