如何使用 python 模板字符串格式化货币?我的目标是生成以下字符串:
'Hello Johnny. It is $10'
我尝试了以下方法:
from string import Template
d = {'name': 'Johnny', 'cost': 10}
Template('Hello ${name}. It is ${cost}').substitute(d)
# 'Hello Johnny. It is 10'
Template('Hello ${name}. It is $${cost}').substitute(d)
# 'Hello Johnny. It is ${cost}'
Template('Hello ${name}. It is $$cost').substitute(d)
# 'Hello Johnny. It is $cost'
