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. 1802) を取り組んでみる。

SHARPEN YOUR PENCIL(No. 1802)

コード(Emacs)

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

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

new_phrase = ''.join(plist[1:3])
new_phrase += plist[5] + plist[4] + plist[7] + plist[6]

print(plist)
print(new_phrase)

入出力結果(Terminal, IPython)

$ ./sample2.py
Don't panic!
