Python -检查变量是否已分配给函数或是否使用了默认变量

def my_function(my_variable=None):
    if my_variable is None:
        print("Variable is not assigned to a function or using default variable")
    else:
        print("Variable is assigned to a function")

my_function()  # 输出：Variable is not assigned to a function or using default variable
my_function(10)  # 输出：Variable is assigned to a function
