Python lists nest the sort of fields under multiple dictionaries

First, you need to install the package through the PIP Install operator, itemGetter can sort multiple fields with type int. The code snippet is as follows:

from operator import itemgetter

d = [
    {"name": '李一'.'chinese': 66, 'mathematics': 98},
    {'name': 'the king 2'.'chinese': 99, 'mathematics': 68},
    {'name': 'Joe'.'chinese': 88, 'mathematics': 78},
    {'name': 'Liu Si'.'chinese': 88, 'mathematics': 99}]Sort sorted by sorted:
s = sorted(d, key=lambda x: x['chinese'], reverse=True)

Sort by using the sorted method +itemgetter
ss = sorted(d, key=itemgetter('chinese'.'mathematics'), reverse=True)

Sort by sort
d.sort(key=lambda x: x['chinese'], reverse=True)
Copy to SS by slice
sss = d[:]  

print(s)
print(ss)
print(sss)
Copy the code
