在Python中字典的新增

举例1：

a = {'date': '2022-06-15 14:02:31.345808', 'time': '1655272951346'}
c="aa"
d=2
a.update({c:d})
print(a)
# {'date': '2022-06-15 14:02:31.345808', 'time': '1655272951346', 'aa': 2}

举例2：

a = {'date': '2022-06-15 14:02:31.345808', 'time': '1655272951346'}
a['aa'] = 2
print(a)
# {'date': '2022-06-15 14:02:31.345808', 'time': '1655272951346', 'aa': 2}

举例3：

a = {'time': '1655272951346'}
c=["name","address","phone"]
d=["jack","shenzhen","13214564554"]

# 方式一:
for j,k in zip(c,d):
    a.update({j:k})
print(a)
#{'time': '1655272951346', 'name': 'jack', 'address': 'shenzhen', 'phone': '13214564554'}

举例4：

b = dict(zip(c,d))
print(b)
# {'name': 'jack', 'address': 'shenzhen', 'phone': '13214564554'}
a.update(b)
print(a)
# {'time': '1655272951346', 'name': 'jack', 'address': 'shenzhen', 'phone': '13214564554'}
