在python中循环替换函数以获得不同的随机输出

嘿，伙计们，如果我不能很好地表达我的问题，我会提前道歉，但我现在需要帮助

基本上，我想浏览文本列表，并用随机选择的单词替换某些元素。我可以从列表中随机抽取单词，但是一旦我把它们分配到一个特定的单词，它们都是一样的

也就是说，我想改变这一点：

DT JJ NNP  DT JJ NN I PRP VBD JJ NN IN DT JJ NN CC VBD VBN IN RB CD 8 CD JJ
NN IN I PRP VBP IN PRP JJ NN  PRP VBP RP DT JJ NN CC I PRP VBD VBG RB RB  VB
DT NN VBD VBG RB
IN DT JJ NN CC PRP VBD VBN IN NN CC WP I PRP VBP TO VB NN

为此：

  DT JJ NNP  DT JJ shopping I PRP VBD JJ bag IN DT JJ house CC VBD VBN IN RB CD 8 CD JJ fun 
 IN I PRP VBP IN PRP JJ hatred  PRP VBP RP DT JJ bum CC I PRP VBD VBG RB RB CC VB DT 

到目前为止，我的代码是：

import random, re

def get_noun():
    infile = open('nouns.txt', 'r') #opens the file, preps it to be read
    nouns = infile.readlines() # reads each line of the file
    infile.close() # closes the file


    index = 0 # starts at the begining of the list

    while index < len(nouns): # first part of the counter
        nouns[index] = nouns[index].rstrip('\n') # i believe this goes through and strips each line of the /n thing, which is usually output at the end of each line
        index += 1 # counts up until it hits the final length number of the list
    noun = random.choice(nouns) # outputs a random line from the list.
    return noun

print (get_noun() + get_noun())



def work_plz():
    fun = open('struc1.txt', 'r')
    readS = fun.readlines()
    fun.close

    index = 0

    while index < len(readS): # first part of the counter
        readS[index] = readS[index].rstrip('\n') # i believe this goes through and strips each line of the /n thing, which is usually output at the end of each line
        index += 1
    okay = [w.replace('NN', get_noun()) for w in readS]
    return okay

print (work_plz() + work_plz())

在程序中，我想用get_noon（）函数中的不同单词替换所有NN，但它似乎只将一个单词拉入缓冲区，并将其用于所有单词

有人知道我哪里出错了吗？我怀疑这与：

 okay = [w.replace('NN', get_noun()) for w in readS]

但我不知道如何重新循环它，以便为每个“NN”生成不同的结果

如果你能帮我，我真的会很高兴的

干杯

编辑：

以下是我从thanasissdr复制的代码：

 import random

nouns = 'file/path/nouns.txt'
infile = file/path/struc1.txt'

def get_noun(file):
''' This function takes as input the filepath of the file where the words you want to replace with are stored and it returns
a random word of this list. We assume that each word is stored in a new line.'''
def random_choice(lista):
    return random.choice(lista)
with open(file, 'r') as f:
    data  = f.readlines()
    return random.choice(data).rstrip()


with open(infile, 'r') as f:

big = [] ## We are going to store in this list all the words in the "infile" file.
data = f.readlines() ## Read the file.
for row in data:
    c = row.rstrip() ## Remove all the '\n' characters.'
    d = ','.join(c.split())  ## Separate all the words with comma.
    d = d.split(',') ## Storing all the words as separate strings in a list.

    ## This is the part where we replace the words that meet our criteria.
    for j in range(len(d)):
        if d[j]== 'NN':
            d[j] = get_noun(nouns)
    big.extend(d) ## join all the rows (lists) in a big list.
print (' '.join(big)) ## returns the desired output.

它还活着。非常感谢你们的帮助。我让这一个工作，和脚本的孩子，我是我要保持这样的哈哈哈。我会尽我最大的努力去理解你们展示给我的一切，但我很满足于让它这样运行。我希望这不是不礼貌的礼节！所有的传说

我不知道你是否了解字典，但鉴于你似乎在使用nltk或类似的东西，我假设你知道。这里有一个版本维护一个名为

Words[code]

的字典，其中的代码类似于“NN”。每个条目都是一个单词列表，因此您可以随机选择一个

您可以读取多个文件，每个代码，等等。我正在使用一些虚拟数据编写文件-您可能应该在尝试使用它之前删除这些文件

import random

with open('nouns.txt', 'w') as outfile:
    contents = """
fox dog
shopping bag # Not sure this is right. Shopping?
fun house
hatred # Or this
bum
"""
    print(contents, file=outfile)

with open('struc1.txt', 'w') as outfile:
    contents = """
DT JJ NNP  DT JJ NN I PRP VBD JJ NN IN DT JJ NN CC VBD VBN IN RB CD 8 CD JJ
NN IN I PRP VBP IN PRP JJ NN  PRP VBP RP DT JJ NN CC I PRP VBD VBG RB RB  VB
DT NN VBD VBG RB
IN DT JJ NN CC PRP VBD VBN IN NN CC WP I PRP VBP TO VB NN
"""
    print(contents, file=outfile)

Words = dict()

def get_words(path, code):

    words = Words[code] = []

    with open(path, 'r') as infile:
        for line in infile:
            words.extend(line.split('#', 1)[0].strip().split())

def random_word(code):
    wordlist = Words.get(code)
    if wordlist is None:
        return code

    return random.choice(wordlist)


def work_plz(path):
    with open(path, 'r') as infile:
        for line in infile:
            line_out = []
            for token in line.strip().split():
                line_out.append(random_word(token))

            print(' '.join(line_out))

get_words('nouns.txt', 'NN')
work_plz('struc1.txt')

如果您感兴趣，我已经创建了一个代码，它完全符合您的要求（

python3

）

哇！非常感谢。不幸的是，我认为我运行的是最新版本的Python，而不是2.7。不管怎样，我在编译代码时出错了。回溯（最后一次调用）：文件“novgentest2.py”，第16行，在中以open（infle，'r'）作为f:TypeError：强制使用Unicode：需要字符串或缓冲区，文件foundHrmmmm我仍然收到相同的错误。我将编辑我的主要帖子，向您展示我是如何设计代码的。你能告诉我哪里出错了吗？再次感谢你的帮助！！！我想这是因为我试图打开文件两次！嘿，伙计，我在用nltk，但我不知道字典。正如您可能知道的，我昨天才开始使用lib，现在仍在努力学习python。非常感谢你帮我把这个打印出来！
