how to create a tuple in python code example

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: tuple in python

#a tuple is basically the same thing as a
#list, except that it can not be modified.
tup = ('a','b','c')

Example 6: pyhton tuple

#It's like a list, but unchangeable
tup = ("var1","var2","var3")
tup = (1,2,3)
#Error
