I can create b-sting this way:
name_binary = b'Adam'
but if I have variable like name='Adam'
and I want to make at once usage of f-string and b-string:
name_binary = fb'{name}'
I get:
File "<input>", line 1
c = fb'{a}'
^
SyntaxError: invalid syntax
I know that I can do:
name_binary = name.encode('utf-8')
But technicality is that possible by using b and f together as on my example?
No, what you want has been proposed but rejected till now.
Read more about it in PEP-489:
No binary f-strings
For the same reason that we don't support
bytes.format()
, you may not combine'f'
with'b'
string literals.
The options you have (like you already mentioned) would be:
name_binary = f'{name}'.encode('utf-8')
or
name_binary = name.encode('utf-8')
