result = list(enumerate(ha))

for i in result[3::9]:
if ha[i[0]] == '0' and ha[i[0] + 1] == '0':

@weyou 大神好厉害，牛 B 。

line = " 以及： "
pattern = re.compile('\((\S+)\)')
result = pattern.findall(line)
print(result)

import os
import re

domain_dict = {}
with open('mail.txt', encoding='utf-8') as f:
for line in f:
domain = re.split('@|:', line)[1]
domain_dict.setdefault(domain,[]).append(line)
for v in domain_dict.values():
print(v[0])

写的挺丑的，有更好的，我再回来贴上。

mylist= {"key1": [{'a': '1'}, {'b': '2'}], "key2": [{"a": 2}, {"c": 4}]}

result = {}
for key, val in mylist.items():
for i in val:
result.setdefault(list(i)[0],[]).append(key)
print(result)

def in_alphabet(char):
char = str(char)
if char.islower():
return 'LowerCase'
elif char.isupper():
return 'UpperCase'
else:
return 'NotInAlphabet'

print(in_alphabet('a'))
print(in_alphabet('A'))
print(in_alphabet(1))

写的很粗糙，目前的理解就写样了。请多多指教。

from datetime import datetime

time_list = []
now = datetime.now()
start_day_hour = int(now.strftime('%Y%m%d00'))
stop_day_hour = int(now.strftime('%Y%m%d%H'))
for i in range(start_day_hour, stop_day_hour + 1):
time_list.append(i)

print(time_list)

@weyou 大神，没看懂，请指点指点。

dict_list = [{'姓名':'张三','体重':76,'UpdateTime':'xxx'}, {'姓名':'张三','体重':76,'UpdateTime':'xxx'}, {'姓名':'张三','体重':76,'UpdateTime':'xxx'}, {'姓名':'张三','体重':76,'UpdateTime':'xxx'}]

list_dict = {}

for i in dict_list:
list_dict.setdefault((i['姓名'], i['体重']), []).append('')

print(list_dict)

@xiaolinjia 装您的代码抄了一下。请问代码是怎么传到 ubuntu 上的？

list = [{'a': 1},{'a':2},{'a':3}]

for index, mem in enumerate(list):
if index < len(list) - 1:
print(mem['a'])
print(list[index + 1]['a'])

mylist= {"key": [{'a': '1'}, {'b': '2'}]}

all = {}

for k, v in mylist.items():
for j in v:
all.setdefault(k, []).append(list(j.keys())[0])

print(all)

tabledata = {
"A0801_000000_201301": "1,321.8",
"A0801_000000_201302": "1,199.8",
"A0801_000000_201309": "1,433.4",
"A0802_000000_201305": "6,688.3",
"A0802_000000_201306": "8,085.2",
"A0802_000000_201307": "9,481.0",
"A0802_000000_201308": "10,878.4",
"A0802_000000_201309": "12,311.8",
"A0802_000000_201310": "13,739.9",
}

output = {}
for k, v in tabledata.items():
(a, b, c) = k.split('_')
output.setdefault(a,[]).append({c: v})
print(output)
