पायथन समारोह में अनुमत वर्ण

Question

क्या वर्णमाला वर्णों, संख्याओं और अंडरस्कोर को छोड़कर पाइथन फ़ंक्शन नामों में कोई अन्य अनुमत वर्ण हैं? यदि हां, तो वो कौन हैं?

Answer 1

पायथन 2.x में नहीं। the docs से:

identifier ::= (letter|"_") (letter | digit | "_")* 
letter  ::= lowercase | uppercase 
lowercase ::= "a"..."z" 
uppercase ::= "A"..."Z" 
digit  ::= "0"..."9" 

In Python 3 it's expanded:

identifier ::= xid_start xid_continue* 
id_start  ::= <all characters in general categories Lu, Ll, Lt, Lm, Lo, Nl, 
        the underscore, and characters with the Other_ID_Start property> 
id_continue ::= <all characters in id_start, plus characters in the categories 
        Mn, Mc, Nd, Pc and others with the Other_ID_Continue property> 
xid_start ::= <all characters in id_start whose NFKC normalization 
        is in "id_start xid_continue*"> 
xid_continue ::= <all characters in id_continue whose NFKC normalization 
        is in "id_continue*"> 

The Unicode category codes mentioned above stand for: 

Lu - uppercase letters 
Ll - lowercase letters 
Lt - titlecase letters 
Lm - modifier letters 
Lo - other letters 
Nl - letter numbers 
Mn - nonspacing marks 
Mc - spacing combining marks 
Nd - decimal numbers 
Pc - connector punctuations 
Other_ID_Start - explicit list of characters in PropList.txt 
       to support backwards compatibility 
Other_ID_Continue - likewise
