After reading this Python type casting topic, you will know its theory, examples, you will understand how to use various type casting functions as int(), float(), and str() in Python.
Type casting means to convert variable data of one type to another type and for doing this conversion some functions are available in python are:
After reading this Python String topic, you will understand how to write and manipulate the string, and you will understand how to + operator for string use in Python.
A group of characters is known as string. Characters that can be used in string as lowercase letters (a – z), uppercase letters (A – Z), digits (0 – 9) and other characters as (#, %, &, etc.).
After reading this Python lists topic, you will understand how to create the list, and you will know how to accessing Items, changing Items and use lists built-in methods in Python.
A list is a variable that collects same or different type of elements(items) in a sequence. The elements of the list can be changed.
After reading the Python Numbers topic, you will understand numbers and its classification as float, integer, and complex in Python.
In python, numbers are classified as
After reading this Python Sets topic, you will understand how to create the Set, and you will know how to accessing Items, changing Items and use Sets built-in methods in Python.
A set is a variable that collects same or different type of elements(items) does not exist in a sequence. The elements of the sets cannot repeat and set elements does not support index.
After reading this Python Dictionaries topic, you will understand how to create the dictionary, and you will know how to accessing Items, changing Items and use Python dictionary built-in methods.
A Dictionary is a variable that collects same or different type of elements(items) does not exist in a sequence. The elements of the dictionary cannot repeat and dictionary elements support key. Unlike an index which supports integer only, a key can support integer or string.
After reading this Python arrays topic, you will understand its the theory and examples, you will understand how to create the arrays, and you will know how to accessing Items, changing Items and use arrays built-in methods in Python.
An array is a variable that collects same type of elements in a sequence.
After reading this Python Tuples topic, you will understand its the theory and examples, you will understand how to create the tuples, and you will know how to accessing Items, changing Items and use tuples built-in methods in Python.
A tuple is a variable that collects same or different type of elements (items) in a sequence. The elements of the tuple cannot change.
After reading this Python Iterators topic, you will know how to implement an iterator and use a loop over an iterator in Python, you will understand iterator two methods __iter()__ and __next()__, & stopiteration statement in Python.
In python, an iterator is an object and iterator object is generally associated with two methods as __iter()__ and __next()__. Lists, tuples, dictionaries, sets, etc. all are examples of iterable objects. The object said to be iterable when it gives iterator and for doing this the object used the method __iter()__. The __next()__ method is used to visit each item of lists, tuples, dictionaries, sets, etc. in python.
After reading this Python Try Except topic, you will know its theory, examples and, you will understand Try-Many-Excepts, Try-Except-Else & Try-Except-Finally in Python.
In the beginning, statements within try block execute and if any exception occurs, program execution jumps to except block statements and start executes them.
