导入功能失败,但是导入功能测试有效

如何解决导入功能失败,但是导入功能测试有效

我使用myfuncs导入函数,但失败了,我确实测试了相同的文件路径,只是文件名稍有不同,但失败了。 python代码已有5年历史了,不确定是否有所更改。

我确实进入了该线程,并且进行了测试,并且在测试中它确实可以成功运行,并且我的实际外观是相同的。

function is not defined error in Python

#!/usr/bin/python

# Our function is pulled in here
from myfunction import pyth_test

pyth_test(1,2)

此测试有效,但是我的实际功能文件不是两个文件都在同一目录中,两个导入都是从import *相同的格式开始的,只是文件名略有不同而已。

测试是否可以导入

from myfunction import *

pyth_test(1,2)

方法成功

however when I try the actual impor of the function I need to use I get this error
---------------------------------------------------------------------------

      9 keywords = myfuncs.get_keywords(titles_lines,bag_of_words)

NameError: name 'myfuncs' is not defined

代码下面是我运行的从名为myfuncs.py的文件调用函数

run.py

from myfuncs import *

f = open('s2-titles.txt',encoding="utf8")
titles_lines = f.readlines()
f.close()

bag_of_words = myfuncs.get_bag_of_words(titles_lines)
keywords = myfuncs.get_keywords(titles_lines,bag_of_words)

myfuncs.py

#!/usr/bin/env python
# coding: utf-8

def get_bag_of_words(titles_lines):

    # bag of words
    bag_of_words = {}
    # [1: ]skips the first line which is the header
    for line in titles_lines[1:]:
        courseid,course_bag_of_words = get_course_bag_of_words(line)
        for word in course_bag_of_words:
                if word not in course_bag_of_words:
                    bag_of_words[word] = course_bag_of_words[word]
                else:
                    bag_of_words[word] += course_bag_of_words[word]
    return bag_of_words

def get_course_bag_of_words(line):
        course_bag_of_words = {}
        #split by weirdcombo to prevent weird splits
        courseid,title,description =  line.split('XXXYYYZZZ')
        title = title.lower()
        description = description.lower()
        wordlist = title.split() + description.split()
        if len(wordlist) >=10:
             for word in wordlist:
                if word not in course_bag_of_words:
                    course_bag_of_words[word] = 1
                else:
                    course_bag_of_words[word] += 1

        return courseid,course_bag_of_words

def get_sorted_results(d):
    kv_list = d.items()
    vk_list = []
    for kv in kv_list:
        k,v = kv
        vk = v,k
        vk_list.append(vk)
    vk_list.sort()
    vk_list.reverse()
    k_list = []
    for vk in vk_list[:10]:
        v,k = vk
        k_list.append(k)
    return k_list

def get_keywords(titles_lines,bag_of_words):
    n = sum(bag_of_words.values())
    keywords = {}
    for line in titles_lines[1:]:
        courseid,course_bag_of_words = get_course_bag_of_words(line)
        term_importance = {}
        for word in course_bag_of_words:
            tf_course =(float(course_bag_of_words[word])/
                         sum(course_bag_of_words.values())
                         )
            tf_overall = float(bag_of_words[word]) /n
            term_importance[word] = tf_course/tf_overall
        keywords[courseid] = get_sorted_results(term_importance)
        if courseid == '74953':
            for word in keywords[courseid]:
                print('has importance',term_importance['word'])
    return keywords

解决方法

我能够弄清楚。看来我不再需要myfuncts.myfuction()来加载just .myfuction()

我更改了此

from myfuncs import *

f = open('s2-titles.txt',encoding="utf8")
titles_lines = f.readlines()
f.close()

bag_of_words = myfuncs.get_bag_of_words(titles_lines)
keywords = myfuncs.get_keywords(titles_lines,bag_of_words)

对此有效并且有效引发了另一个错误,但这完全是另外一回事了。让我搜索SO以找出答案。

from myfuncs import *

f = open('s2-titles.txt',encoding = "utf8")
titles_lines = f.readlines()
f.close()

bag_of_words = get_bag_of_words(titles_lines)
keywords = get_keywords(titles_lines,bag_of_words)
