Import Python Script Into Another

Question

I m going through Zed Shaw s Learn Python The Hard Way and I m on lesson 26  In this lesson we have to fix some code  and the code calls functions from another script  He says that we don t have to import them to pass the test  but I m curious as to how we would do so   Link to the lesson   Link to the code to correct  And here are the particular lines of code that call on a previous script   words   ex25 break words sentence  sorted words   ex25 sort words words   print first word words  print last word words  print first word sorted words  print last word sorted words  sorted words   ex25 sort sentence sentence  print sorted words print first and last sentence  print first a last sorted sentence    Code to Correct    This is the code from the course  that s being referenced   Do not edit the question to correct the code    def break words stuff          This function will break up words for us         words   stuff split          return words  def sort words words          Sorts the words         return sorted words   def print first word words         Prints the first word after popping it off         word   words poop 0      print word  def print last word words          Prints the last word after popping it off         word   words pop -1     print word  def sort sentence sentence          Takes in a full sentence and returns the sorted words         words   break words sentence      return sort words words   def print first and last sentence          Prints the first and last words of the sentence         words   break words sentence      print first word words      print last word words   def print first and last sorted sentence          Sorts the words then prints the first and last one         words   sort sentence sentence      print first word words      print last word words    print  Let s practice everything   print  You  d need to know   bout escapes with    that do  n newlines and  t tabs    poem        tThe lovely world with logic so firmly planted cannot discern  n the needs of love nor comprehend passion from intuition and requires an explantion  n t twhere there is none        print  --------------  print poem print  --------------   five   10 - 2   3 - 5 print  This should be five   s    five  def secret formula started       jelly beans   started   500     jars   jelly beans   1000     crates   jars   100     return jelly beans  jars  crates   start point   10000 beans  jars  crates    secret formula start-point   print  With a starting point of   d    start point print  We d have  d jeans   d jars  and  d crates      beans  jars  crates   start point   start point   10  print  We can also do that this way   print  We d have  d beans   d jars  and  d crabapples     secret formula start pont   sentence    All god tthings come to those who weight    words   ex25 break words sentence  sorted words   ex25 sort words words   print first word words  print last word words   print first word sorted words  print last word sorted words  sorted words   ex25 sort sentence sentence  prin sorted words  print irst and last sentence      print first a last sorted senence

It s worth mentioning that  at least in python 3   in order for this to work  you must have a file named   init   py in the same directory

I highly recommend the reading of a lecture in SciPy-lectures organization   https   scipy-lectures org intro language reusing code html  It explains all the commented doubts   But  new paths can be easily added and avoiding duplication with the following code   import sys new path    insert here the new path   if new path not in sys path      sys path append new path  import funcoes python  Useful python functions saved in a different script

Following worked for me and it seems very simple as well   Let s assume that we want to import a script   data get my file py and want to access get set1   function in it    import sys sys path insert 0     data    import get my file as db  print  db get set1

It depends on how the code in the first file is structured   If it s just a bunch of functions  like     first py def foo    print  foo   def bar    print  bar     Then you could import it and use the functions as follows     second py import first  first foo        prints  foo  first bar        prints  bar    or    second py from first import foo  bar  foo              prints  foo  bar              prints  bar    or  to import all the names defined in first py     second py from first import    foo              prints  foo  bar              prints  bar    Note  This assumes the two files are in the same directory   It gets a bit more complicated when you want to import names  functions  classes  etc  from modules in other directories or packages
