尝试计算for循环中的单词数时出现问题

问题描述

试图计算for循环中的单词总数，但是sum（）方法不起作用，并且尝试使用list-append方法失败：

for line in open("jane_eyre.txt"):
  strip = line.rstrip()
  words = strip.split()
  for i in words:
    length = len(i)
    if length > 10 and "e" not in i:
      print(i)
      #Can't find a way to make it work here..
      sum(i) 

单词的输出是：

possibility
drawingroom
disposition
drawingroom
introductory
accumulation
introductory
surrounding
continually
inflictions

*无法找到使“ 10”作为总和的方法。

谢谢。

解决方法

sum()不是您要在这里查找的内容。为了更好地了解sum()的用法，请阅读documentation。

您可以在循环之前存储wordcount，并在每次与if语句匹配时增加其值。

words = ['hello','these','are','words','they','get','longer','indtroductory']
wordcount = 0

for word in words:
    if len(word) > 10 and "e" not in word:
        print(word)
        wordcount += 1

#indtroductory
print(wordcount)
#1

如果以后需要访问这些单词，可以将它们附加到列表中，并对列表中存在的对象进行计数，以获取计数。

您可以使用此...

c = 0 #number of words
for line in open("jane_eyre.txt"):
  strip = line.rstrip()
  words = strip.split()
  for i in words:
    length = len(i)
    if length > 10 and "e" not in i:
        print(i)
        #Can't find a way to make it work here..
        c +=1 #increasing number of words
print(c)

,

在这里尝试：

count = 0
for line in open("jane_eyre.txt"):
  strip = line.rstrip()

  words = strip.split()

  for i in words:
    length = len(i)
    if length > 10 and "e" not in i:
        print(i)
        #Can't find a way to make it work here..
        count = count + 1
print(count)
