How to add key-value pairs to an empty dictionary in Python.

To add key-value pairs to an empty dictionary, you can use the following two methods:

Option 1:
Method 1: Adding key-value pairs using the index operator[].

# 创建一个空字典
my_dict = {}

# 添加键值对
my_dict["key1"] = "value1"
my_dict["key2"] = "value2"

print(my_dict)

Option 2: Adding key-value pairs using the update() method.

# 创建一个空字典
my_dict = {}

# 使用update()方法添加键值对
my_dict.update({"key1": "value1", "key2": "value2"})

print(my_dict)

You can add key-value pairs to an empty dictionary using any method.
