Python 3, be a paid scripting professional

Python installation can be a challenge by itself for some users. We will learn to install python as well as look at different IDE for write our scripts. WE will use Eclipse in this series. Eclipse is free and cross platform, available for WINDOWS, MAC and LINUX.

Python syntax might look a little Odd to the first time user. It has no braces to wrap up the code, we also have to take care of white spaces and indentation.

Python allows you write code that can make decisions based on true or false situation of the event. A straight forward code is not the code that we write in any situation. Let's have a close look in conditionals in python.

Python is very strict with some datatypes and sloppy with some. Some can be changed on the go while others need to be stick around, throughout the entire course of program.

Python numbers are easy to use. You will be dealing with lots of number and their calculation in python. Fortunately, python is very easy and powerful to handle numbers.

Python is the most among the most powerful language that can handle and perform countless operations on python. What you are thinking to do with strings, is already being done and there is a default function out there.

Python is very rich in data types. Python List ,tuples and dictionary is among them. These data types allows you to add more flexibility to the code and makes programmers life easy.

Python don't have switch and case. But this not the limitation of the language. We can work around, if we need switch and case. Lets use dictionary and create a swith and case sinario.

Python has got all the looping features. While loop is among one of them. In this movie, we will print a very basic fibonacci series using the while loop.

Python is little tricky with for loop and adds a few advantage in the for loop. For loop is very smart in python and is known as for each loop. It automatically tracks the counter for you. Basically, it is now more easy to loop through any item, it may be strings or array.

python gives us some loop control keywords. Break allows you to jump out of the loop while continue allows you to skip a few executions of the loop. Both should have a condition to match, in order to get in action.

Python allows you to perform various operations on numbers. Operations like addition, subtraction, modulus , multiplication are easy to handle. Just to get firiendly, use IDLE to quickly go through with these operations.

Python allows you to check multiple condition and deduce one boolean result from it. This can be done using AND and OR operations in python. Also range is among the top most useful function in the python.

Python, being an object oriented programming language, takes strings very seriously. Immense power is being added for the strings in the form of function. Fortunately, eclipse gives us an entire over view for that.

Python is fully capable to join and split string and this one of those common operation that you will be doing very often. This python tutorial will discuss about python join and split for the strings.

Python allows you to handle ordinary files such as text files very easily. Since everything is an object, it is very easy to open and file and perform operations like read, write and append.

Python also allows you to handle binary files such as Image files. You will have to take care a little about buffer size in this case. But gradually you will get into the habit of it. There are many third party libraries for it also.

Python take cares for error nicely. You can catch the existing errors as well as raise your own exception using try catch syntax of the python

Python gives you the facility to wrap the code around and make a reusable unit. This is known as writing functions in python.

Python functions is a long topic of discussion. This movie will take passing multiple arguments into account. Now you will be able to pass n number of arguments as well as set default values in them

Python has got KWArgs that can handle dictionary like arguments in any order. This is a useful way to tackle the multiple argument, passed in any order.

Python can save a lot of memory. This can be done via generators. If you are not too much concerened about the memory then other way of writing code will work fine to you too.

Python and regular Expression, when these two are combined, this killer duo can be unmatched. Most of the scripting is dependent on regEx and python has got a few modules that can simplify the task.

python, not only can search for a patter anywhere, it can also replace or do further processing on that data. We stringly recommend to read more about re module.

Python being an Object Oriented programming, if we don't talk about classes and objects, that would not be a fair thing to do with python. Let's learn and talk about objects and classes in python.

Python functions when are written and grouped under any class are known as methods. methods also have a default parameter known as self.

Python getters and setters looks like adding pain, in the first look. But they give more control to the application. Everything can be monitored and debugging process becomes easy.

Inheritance is the ability to grab all the properties and methods from a pre written class. Most of the time we just add a few functions and inherit from existing class.

Decorators is a special syntax to write methods using various keywords like @property. This again may look like adding senseless code but gives immense control and gives the ability to look functions just like properties.

Python Standard libraries allow you to import modules and use those functionality straight away. We would recommend to at least take a look on all of them, so that you can have an idea, where to look for what you are looking for.

When Python Standard Libraries fails or are not present to fulfil the task that you want to do, then you might want to look at PyPi. Let's have a look on adding third party libraries

Finally lets tackle the database. Although python is capable of handling most of the database but for simplicity, we will use sqlite3 which is very common now a days and friendly too.

Thanks for watching the course.
