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: 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

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 3: tuples in python
my_tuple = ("hello")
print(type(my_tuple)) # <class 'str'>
# Creating a tuple having one element
my_tuple = ("hello",)
print(type(my_tuple)) # <class 'tuple'>
# Parentheses is optional
my_tuple = "hello",
print(type(my_tuple)) # <class 'tuple'>
Example 4: how to use tupels python
tupel = ('banana',10,True)
print(tupel[2])
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)
