【Python】对字典进行排序

1 对键排序

（1）方法一 遍历tutle

d = {1:'我',2:'是',3:'帅',4:'哥'}
# reverse = True:从大到小排序
# reverse = Fale：从小到大排序
tt = sorted(d.items(),key = lambda kv:kv[0],reverse = True)
for t in tt:
	print('{}:{}'.format(t[0],t[1]))

4:哥 3:帅 2:是 1:我

（2）方法二 遍历List

d = {1:'我',2:'是',3:'帅',4:'哥'}
# reverse = True:从大到小排序
# reverse = Fale：从小到大排序
tlist = list(d.items())
tlist.sort(key = lambda x:x[0],reverse = True)
for i in range(len(tlist)):
   a,b = tlist[i]
   print('{}:{}'.format(a,b))

4:哥 3:帅 2:是 1:我

2 对值排序

（1）方法一 遍历tutle

d = {'我':1,'是':2,'帅':10,'哥':9}
# reverse = True:从大到小排序
# reverse = Fale：从小到大排序
tt = sorted(d.items(),key = lambda kv:kv[1],reverse = True)
for t in tt:
	print('{}:{}'.format(t[0],t[1]))

帅:10 哥:9 是:2 我:1

（2）方法二 遍历List

d = {'我':1,'是':2,'帅':10,'哥':9}
# reverse = True:从大到小排序
# reverse = Fale：从小到大排序
tlist = list(d.items())
tlist.sort(key = lambda x:x[1],reverse = True)
for i in range(len(tlist)):
   a,b = tlist[i]
   print('{}:{}'.format(a,b))

帅:10 哥:9 是:2 我:1
