Is there a man, the answer,,,

CodePudding user response:

Weight is integer

do you have any man, answer it,,,

% b is binary integer, and cannot be directly connected to the string, you need to use the STR function will he converted to string type value

The sentence is wrong, sorry, confused,
I run, error, the reason is ValueError: unsupported format character 'b' (0 x62) at 8 index
In simple terms, does not support % b this binary placeholder,
Change % d to decimal placeholder % d

Don't come to a junction points

Short answer:
For your screenshots of the error, my first feeling, and speculation (verified after, is also the reason is:

And problems caused by not is % b, because of my own after debugging the same code, know if % b, will be another different error:

 ValueError: unsupported format character 'b' (0 x62) at 9 index

And wouldn't be here:

 SyntaxError: invalid character identifier in

Solution:
The last Chinese parentheses, instead of the normal English parentheses,
That is:

 weight))

Instead of:

 weight))

Besides, the problem of % b:
And get rid of the inappropriate writing () should be changed to:

[remind] Python beginner developers matters needing attention: do not intentionally use error writing and should use the standard way right

I really want to, but don't understand to
