Example 1: what is a tuple 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'
Example 2: changing tuple values
x = ("apple", "banana", "cherry")
y = list(x)
y[1] = "kiwi"
x = tuple(y)
print(x)
Example 3: tuples 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) # dog
Example 4: tuples 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])
Example 5: pyhton tuple
#It's like a list, but unchangeable
tup = ("var1","var2","var3")
tup = (1,2,3)
#Error
Example 6: tuples in python
# the tuples are like the Read-Only they are not to be changed or modified they're constant
letters = "a", "b", "c", "d" # you can use () as they are optional
print(letters)
"""
tuples are immutable but it's important because they don't returns the bugs
these are sequence types means you can iterate over them by it's index numbers
tuples data can't be changed but list's data can be changed
