import user_defined_file

will do it (once) assuming the file is named user_defined_file.py and is in
the python path, e. g. in the current directory. However, it is better to
wrap the code in user_defined_file.py into a function to make exceution
independent from import:

import user_defined_file
# more code
user_defined_file.myfunc() 

Please read Python's excellent tutorial - it's a good starting point and has
some info on how to organize your code, too.
