There's no global variable content, that was local to the function.  So 
it's lost when the function exits.  it does return the value, but you 
give it to print, and don't save it anywhere.

data = getPDFContent(r"C:\Components-of-Dot-NET.pdf").encode("ascii",
"ignore")

outfile = open('x.txt', 'w')
outfile.write(data)

close(outfile)

I used a different name to emphasize that this is *not* the same 
variable as content inside the function.  In this case, it happens to 
have the same value.  And if you used the same name, you could be 
confused about which is which.
