python - Execute large code snippet of string on one line

Question

I'm not able to find an answer to this for some reason - I'm looking to execute a large string code snippet as python code

For example the following code:

def multiply_num_by_5(num): 
    return 5*num 
multiply_num_by_5(4)

And now as one line: exec("def multiply_num_by_5(num): return 5*num print(multiply_num_by_5(4))")

However this returns a syntax error.

Is this possible to do (without modifying the string of code itself)? Is there a common parsing technique / library which allows running such code?

NOTE: I'm aware I can run the following. Here the print line is correctly indented. However this wouldn't be 'one line':

exec('''def multiply_num_by_5(num): return 5*num 
print(multiply_num_by_5(4))''')

Answer 1

Inserting a return character works for me

exec("def multiply_num_by_5(num): return 5*num
print(multiply_num_by_5(4))")
