Yes, just say "from file import function".  Or else prefix the function
name with the module name.

For example, you can start up Python and type:

  import math
  print math.sqrt(25)   # should print 5
  print sqrt(25)        # throws an exception since sqrt is not in namespace

Alternatively, you can type:

  from math import sqrt
  print sqrt(25)        # this will work now
