After i run Python i recive this message: Python 2.7.9 (default, Dec 10 2014, 12:24:55) [MSC v.1500 32 bit (Intel)] on win32 Type 'copyright', 'credits' or 'license()' for more information. Whenever I try to run module, it keeps showing 'Invalid Syntax' and highlighted ArduinoSerial of print ArduinoSerial.readline(). For Arduino it is working fine and able to read 1 & 0.

From the PC side, instead, you will activate a serial session in a Python shell (but it can be replaced by any program in Python) that will read the contents of the file (CSV or TXT) by sending appropriate signals via serial to the Arduino.

So I tried to execute single line in shell. Then I found that there is no Attribute named Serial in module serial. And I get this error.

When using readline with Python Serial the states Be carefully when using readline(). Do specify a timeout when opening the serial port otherwise it could block forever if no newline character is received.

Also note that readlines() only works with a timeout. Readlines() depends on having a timeout and interprets that as EOF (end of file). Camp cope a lot program outline. It raises an exception if the port is not opened correctly. This is what you are seeing so in your python code when you open the port arduino8 = serial.Serial(port, baudrate=brate, timeout=None) you should probably set the timeout to a reasonable value, like 1 second or more depending on your use, so that the library gives up waiting after a while.
