People should probably click before downvoting... this is what it looks like in the README:
from lithops import FunctionExecutor
def hello(name):
return f'Hello {name}!'
with FunctionExecutor() as fexec:
f = fexec.call_async(hello, 'World')
print(f.result())
If you copy/paste it the indentation is correct, it's just the display formatting for some reason.
