Copia di oggetti in Python
In qualche misura è la continuazione di questo post, anche se il titolo dev'essere completamente differente.
Esaurito il capitolo global ci sono ancora un paio di aspetti che a volte --se non faccio attenzione-- non vanno come --ingenuamente-- mi verrebbe da pensare; anche se... --OK, racconto.
Passando oggetti diversi da numeri a una funzione cosa succede? Devo elencarli nel return? o preoccuparmi del valore originale? Un esempio che chiarisce (dovrebbe, spero).
def func(i, f, ls, dic, st):
i = i * 2
f = f * 3
ls[0] = 'cambio'
ls[1] = 'qui'
dic['due'] = 2
st = st.upper() + ' modificata'
return i, f, st
# main
i = 4
f = 1.2
ls = [1, 2, 3, 4]
dic = {'uno' : 1}
st = 'stringa'
ir, fr, stm = func(i, f, ls, dic, st)
print(i, f)
print(ir, fr)
print(ls)
print(dic)
print(st)
print(stm)
eseguo e ottengo:
$ py3 obj.py
4 1.2
8 3.5999999999999996
['cambio', 'qui', 3, 4]
{'uno': 1, 'due': 2}
stringa
STRINGA modificata
$
Uh! vediamo in dettaglio:
- i valori originali delle variabili numeriche (i e f) non cambiano e i valori dell'elaborazione devo elencarli in return e tra quanto ritorna la funzione (ir e fr);
- la lista (ls) passata alla funzione viene modificata, e ritornata modificata, l'originale è perso;
- la stessa cosa capita per i dizionari (dic), le tuple, gli array, e altri oggetti (non presenti nell'esempio);
- le stringhe (che in certi linguaggi sono array, p.es C) si comportano come i numeri.
C'è un altra cosa che a volte... copiare oggetti. Ecco un esempio con le liste:
a = [1, 2, 3]
print(a)
b = a
b[0] = 'X'
print(a)
print(b)
$ py3 cp1.py
[1, 2, 3]
['X', 2, 3]
['X', 2, 3]
$
OOPS! la modifica di b ha modificato a! non quello che mi aspettavo. C'è il modulo copy per questo con due funzioni per copiare. Uso liste per gli esempi, ovviamente vale non solo per loro.
la funzione copy.copy() funziona solo per le liste lineari (non so se il termine è corretto), cosi:
import copy
a = [1, 2, 3]
print(a)
b = copy.copy(a)
b[1] = 'X'
print(a)
print(b)
$ py3 cp2-0.py
[1, 2, 3]
[1, 2, 3]
[1, 'X', 3]
$
ma non per liste dentro la lista:
import copy
a = [1, [2, 'a', 'b'], 3]
print(a)
b = copy.copy(a)
b[1][1] = 'X'
print(a)
print(b)
$ py3 cp2-1.py
[1, [2, 'a', 'b'], 3]
[1, [2, 'X', 'b'], 3]
[1, [2, 'X', 'b'], 3]
$
in questo caso devo ricorrere a copy.deepcopy()
import copy
a = [1, [2, 'a', 'b'], 3]
print(a)
b = copy.deepcopy(a)
b[1][1] = 'X'
print(a)
print(b)
$ py3 cp3.py
[1, [2, 'a', 'b'], 3]
[1, [2, 'a', 'b'], 3]
[1, [2, 'X', 'b'], 3]
$

Visibilità (scope) delle variabili - 1
Continuo da qui la serie di post elementari sui linguaggi con visibilità delle variabili lessicale e/o dinamica. Però ormai parlo di un argomento collegato, più personale, probabilmente interessa solo me.
Ah! una cosa in parte OT: mi sono letto i documenti citati in bibliografia da Ming-Ho (non tutti, confesso), avendo tempo ci sono cose interessanti, qualcuna la sapevo, altre meno. Ma il solito problema: il tempo.
Questo post arriva in cascata alla serie ma è diverso, forse sono solo io che ho fatto confusione, voglio chiarirmi un po' meglio come Python e JavaScript considerano le variabili, globali e locali. Un post molto semplice, didascalico, solo per me (probabilmente, come già detto).
