【Python】文字列をn文字に分割する

Last updated at Posted at 2021-11-12

環境

Python 3.9.2

関数

import re

def split_n(text, num, fraction=True):
    if fraction:
        return re.findall(f'.{{1,{num}}}', text) 
    else:
        return re.findall(f'.{{{num}}}', text)

利用例

# 端数も返す
print(split_n("abcdefgh", 3))
# => ['abc', 'def', 'gh']

# 端数を返さない
print(split_n("abcdefgh", 3, fraction=False))
# => ['abc', 'def']

関数化までは不要な場合

import re

# 端数も返す
print(re.findall('.{1,3}', "abcdefgh"))
# => ['abc', 'def', 'gh']

# 端数を返さない
print(re.findall('.{3}', "abcdefgh"))
# => ['abc', 'def']
