如何在python中将字典键映射到变量？

my_dict = {'key1': 'value1', 'key2': 'value2'}
var1 = my_dict['key1']
var2 = my_dict['key2']
print(var1)  # 输出：value1
print(var2)  # 输出：value2

my_dict = {'key1': 'value1', 'key2': 'value2'}
var1, var2 = my_dict['key1'], my_dict['key2']
print(var1)  # 输出：value1
print(var2)  # 输出：value2
