I’d like to call exec in an async function and do something like the following code (which is not valid):
import asyncio async def f(): await exec('x = 1n' 'await asyncio.sleep(x)')
More precisely, I’d like to be able to wait for a future inside the code that runs in exec.
How can this be achieved?

Note: F-strings are only supported in python 3.6+. For older versions, use
%s
,.format()
or the classic+
concatenation.
async def aexec(code): # Make an async function with the code and `exec` it exec( f'async def __ex(): ' + ''.join(f'n {l}' for l in code.split('n')) ) # Get `__ex` from local variables, call it and return the result return await locals()['__ex']()
Known issues:
- If you use new lines in a string (triple quotes), it will mess up the formatting.
