Program is a recipe
- It has a fixed set of primitives, using them we can program anything- There are six primitives to make a better program
- But we will discuss afterwards
- To describe the recipe, we want a language.
- There is no best language
- And we are going to study Python.
High vs Low
- High language is the language which can be read and code by programmer.
- Low language is the language which contains a high complexity codes which can be understand by machine easily.
General vs Targeted
- General Language is a language which can be used for general-purpose like for making a calculator. Eg : C
- Targeted Language is a language which is used only for specific topic such as MATLAB which is used for solving matrices and graphs.
Interpreted VS Compiled
- Interpreted language is operating directly on the runtime.
- Compiled Language is much faster in execution than the interpreter.
Let's talk about Python :
- Firstly, Python is a high-level language
- Its a general purpose language
- And its interpreted.
- Syntax basically says what are the legal expressions.
- Semantics - what does the program means ? What's gonna happen
- Style - You must write in a way which will lead to better programming
Basics of Python
- int, float and strings = values
- Arithmetic Operators = +-*/
