我有一个在其中创建的列表function1。我希望能够访问和修改它function2。如果没有全局变量，我该如何做到这一点？
这两个函数都不嵌套在另一个函数中，我需要能够将其推广到多个函数中的多个列表。
我希望能够访问word_list and sentence_starter在其他功能中。
def Markov_begin(text):
print create_word_lists(text)
print pick_starting_point(word_list)
return starting_list
def create_word_lists(filename):
prefix_dict = {}
word_list = []
sub_list = []
word = ''
fin = open(filename)
for line in fin:
the_line = line.strip()
for i in line:
if i not in punctuation:
word+=(i)
if i in punctuation:
sub_list.append(word)
word_list.append(sub_list)
sub_list = []
word = ''
sub_list.append(word)
word_list.append(sub_list)
print 1
return word_list
def pick_starting_point(word_list):
sentence_starter = ['.','!','?']
starting_list = []
n = 0
for n in range(len(word_list)-1):
for i in word_list[n]:
for a in i:
if a in sentence_starter:
starting_list += word_list[n+1]
print 2
return starting_list
def create_prefix_dict(word_list,prefix_length):
while prefix > 0:
n = 0
while n < (len(word_list)-prefix):
key = str(''.join(word_list[n]))
if key in prefix_dict:
prefix_dict[key] += word_list[n+prefix]
else:
prefix_dict[key] = word_list[n+prefix]
n+=1
key = ''
prefix -=1
print Markov_begin('Reacher.txt')
您应该将其重构为一个类：
class MyWords(object):
def __init__(self):
self.word_list = ... #code to create word list
def pick_starting_point(self):
# do something with self.word_list
return ...
Usage
words = MyWords()
words.pick_starting_point()
...
