Import Python Script Into Another?

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 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.
