AI Agents - Python Basics
Why do we need to use Python to create AI agents?
Because the number of users in the community is bigger, and the number of libraries is more compared to other languages.
Why not use popular languages like Java or Go? Because every language is used for different purposes.
Python is called an interpreted language, which means it executes the code line by line and does not compile it first. Other languages like Java and C++ compile the code (i.e., convert it into binaries, 0s and 1s) and execute it from the compiled file.
Print Function
Prints the content in the console that is inside the function.
A function is simply a plan to do a task repeatedly. Here, we create a function when we do not want to repeatedly do the same work again and again.
Syntax:
def function_name(parameter_list): return
E.g.
print("Hello World") print - is the function_name, and "Hello World" is printed in the console.
print("Hello World", "Hi") Identifier
name = "some name"
The value will be stored in RAM.
There are two types of memory in a computer.
RAM - Random Access Memory - Temporary memory used to access data faster for computational purposes.
ROM - Read Only Memory - Hard drive. Initially, the OS will be stored in the ROM or hard drive. The OS will not run directly from the ROM. When the computer starts, the OS files will be moved to RAM because fetching data from RAM will be much faster. Since RAM is costly, we cannot store all the data in it.
"some name" will be stored somewhere in RAM. We cannot remember the memory address for the process all the time, so we assign a label called "name". In Python, there is no concept called a "Variable". The same label can be replaced with a different memory address. So, the "name" identifier will point to the address where the value is stored.
E.g.
age = 30
Flag = True
name = "Peter"
These are string/boolean/integer/None types of values that can be stored in the identifier.
In Python, everything will be treated as an object. Each object has attributes and functions. Each object may or may not have attributes and functions. To know whether a particular object has attributes and functions, use the method called 'dir'.
dir(age) It will list down the attributes and functions associated with the object.
A special thanks to my mentor Syed Jafer for the continuous guidance and support throughout these sessions. I truly appreciate the effort taken to explain each concept clearly and make the learning process easier.
