如何停止python format（）中的重复

Question

我有一个字符串如下：

”这1只是1，而1只是一个数字。 1 +1等于2”

当我想使用python格式时，它将类似于：

var = 1
test = "This {} is just a {} and {} is just a number. And {} + {} is equal to 2".format(var,var,var,var,var)

但是我想知道python中是否可以快速替换str.format（）以避免重复。像这样：

test = "This {} is just a {} and {} is just a number. And {} + {} is equal to 2".format(var*)
