cos'è una tupla in python
# A tuple is a sequence of immutable Python objects. Tuples are
# sequences, just like lists. The differences between tuples
# and lists are, the tuples cannot be changed unlike lists and
# tuples use parentheses, whereas lists use square brackets.
tup1 = ('physics', 'chemistry', 1997, 2000);
tup2 = "a", "b", "c", "d";
# To access values in tuple, use the square brackets for
# slicing along with the index or indices to obtain value
# available at that index.
tup1[0] # Output: 'physics'tuple in python
my_tuple = 3, 4.6, "dog"
print(my_tuple)
# tuple unpacking is also possible
a, b, c = my_tuple
print(a) # 3
print(b) # 4.6
print(c) # dogtupla in python
#a tuple is basically the same thing as a
#list, except that it can not be modified.
tup = ('a','b','c')tuple in python
t = 12345, 54321, 'hello!'
print(t[0])
# output 12345
print(t)
# output (12345, 54321, 'hello!')
# Tuples may be nested:
u = t, (1, 2, 3, 4, 5)
print(u)
# output ((12345, 54321, 'hello!'), (1, 2, 3, 4, 5))
# Tuples are immutable:
# assigning value of 12345 to 88888
t[0] = 88888
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment
# but they can contain mutable objects:
v = ([1, 2, 3], [3, 2, 1])
print(v)
# output ([1, 2, 3], [3, 2, 1])Pagine correlate
