Pythonで表の文字列長を揃えて表示(CLI)

Last updated at Posted at 2019-07-04

自分用にメモ。

Python 2.7用

表(2次元のリスト)のデータをPythonで整形する

マルチバイト文字は考慮しないで、lenとmaxを使って各列の最大長を取得して揃える

print_table.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
table = [
  ["column1", "column2", "column3"],
  ["abc", "defghijklm", "nopqrstuvwxyz"],
  ["abcdefghi","jklmn", "opqrstuvwxyz"],
]

align_table = [
  ("column1", "r"),
  ("column2", "l"),
  ("column3", "r"),
]

"""
  文字列長が合わないときは空白で埋める
"""
def adjust_length(input_str, adj_length, align='r'):
    return '{:{}{}s}'.format(input_str, {'r': '>', 'l': '<'}[align], adj_length)

max_length = [ max([ len(y) for y in x ]) for x in zip(*table) ]

print("\n".join([
  " ".join([
    adjust_length(x,mlen,align) 
    for x,mlen,align in zip(row,max_length,zip(*align_table)[1])
  ])
  for row in table
]))
  

実行結果

$ python print_table.py
  column1 column2          column3
      abc defghijklm nopqrstuvwxyz
abcdefghi jklmn       opqrstuvwxyz
