频率分布Python。。。最后一期

当我尝试打印FreqDist对象时，在打印结束时会得到“…”？ 我试着在网上找，但找不到

请告诉我哪里出了问题

代码：

for word in nltk.word_tokenize(lin):
    fdist.inc(word)

print fdist

---

使用

fdist

时，它返回键值对列表。你必须用循环打印出来。下面这样的方法应该可以工作：

import nltk
from nltk.tokenize import word_tokenize

lin = "A frequency distribution for the outcomes of an experiment. A frequency distribution records the number of times each outcome of an experiment has occurred. For example, a frequency distribution could be used to record the frequency of each word type in a document. Formally, a frequency distribution can be defined as a function mapping from each sample to the number of times that sample occurred as an outcome."

fdist = nltk.FreqDist()

for word in word_tokenize(lin):
    fdist.inc(word)

for f in fdist:
    print f, fdist[f]

结果是：

frequency 5
of 5
a 4
distribution 4
the 4
an 3
each 3
, 2
A 2
as 2
be 2
number 2

让我们知道这是否有帮助

另一种方法：

import nltk
from nltk.tokenize import word_tokenize

lin = "A frequency distribution for the outcomes of an experiment. A frequency distribution records the number of times each outcome of an experiment has occurred. For example, a frequency distribution could be used to record the frequency of each word type in a document. Formally, a frequency distribution can be defined as a function mapping from each sample to the number of times that sample occurred as an outcome."

tokens = word_tokenize(lin)
fdist = nltk.FreqDist(tokens)

for f in fdist:
    print f, fdist[f]

---

输出是相同的。
