python - Is there a way to insert a list into the .format method in python?

Question

I want to do something like:

list = [1,2,3]
valstring = "one: {}, two: {}, three: {}".format(list)
print(valstring)

result:

one: 1, two: 2, three: 3

Is something like this possible? I know I can achieve a similar result by using .format(list[0], list[1], list[2]) but I have a long list so I'd prefer not to.

是的，使用星号（ Python 中*所谓的“解包”）：

lst = [1,2,3]
valstring = "one: {}, two: {}, three: {}".format(*lst)
print(valstring)

印刷：

one: 1, two: 2, three: 3
