Pickle. Loads have bosses can explain how the relief of paramagnetic?-CodePudding

First of all, it loads only parse the data first, if the string of bytes is multiple data, the data behind the parsing,

More reasonable approach is to create a temporary file and loads, but here I want to know what really no more convenient method loads? Here tried two ways, one is each byte violence to try, one is the dump again, get the length, simulate the load of pointer,

But there is no method loads and returns a parsing length?

 
The import pickled 
F=b '\ x80 \ x04 \ x95 \ x07 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x8c \ x03123 \ x94 \ x80 \ x04 \ x95 \ x07 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x8c \ x03456 \ x94' 
For I in range (len (f)) : 
Try: 
J=pickle loads (f [I:]) 
Except: pass 
The else: print (j)
