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)
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

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

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)
This question is related to
python
python-2.7
import
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'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
Hope this work
