Question

PUMC = ".,?!()[]:;"
def readIntoSet(filename):
wordSet = set()
inputFile = open(filename,"r")
for line in inputFile:
line = line.strip()
parts = line.strip()
for word in parts:
word = word.strip()
word = word.strip(PUMC)
if len(word) > 0:
wordSet.add(word.lower())
inputFile.close()
return wordSet

这段是什么作用

Answer 1

从文本文件统计剔除".,?!()[]:;"后的词句。
你这代码，引用得用代码块贴进来，不然没有缩进代码会不好判断
