[Python] How to compile Python code into byte code and the run it?

For example imagine I have myfile.py.
Sample code:

a = 6
b = 4
print(a+b)


So how can I convert this into bytecode?

I tried this:

source_code = '''a = 6
b = 4
print(a+b)'''
compiled_code = compile(source_code, '<string>', 'exec')
print(compiled_code.co_code)


Result:

b'\x97\x00d\x00Z\x00d\x01Z\x01\x02\x00e\x02e\x00e\x01z\x00\x00\x00\xa6\x01\x00\x00\xab\x01\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00d\x02S\x00'
​

It does give me a bytecode, but when I run it using exec(), it results in this error.

Traceback (most recent call last):
File "c:\Users\Dimuth De Zoysa\Desktop\Python_projects\OBftestcode.py", line 2, in <module>
exec(compiled_code.co_code)
ValueError: source code string cannot contain null bytes
