Sending emails using Python can be accomplished with the built-in smtplib library. And tkinter for interface.

The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won’t. But what if we want to do something else if the condition is false. Here comes the else statement. We can use the else statement with if statement to execute a block of code when the condition is false.

Variables need not be declared first in python. They can be used directly. Variables in python are case-sensitive as most of the other programming languages.

For loops are used for sequential traversal. For example: traversing a list or string or array etc. In Python, there is no C style for loop, i.e., for (i=0; i<n; i++). There is “for in” loop which is similar to for each loop in other languages. Let us learn how to use for in loop for sequential traversals.

While loop is used to execute a block of statements repeatedly until a given condition is satisfied. And when the condition becomes false, the line immediately after the loop in the program is executed.

A string is a sequence of characters. A character is simply a symbol.

Lists store an ordered collection of items which can be of different types. The key difference between the tuples and lists is that while the tuples are immutable objects the lists are mutable. This means that tuples cannot be changed while the lists can be modified. Tuples are more memory efficient than the lists.

Dictionary in Python is a collection of keys values, used to store data values like a map, which, unlike other data types which hold only a single value as an element.

Python also accepts function recursion, which means a defined function can call itself.

A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. A function can return data as a result.

A class is a user-defined blueprint or prototype from which objects are created. Classes provide a means of bundling data and functionality together.

Constructors are generally used for instantiating an object. The task of constructors is to initialize(assign values) to the data members of the class when an object of the class is created. In Python the __init__() method is called the constructor and is always called when an object is created.

Python documentation strings (or docstrings) provide a convenient way of associating documentation with Python modules, functions, classes, and methods.

The __str__ method in Python represents the class objects as a string – it can be used for classes.

Inheritance is the capability of one class to derive or inherit the properties from another class.

There are several built-in modules in Python, which you can import whenever you like. (Eg: Random, DateAndTime..)

One way Problem solvers code solutions faster in Python faster than coding solutions in other programming languages is that Python is easy to learn and use. Python programs tend to be shorter and quicker to write than a program which completes a similar function in another languages.

Composition enables you to reuse code by adding objects to other objects, as opposed to inheriting the interface and implementation of other classes.

In Python, A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended.
