On Ubuntu 19.10, where python 2.7 is still the default, I get:

$ perf script report flamegraph
File "/usr/libexec/perf-core/scripts/python/", line 46
print(f"Flame Graph template {self.args.template} does not " +
SyntaxError: invalid syntax
Error running python script /usr/libexec/perf-core/scripts/python/

Installing libpython3-dev doesn't help.

$ perf script -s lang

Scripting language extensions (used in perf script -s [spec:]script.[spec]):

Perl [Perl]
pl [Perl]
Python [Python]
py [Python]

Should there be a python3 in that list?
