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: python list of tuples
#List of Tuples
list_tuples = [('Nagendra',18),('Nitesh',28),('Sathya',29)]
#To print the list of tuples using for loop you can print by unpacking them
for name,age in list_tuples:
print(name,age)
#To print with enumerate--->enumerate is nothing but gives the index of the array.
for index,(name,age) in list_tuples:
#print using fstring
print(f'My name is {name} and age is {age} and index is {index}')
#print using .format
print('My name is {n} and age is {a} and index is {i}'.format(n=name,a=age,i=index))
Example 3: 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 4: tuple() python
example = [1, 2, 3, 4]
# Here is a list above! As we both know, lists can change in value
# unlike toples, which are not using [] but () instead and cannot
# change in value, because their values are static.
# list() converts your tuple into a list.
tupleexample = ('a', 'b', 'c')
print(list(tupleexample))
>> ['a', 'b', 'c']
# tuple() does the same thing, but converts your list into a tuple instead.
print(example)
>> [1, 2, 3, 4]
print(tuple(example))
>> (1, 2, 3, 4)
