[英]all unique permutations of the tokens
Output all unique permutations of the tokens from part 1. And the total number of permutations. Output 第 1 部分中标记的所有唯一排列。以及排列总数。
Example:例子:
do you know how to do it in python?你知道python怎么做吗?
import itertools
import itertools
from nltk.tokenize import word_tokenize
import nltk
nltk.download('punkt')
def tokenize_word():
sentence = str(input("please right a comment: "))
punctuation = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
# Removing punctuations in string
# Using loop + punctuation string
for element in sentence:
if element in punctuation:
sentence = sentence.replace(element, "")
tokenize_sentence= word_tokenize(sentence)
alphabetics_order_sentence = sorted(tokenize_sentence)
for i in range(1, len(alphabetics_order_sentence) + 1):
permutations= itertools.permutations(alphabetics_order_sentence)
print(permutations)
tokenize_word()
You can use the function permutations
from the package itertools
(if package is allowed).您可以使用 package
itertools
中的 function permutations
(如果允许 package)。
from itertools import permutations
st = "This is a test"
result = list(permutations(st.split()))
for i in result:
print(" ".join(i))
print()
print("The number of permutations is {}".format(len(result)))
Output from code above: Output 来自上面的代码:
This is a test
This is test a
This a is test
This a test is
This test is a
This test a is
is This a test
is This test a
is a This test
is a test This
is test This a
is test a This
a This is test
a This test is
a is This test
a is test This
a test This is
a test is This
test This is a
test This a is
test is This a
test is a This
test a This is
test a is This
The number of permutations is 24
