Just thought of creating an online journal to revise things on the go, cause when I was reviewing video lectures from the beginning it took a lot of time. Sometimes I've to fast forward, normal pace at confusing situations & again fast forward made me sick of revising videos.I'm only considering the Python language and use of its objects in this section.
This is just an index of all the topics upto Mid Term 1: (Still revising Classes is left for me :( )
Lets begin: (All the links lead to quick overview of respective topic and below the Titles I've briefly written about the stuff that topic contains)
- Syntax, Static Semantics, Semantics of a Language
- Deals with types of Knowledge, Computer Program and Aspects of Language
- Compiler-Interpreter, Objects of Python and Type Casting
- Is Python Compiled or Interpreted? Scalar-Non Scalar Objects and int, float operations and comparisons, Type Casting
- Operations on String and Taking input from User
- Declaring, Concatenating, Extracting, Indexing and Slicing. Using raw_input for script to pause and wait for user to input.
- Branching Program: Using if, if-else, if-elif
- Some simple scripts to introduce branching (I don't think we need to go through this, but posted just to maintain flow)
- Iteration or Looping and How to use range()
- A simple code explaining iteration, !Imp: How range() works. When to use while and when for.
- Guess and Check method
- Two small codes for finding square root of a perfect square and imperfect square. Use of abs() done in between.
- Linear Search v/s Binary (Bisection) Search
- Efficiency of Linear and Bisection search discussed along with algorithm and scripts of really simple example.
- Finding nth root
- This one is included to resurrect forgotten ;-) programming skills that we learned in video lectures. Worth going through, it won't take much time though.
- Recursion - How it works?
- First coded an example in Iterative manner, then recursively, and then explained the recursive environment changes by using different colors.
- Python Object - Tuples
- Declaration, Singleton Tuple, Nested Tuple, Concatenation, Indexing and Slicing in Tuples
- Python Object - Lists and its Mutation
- Imp! Difference between Assigning a list and Copying a list (a self made image in the end explains it perfectly) and How List is different from String and Tuple
- Complexity or Order of Growth in Programming
- Till now O(1) , O(n), O(log n) and O(n log n) are discussed with simplest of the examples and images.
