Python Serial Library Commands
I am writing a Python v3.6.0 program on a Windows PC that takes an input from the Serial port and then parses the input, and replies on the Serial port based on the input.
I tied COM1 and COM2 together. My Python script running is connected to COM1 and the Arduino serial monitor connected to COM2. I am using the pySerial library's command '.readline()' to send the serial communication bytes to my Python script.
According to the pySerial docs. the .readline() command will return a string after it receives a 'n' character. However, when I send a string of text through the Arduino serial port monitor without a newline character at the end of it, the .readline() method returns that string. If I do send a string with a newline character, the newline character does get sent with the string to the rest of my script from the .readline() method.
Does anyone know why how the .readline() method knows to return the 'line' even though there is no newline character at the end of it?

Thanks,

The Python Standard Library ¶. The library contains built-in modules (written in C) that provide access to system functionality such as file I/O that would otherwise be inaccessible to Python programmers, as well as modules written in Python that provide standardized solutions for many problems that occur in everyday programming. Python Control LED with Serial Communication RS232. You need to configure the environment variables to be able to properly execute Python commands from a Windows Shell (Command Prompt). First thing we need to do is importing the Serial library so that Python has the ability to communicate with the available serial ports. It's just like.
