tuple definition 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: 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 3: what are tuples in python

#A tuple is essentailly a list with limited uses. They are popular when making variables 
#or containers that you don't want changed, or when making temporary variables.
#A tuple is defined with parentheses.

Example 4: make a tuple of any object in python

# tuple repitition works like this 
print(('Hi!',) * 4) # output: ('Hi!', 'Hi!', 'Hi!', 'Hi!')

Example 5: python tuple methods

count(x) : Returns the number of times 'x' occurs in a tuple
index(x) : Searches the tuple for 'x' and returns the position of where it was first found
