在python中用非字符串值替换子字符串

Question

我知道我们有一个替换方法用另一个字符串替换字符串中的子字符串.但我想要的是用一些非字符串(可以是任何数据类型)值替换给定字符串中的一些子字符串.

示例 -

string1='My name is val1. My age is val2 years. I was born on val3'
val1='abc'
val2=40
val3= datetime.date(1980, 1, 1)

有任何想法吗？？

谢谢!!

用途str.format:

>>> string1 = 'My name is {0}. My age is {1} years. I was born on {2}'
>>> string1.format('abc', 40, datetime.date(1980, 1, 1))
'My name is abc. My age is 40 years. I was born on 1980-01-01'
