获取Python 3中变量的百分比

Question

我似乎无法弄清楚如何获得变量的百分比。这是确切的任务：

  

用Python编写程序，每行存储一个单词列表   一个文本文件，打印并计算长词的数量，即单词   超过10个字符，表示长的百分比   给定文本文件中单词总量的单词。

这是我的代码：

wordcount = 0
longwordcount = 0

for line in sys.stdin:
    line = line.rstrip()
    charnum = len(line)
    wordcount = wordcount + 1
    percentage = int(longwordcount // wordcount) * 100
    if charnum > 10:
         longwordcount = longwordcount + 1
         print(line)



print("There are {0} words in the word list that have more than 10 characters.\nThis is {1}% of the total number of words in the text file." 
.format(longwordcount, percentage))

Answer 1

使用除法运算符代替换层运算符而不是int类型转换。如果需要，您可以使用格式语句来限制位数。

percentage = longwordcount / wordcount * 100
