如果字典键存在，如何以指定的格式打印列表的值？

if key in my_dict:
    # 执行相应的操作

value = my_dict[key]

print("The value is: {}".format(value))

print(f"The value is: {value}")

if key in my_dict:
    value = my_dict[key]
    print("The value is: {}".format(value))

if key in my_dict:
    value = my_dict[key]
    print(f"The value is: {value}")
