Quine 是指能够输出自己源代码的程序。可以考虑这样的变体，用语言 A 写的程序输出语言 B 的源代码，这份源代码运行之后可以输出原本语言 A 的源代码。

以下给出两种从 JavaScript 到 Python 的解法，第一种是在基础的 Quine 上稍作修改，第二种则是仿照第一种的思路，使用了两个“槽”。

(s => {
  tick = String.fromCharCode(96)
  quote = String.fromCharCode(34)
  console.log('print(' + quote + quote + quote + s + '(' + tip + s + tip + ')' + quote + quote + quote + ')')
})(`(s => {
  tick = String.fromCharCode(96)
  quote = String.fromCharCode(34)
  console.log('print(' + quote + quote + quote + s + '(' + tip + s + tip + ')' + quote + quote + quote + ')')
})`)

((p, s) => {
  quotes = String.fromCharCode(34)
  quotes = quotes + quotes + quotes
  console.log(p + '(' + quotes + p + quotes + ',' + quotes + s + quotes + ')')
})(`
def P(P, s):
  tick = chr(96)
  print(s + '(' + tick + P + tick + ',' + tick + s + tick + ')')

P`,`((p, s) => {
  quotes = String.fromCharCode(34)
  quotes = quotes + quotes + quotes
  console.log(p + '(' + quotes + p + quotes + ',' + quotes + s + quotes + ')')
})`)
