Python Crash Course : Part 2


For learning core of any programming language it is necessary to learn three fundamental types of language constructs :
1.       Sequential Statements
2.       Control Statements
3.       Iterative Statements
It is just that simple , only three things to learn .Cool !!

Sequential Statements in Python

·         Variables(memory) are integral part of any algorithm implementation.
·         There is no need of declaring data type of the variable used, Python implies the data type based on context. Which is similar in Scripting language like JavaScript[here we use 'var' keyword].
Example : x=1 , x=’string’ , x=0.000 . Based on type of data at RHS the datatype of variable is implied.

·         INPUT and OUTPUT constructs in Python  :

INPUT :

                                Example : y=input(“Please , Provide the value of Y”)
 input() function provides the basic system input which can be responded by user keyboard.
 As said earlier the data type of variable Y will be implied based on the input given by the user.

        OUTPUT:

                                Example : print(y)
print() function provides the basic system output onto console.
·         Few other categories in Python sequential constructs are Operators , which are similar to other programming languages.


·         Coding using learnt constructs :                
x=’Hello World’
y=input(“Please Enter your name”)

print(“This is”+x” “+”Program written by :”+y)

Create One-Click Shutdown and Reboot Shortcuts

First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC. But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this: shutdown -r -t 01 -c "Rebooting your PC" Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use. I use this technique to create two shutdown shortcuts on my desktop—one for turning off my PC, and one for rebooting. Here are the ones I use: shutdown -s -t 03 -c "Bye Bye m8!" shutdown -r -t 03 -c ...

Event Sourcing with CQRS.

  The way event sourcing works with CQRS is to have  part of the application that models updates as writes to an event log or Kafka topic . This is paired with an event handler that subscribes to the Kafka topic, transforms the event (as required) and writes the materialized view to a read store.
