Head First Python (Paul Barry (著)、O'Reilly Media)のChapter 2.(List Data: Working with Ordered Data)、Reviewing Our Experiments の SHARPEN YOUR PENCIL(No. 1567) を取り組んでみる。

SHARPEN YOUR PENCIL(No. 1567)

コード(Emacs)

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

phrase = "Don't panic!"
plist = list(phrase)
print(phrase)
print(plist)

for _ in range(4):
    plist.pop()

plist.pop(0)
plist.remove("'")
plist.extend([plist.pop(), plist.pop()])
plist.insert(2, plist.pop(3))

new_phrase = ''.join(plist)
print(plist)
print(new_phrase)

入出力結果(Terminal, IPython)

$ ./sample1.py
Don't panic!
