为了确保字符串按预期显示，我们可以使用 format() 方法对结果进行格式化。
Dace format()

Mafi
quantity = 3
itemno = 567
price = 52
myorder = "A na nuna {} takarun dake kisanan na numarinta {} dominan naira {} dollars."
print(myorder.format(quantity, itemno, price))
索引号
您可以使用索引号（花括号 {0} 内的数字）来确保将值放在正确的占位符中：
Mafi
quantity = 3
itemno = 567
price = 52
myorder = "I want {0} pieces of item number {1} for {2:.2f} dollars."
print(myorder.format(quantity, itemno, price))
此外，如果要多次引用相同的值，请使用索引号：
Mafi
age = 63
name = "Bill"
txt = "His name is {1}. {1} is {0} years old."
print(txt.format(age, name))
命名索引
您还可以通过在花括号 {carname} 中输入名称来使用命名索引，但是在传递参数值 txt.format(carname = "Ford") 时，必须使用名称：
Mafi
myorder = "I have a {carname}, it is a {model}."
print(myorder.format(carname = "Porsche", model = "911"))
