字典排序，初始化，簡單使用

如

想對字典wordhash排序：

通過list實現：wordlist

wordhash=

wordlist = [('\ufeff', 1), ('calvin', 1), ('shi', 1), ('鏈結', 1), ('www', 1), ('zhihu', 1), ('question', 1), ('27068465', 1)]

item:item[1]代表是元組('calvin', 1)中的第二個元素『1』進行排序

reverse=false代表詞頻從小到大

wordhash = {} 　　#字典的初始化

wordhash = cipin(content)
wordlist = sorted(wordhash.items(),key=lambda item:item[1],reverse=false) 
for tuple in wordlist:
word = tuple[0]
print(word+' '+str(wordhash[word]))

def cipin(content):

wordhash = {}
words = content.split()
for word in words:
if word in wordhash:
wordhash[word] += 1
else:
wordhash[word] = 1
return wordhash
