The next command returns an empty string too.
(gdb) py print('>' + gdb.execute('next', to_string=True) + '<')
4 return 0;

And it seems this is a regression because lower versions of gdb can return the
output, but version 8.2 I'm using return empty string

This checkpoint code is kind of lame (and also maybe unsupported).
Anyway you can get the effect you want using from_tty:
(gdb) python x = gdb.execute('checkpoint',from_tty=True,to_string=True)
(gdb) python print(x)
checkpoint 1: fork returned pid 1581941.
I'm going to close this ticket.
