Head First Python (Paul Barry (著)、O'Reilly Media)のChapter 13.(Advanced Iteration: Looping Like Crazy) の SHARPEN YOUR PENCIL(No. 9129) を取り組んでみる。

SHARPEN YOUR PENCIL(No. 9129)

コード(Emacs)

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

print('1.')
data = list(range(1, 9))
print(data)

evens = [num for num in data if num % 2 == 0]
print(evens)

print('2.')
data = [1, 'one', 2, 'two', 3, 'three', 4, 'four']
print(data)

words = [num for num in data if isinstance(num, str)]
print(words)

print('3.')
data = list('So long and thanks for all the fish'.split())
print(data)
title = [word.title() for word in data]
print(title)

入出力結果(Terminal, IPython)

$ ./sample2.py
1.
[1, 2, 3, 4, 5, 6, 7, 8]
[2, 4, 6, 8]
2.
[1, 'one', 2, 'two', 3, 'three', 4, 'four']
['one', 'two', 'three', 'four']
3.
['So', 'long', 'and', 'thanks', 'for', 'all', 'the', 'fish']
['So', 'Long', 'And', 'Thanks', 'For', 'All', 'The', 'Fish']
