残プロ 第-7回 ~pythonで文字列操作~

Posted at

文字列strの操作

今回実装する操作は以下の2つです.

1.大文字で区切る ex)"EveryDay" → "Every" + "Day"
2.コンマ[,]で区切る ex)"one,two,three" → "one" + "two" + "three"

サンプル.py

文字列str型に対するメソッドsplitと正規表現モジュールreのfindall関数を使用します.
splitは区切り文字が含まれず,findallは含めることができます.

sample.py
import re

def separateStr(string):
    separated_comma = string.split(',')
    if type(separated_comma) == list:
        separated_upper = []
        for s in separated_comma:
            separated_upper.append(re.findall('[A-Z][a-z]+', s))
    else:
        separated_upper = re.findall('[A-Z][a-z]+', separated_comma)
    return separated_upper
