17. １列目の文字列の異なり
1列目の文字列の種類（異なる文字列の集合）を求めよ．確認にはcut, sort, uniqコマンドを用いよ．
Pythonコード
import sys path = sys.argv[1] with open(path) as f: s = set() for l in f: s.add(l.split('\t')[0]) for e in s: print(e)
確認用UNIXコマンド
私の環境は少し特殊(fish)なので、もしかしたら動かないかも。
python NPL100_17.py ../popular-names.txt | sort > output_python.txt cut -f 1 ../popular-names.txt | sort | uniq > output_unix.txt diff -s output_python.txt output_unix.txt
