教程上關(guān)于 format函數(shù) 指定對應(yīng)名稱的代碼舉例：

template = 'Hello {w}, Hello {c}, Hello , Hello {i}.'

world = 'World'

china = 'China'

beijing = 'Beijing'

imooc = 'imooc'

result = template.format(w = world, c = china, b = beijing, i = imooc)

print(result) # ==> Hello World, Hello China, Hello Beijing, Hello imooc.

和我使用的這種指定命名代碼

template='Hello {w}, \nThank you {c1}, \nMerci , \nDanke {c2}'

result=template.format(w='world',c1='china',b='beijing',c2='chongqing')

print(result)

都能達(dá)到相同的目的，他們在運算效率上有區(qū)別嗎？
