I am a novice python programmer and would love if someone could please help me. 
I am working in python. I have imported a .shp file that contains a heap of data about buildings. I want to extract the data 'RELHMAX' which is the building height maximums - how can I do this ?

this is the data file. <https://drive.google.com/file/d/0BySL_YFrwgAuTTAzeVlacFdFXzA/view?usp=sharing>

so far i am thinking that I should be able to use the specific RELHMAX data set by

```
buildingHeight = file[RELHMAX]
print buildingHeight

```

thank you so much in advance!!
