Python path is the location where Python looks for modules and packages to import.

• Python path is a list of directories that Python searches for modules when importing them.

• It can be set using the PYTHONPATH environment variable.

• Python path can also include the current working directory.

• Example: PYTHONPATH=/usr/local/lib/python3.8

• Example: import sys; print(sys.path)

Python 2 and Python 3 are two different versions of the Python programming language with various differences.

• Python 2 is legacy, Python 3 is the present and future

• Print statement: Python 2 uses print as a statement, Python 3 uses print() as a function

• Division: Python 2 performs integer division by default, Python 3 performs float division

• Unicode support: Python 3 supports Unicode by default, Python 2 requires specifyin...read more

Microcontroller selection depends on project requirements, such as processing power, memory, peripherals, and cost. i2c is a serial communication protocol for connecting multiple devices, while SPI is a faster protocol for high-speed communication.

• Consider project requirements like processing power, memory, peripherals, and cost when selecting a microcontroller.

• i2c is a slower serial communication protocol commonly use...read more

Selecting a microcontroller involves considering factors like processing power, memory, peripherals, cost, and compatibility with the project requirements.
