Question

python 把一个字典key的值加到另一个字典的key的值中？

字典1: {A:[2136, 1888, 2102, 1911, 1966],B:[123,698,2564]}
字典2: {A:[2136, 1695, 2102, 1888]}
j结果：{A:[2136, 1888, 2102, 1911, 1966,2136, 1695, 2102, 1888],B:[123,698,2564]}

Answer 1

import openpyxl

a = {'A': [2136, 1888, 2102, 1911, 1966], 'B': [123, 698, 2564]}
b = {'A': [2136, 1695, 2102, 1888]}

for key in a.keys():
for bkey in b.keys():
if bkey == key:
for i in b[bkey]:
a[key].append(i)
print(a)

格式如上,注意对齐

Answer 2

A = 'A'
B = 'B'
d1 = {A: [2136, 1888, 2102, 1911, 1966], B: [123, 698, 2564]}
d2 = {A: [2136, 1695, 2102, 1888]}
from collections import defaultdict

d3 = defaultdict(list)
for d in [d1, d2]:
for k in d.keys():
d3[k].extend(d[k])
print(d3)
#defaultdict(<class 'list'>, {'A': [2136, 1888, 2102, 1911, 1966, 2136, 1695, 2102, 1888], 'B': [123, 698, 2564]})
