10. Analysis of algorithms: l .A Priori estimates 2. A Posteriori testing
11. Complexity of an Algorithm : 1. Time Complexity 2. Space Complexity
12. Two main factors : I.Time 2.Space
13. Exponent data: digit part, decimal point, exponent part
14. Number Data type: integers, floating point numbers and complex numbers.
15. Python Data types: Number, String, Boolean, tuples, lists and dictionaries
16. Control structures : Sequential, Alternative or Branching, Iterative or Looping
17. Alternative or Branchin2 Statement: I.Simple if statement 2.if..else 3. if..elif
18. Looping constructs: while loop ,for loop
19. Types of Functions: User-defined, Built-in, Lambda, Recursion Functions
20. Function Ar2uments: Required, Keyword, Default, Variable-length.
21. Variable Len2th ar2uments: 1. Non keyword 2. Keyword variable
22. Use of lambda or anonymous function : filter(), map(), reduce()
23. Scope of Variables: local scope and global scope.
24. Advantages of DBMS: 1. Segregation of application program 2.Minimal data duplication or Data Redundancy 3.Easy retrieval of data using the Query Language 4.Reduced development time and maintenance
25. Object Model Example : Shape, Circle, Rectangle ,Triangle.
26. Relational Algebra is divided into various groups:
    Unary Relational Operations: I.SELECT ( symbol: 0) 2.PROJECT ( symbol: II) Relational Algebra Operations from Set Theory: I.UNION (u) 2.INTERSECTION (n) 3.DIFFERENCE (-) 4.CARTESIAN PRODUCT (X)
27. Processing Skills of SQL:
    1. Data Definition Language (DDL), 2. Data Manipulation Language (DML)
    3. Embedded Data Manipulation Language 4. View Definition 5. Authorization 6. Integrity
28. DQL COMMAND- SELECT command:

29. Writing different Data formats Into like Different l.auotes (” Types “), in 2.pipe Csv (I) Files: 3.comma (,).
    I .Creating A New Normal CSV File 2.Modifying An Existing File 3.Writing On A CSV File with Quotes 4.Writing On A CSV File with Custom Delimiters 5.Writing On A CSV File with Line terminator 6.Writing On A CSV File with Quote chars Writing CSV File Into A
30. Applications of Scripting Languages:V
    1. To automate certain tasks in a program 2. Extracting information from a data set 3. Less code intensive as compared to traditional programming language
