I'm using Raspberry PI for my robotic project. I got this error when try run this code into my raspberry PI through terminal.

#servo_example.py
import servo
servo.servo_setup()
#0 - 180 degrees only!
servo.servo_set_deg(145)
servo.servo_cleanup()
Error message
Traceback (most recent call last):
  File "servo_example.py", line 2, in <module>
    import servo
ImportError: No module named servo
Why I got this error message? How I can fix it?
                Did you try pip?  You have enough rep on this site that I am surprised that when your program complained that your module didn't exist your first thought wasn't "is this installed?".

You have named your script servo.py. This means that when you import servo, you are importing your own script. It doesn't have a function named servo_setup so you get an error. You can't import the system's servo.py while your own script is named servo.py. Solution: name your script something else.
