string-formatting - Python : replacing several %s with the same variable 中的输出格式

Question

我正在尝试维护/更新/重写/修复一些看起来有点像这样的 Python:

variable = """My name is %s and it has been %s since I was born.
              My parents decided to call me %s because they thought %s was a nice name.
              %s is the same as %s.""" % (name, name, name, name, name, name)

整个脚本都有这样的小片段，我想知道是否有更简单(更 Pythonic？)的方式来编写这段代码。我发现了一个这样的例子，它把同一个变量替换了大约 30 次，感觉很丑。

解决(在我看来)丑陋的唯一方法是把它分成很多小块吗？

variable = """My name is %s and it has been %s since I was born.""" % (name, name)
variable += """My parents decided to call me %s because they thought %s was a nice name.""" % (name, name)
variable += """%s is the same as %s.""" % (name, name)

Answer 1

改用字典。

var = '%(foo)s %(foo)s %(foo)s' % { 'foo': 'look_at_me_three_times' }

或 format 带有明确的编号。

var = '{0} {0} {0}'.format('look_at_meeee')

好吧，或者 format 带有命名参数。

var = '{foo} {foo} {foo}'.format(foo = 'python you so crazy')
