How do you define variable types in Python?

In Python, the type of a variable is determined by its value, so there is no need to explicitly specify the variable type. Python is a dynamic typing language, meaning it will automatically infer the type of a variable based on its assignment. For example, when you assign an integer to a variable, Python will set the variable type as integer. Here are some examples:

# 定义整数类型变量
x = 10

# 定义浮点数类型变量
y = 3.14

# 定义字符串类型变量
name = "John"

# 定义布尔类型变量
is_true = True

# 定义列表类型变量
my_list = [1, 2, 3]

# 定义字典类型变量
my_dict = {"name": "John", "age": 30}

In the example above, the type of a variable is automatically determined based on its assigned value. You can use the type() function to check the variable’s type, for example type(x) will return .