Normalmente le variabili (numeriche, vedremo prossimamente che per gli oggetti valgono altre leggi) sono passate come valore alle funzioni e nel chiamante il loro valore non muta. Esempio, in Python:
def f():
print('f()', x)
return x
def g(n):
x = n
print('g()', n, f())
return f()
# main
x = 1
print('start x =', x)
print(x, f(), g(2), x, f())
x = 5
print('cambio x =', x)
print(x, f(), g(3), x, f())
$ py3 s-n.py
start x = 1
f() 1
f() 1
g() 2 1
f() 1
f() 1
1 1 1 1 1
cambio x = 5
f() 5
f() 5
g() 3 5
f() 5
f() 5
5 5 5 5 5
$
Stesso comportamento con JavaScript con l'avvertenza di definite con var le variabili locali, altrimenti sono globali:
function f() {
console.log('f()', x)
return x
}
function g(n) {
var x = n
console.log('g()', n, f())
return f()
}
// main
x = 1
console.log('start x =', x)
console.log(x, f(), g(2), x, f())
x = 5
console.log('cambio x =', x)
console.log(x, f(), g(3), x, f())
$ node s-n.js
start x = 1
f() 1
f() 1
g() 2 1
f() 1
f() 1
1 1 1 1 1
cambio x = 5
f() 5
f() 5
g() 3 5
f() 5
f() 5
5 5 5 5 5
$
OK, finora tutte le variabili sono locali (in realtà c'è la sola x in g()); Per operare con variabili globali in Python uso l'instruzione global globalmente, cioè esterna alle funzioni. Ma in questo caso il comportamento è diverso da come potrebbe apparire (è un errore!): la x in g() è locale:
global x
def f():
print('f()', x)
return x
def g(n):
x = n
print('g()', n, f())
return f()
# main
x = 1
print('start x =', x)
print(x, f(), g(2), x, f())
x = 5
print('cambio x =', x)
print(x, f(), g(3), x, f())
$ py3 s-ge.py
start x = 1
f() 1
f() 1
g() 2 1
f() 1
f() 1
1 1 1 1 1
cambio x = 5
f() 5
f() 5
g() 3 5
f() 5
f() 5
5 5 5 5 5
$
Risulta che il valore di x in g() non ha influenza su f() perché questa è globale e non relativa a g().
Per chiarire uno script ancora più focalizzato
global x
x = 1
def g(n):
print(x) # <- errore qui, x non è definita
x = n
print(x)
#main
g(2)
print(x)
eseguendola si ottiene un errore:
$ py3 gl.py
Traceback (most recent call last):
File "gl.py", line 10, in <module>
g(2)
File "gl.py", line 5, in g
print(x)
UnboundLocalError: local variable 'x' referenced before assignment
$
commentando la print iniziale in g() risulta come in g() x sia locale:
$ py3 gl.py
2
1
$
In JavaScript, dove le variabili sono globali di default:
function f() {
console.log('f()', x)
return x
}
function g(n) {
x = n // modif qui, x è globale
console.log('g()', n, f())
return f()
}
// main
x = 1
console.log('start x =', x)
console.log(x, f(), g(2), x, f())
x = 5
console.log('cambio x =', x)
console.log(x, f(), g(3), x, f())
$ node s-ge.js
start x = 1
f() 1
f() 2
g() 2 2
f() 2
f() 2
1 1 2 2 2
cambio x = 5
f() 5
f() 3
g() 3 3
f() 3
f() 3
5 5 3 3 3
$
OOPS! in questo caso la x in g() determina il valore di f(). Ho cioè un comportamento diverso per i due linguaggi, cosa che almeno per me induce errori se non si presta la dovuta attenzione. (Sì, sono ripetitivo).
Da sempre si usano variabili globali ma per quanto è possibile queste vanno limitate per quanto possibile. La variabile x in g() che voglio globale la dichiaro global all'interno della funzione; la chiamata a g() sarà diversa a quella ad h() dove x è locale. Peraltro diventa importante l'ordine delle chiamate:
def f():
print('f()', x)
return x
def g(n):
global x
x = n
print('g()', n, f())
return f()
def h(n):
x = n
print('h()', n, f())
return f()
# main
x = 1
print('start x =', x)
print(x, f(), g(2), x, f())
x = 5
print('cambio x =', x)
print(x, f(), g(3), x, f())
x = 8
print('cambio x =', x)
print(x, f(), h(4), g(3), x, h(6), f())
$ py3 s-gl.py
start x = 1
f() 1
f() 2
g() 2 2
f() 2
f() 2
1 1 2 2 2
cambio x = 5
f() 5
f() 3
g() 3 3
f() 3
f() 3
5 5 3 3 3
cambio x = 8
f() 8
f() 8
h() 4 8
f() 8
f() 3
g() 3 3
f() 3
f() 3
h() 6 3
f() 3
f() 3
8 8 8 3 3 3 3
$
JavaScript, per quanto precedentemente detto è in questo caso più intuitivo
function f() {
console.log('f()', x)
return x
}
function g(n) {
x = n // modif qui, x è globale
console.log('g()', n, f())
return f()
}
function h(n) {
var x = n // x è locale
console.log('h()', n, f())
return f()
}
// main
x = 1
console.log('start x =', x)
console.log(x, f(), g(2), x, f())
x = 5
console.log('cambio x =', x)
console.log(x, f(), g(3), x, f())
x = 8
console.log('cambio x =', x)
