Write a program checkLuminance that will input red, green, and blue values, and compute the luminance using the weighted average (as below). But then print out a warning to the user based on the computed luminance:

• If the luminance is less than10, “That’s going to be awfully dark.”
• If the luminance is between 50 and 200, “Looks like a good range.”
• Over 250, “That’s going to be nearly white!”

```
def checkLuminance(redValue, greenValue, blueValue): luminance = (redValue+greenValue+blueValue)/3
if luminance <10:
print "That's going to be awfully dark."
if (luminance >50) and (luminance<200):
print "Looks like a good range."
if luminance>250:
print "That's going to be nearly white!"
```
