如何在python中叠加？

a = 5
b = 3
c = a + b
print(c)  # 输出结果为8

str1 = "Hello"
str2 = "World"
str3 = str1 + str2
print(str3)  # 输出结果为"HelloWorld"

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = list1 + list2
print(list3)  # 输出结果为[1, 2, 3, 4, 5, 6]

tuple1 = (1, 2, 3)
tuple2 = (4, 5, 6)
tuple3 = tuple1 + tuple2
print(tuple3)  # 输出结果为(1, 2, 3, 4, 5, 6)

dict1 = {"a": 1, "b": 2}
dict2 = {"b": 3, "c": 4}
dict3 = {**dict1, **dict2}
print(dict3)  # 输出结果为{"a": 1, "b": 3, "c": 4}
