Just add these lines to your script (the last one at the end):
from beancount.parser import printer
printer.print_entry(transaction1)
And the script will output:
2022-03-29 00:00:00 * "Bob's Grocery Store" "Groceries for the week"
Assets:Bank 1000 USD
Expenses:Groceries 200 USD
Just a note - I use the helpers in the data module to create the postings
like this:
data.create_simple_posting(entry, main_account,
number.D(f"{tx.amount:.2f}"), "USD")
This adds the posting to the entry (transaction1 in your script) and also
returns the posting as a convenience, if you need it.
I learned a LOT by digging through Red S's excellent code!
