分享几种python变量合并方法

a =[91,95,97,99]
b =[92,93,96,98]
c = a+b  # 合并
c.sort()  # 排序  正序
print(c)
c.sort(reverse=True)  # 排序  倒序
print(c)

a =[91,95,97,99]
b =[92,93,96,98]
a[0:0] = b # 合并
a.sort()
print(a)

a =[91,95,97,99]
b =[92,93,96,98]
a += b # 合并
a.sort()
print(a)

a =[91,95,97,99]
b =[92,93,96,98]
a.extend(b) # 合并
a.sort()
print(a)

a =[91,95,97,99]
b =[92,93,96,98]
a.append(b)  # 合并
print(a)

a = '你叫：'
b = '小明'
print(a+b)

a = '你叫：'
b = '小明'
print("%s%s" % (a, b))

y = {'a': 10, 'b': 8}
t = {'d': 6, 'c': 4}
#  把t和并到y里面
y.update(t)
print(y)

y = {'a': 10, 'b': 8}
t = {'d': 6, 'c': 4}
print({**y, **t})  # 字典拆分，关键字

y = {'a': 10, 'b': 8}
t = {'d': 6, 'c': 4}
f = dict(y)  # 字典构造器
f.update(t)  # 更新
print(f)

y = {'a': 10, 'b': 8}
t = {'d': 6, 'c': 4}
c = dict(list(y.items()) + list(t.items()))
print(c)
