Python Exercise 4: Tuples

Use the correct syntax to print the first item in the fruits tuple.
fruits = (“apple”, “banana”, “cherry”)
Use the correct syntax to print the number of items in the fruits tuple.
fruits = (“apple”, “banana”, “cherry”)
Use negative indexing to print the last item in the tuple.
fruits = (“apple”, “banana”, “cherry”)
Use a range of indexes to print the third, fourth, and fifth item in the list.
fruits = (“apple”, “banana”, “cherry”, “orange”, “kiwi”, “melon”, “mango”)

Python

Everything in Python is an object, including lists. All objects have a header of some sort in the C implementation.

Lists and other similar builtin objects with a "size" in Python, in particular, have an attribute called ob_size, where the number of elements in the object is cached. So checking the number of objects in a list is very fast.

But if you're checking if list size is zero or not, don't use len - instead, put the list in a boolean context - it treated as False if empty, True otherwise.

len(s)

Return the length (the number of items) of an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary, set, or frozen set).

len is implemented with __len__, from the data model docs:

object.__len__(self)

Called to implement the built-in function len(). Should return the length of the object, an integer >= 0. Also, an object that doesn’t define a __nonzero__() [in Python 2 or __bool__() in Python 3] method and whose __len__() method returns zero is considered to be false in a Boolean context.

And we can also see that __len__ is a method of lists:

items.__len__()

returns 3.

In this tutorial, we will learn about the Python List count() method with the help of examples.

The count() method returns the number of times the specified element appears in the list.

Example

# create a list numbers = [2, 3, 5, 2, 11, 2, 7]

# check the count of 2 count = numbers.count(2)

print('Count of 2:', count) # Output: Count of 2: 3

In this tutorial, we'll learn everything about Python lists: creating lists, changing list elements, removing elements, and other list operations with the help of examples.

A list in Python is implemented to store the sequence of various types of data. However, there are six data types in Python that are capable of storing the sequences but the most common and reliable type is a list. To learn more about python you can join our Master Python programming course.

A list is defined as a collection of values or items of different types. The items in the list are separated with a comma (,) and enclosed with the square brackets [].

It is defined as follows:

list1 = ['edureka', 'python', 2019]; list2 = [1, 2, 3, 4, 5 ]; list3 = ["a", "b", "c", "d"];
