If..else..elif If..else..elif : code if person_age < 4: ticket_price = 0elif person_age < 18: ticket_price = 5elif person_age < 65: ticket_price = 10else: ticket_price = 5 Python does not require an else block at the end of an if-elif chain. Sometimes an else block is useful; sometimes you can avoid using.
Condition symbols or operators Operators evaluation: 1) == Equal to operator - True when matches - False when don't match.CASE == CASE (matches and True in this case)Name = 'Vijay'Name == 'vijay' (False)Age = 18Age == 18 (True) 2) != not equal to operator - True when matches - False when don't match. CASE !=… Continue reading 5 Python Conditional Statements 3 – Condition operators or symbols

Python Conditional Evaluation Programming often involves examining a set of conditions and deciding which action to take based on those conditions. Python’s if statement allows you to examine the current state of a program and respond appropriately to that state. Programming Statements: If...elif...else If..Else statements can be used with:VariablesListsArraysand more....
Pointing to a list Assigning the a variable to a List - Code BOTH VARIABLES POINTING TO THE SAME LIST Any changes made to list appears same in both variables now VAR1 = VAR2 - there is no : used in this case print("Copying list from one to another") my_favorite_foods = ['pizza', 'rice', 'cake'] friends_favorite_foods… Continue reading 4 Python List – Pointing to the same List

Traditional processing VS Real time In traditional relational database management systems, data was often moved to computational space for processing. In Big Data space bringing the computation to where data is located. So, everything is real-time. A key feature of these types of real-time notifications is that they enable real-time actions. However, using such a capability would require you to… Continue reading Traditional DBMS vs Big data
