Python表格输出长数据自动换行[最佳实践]

解析

用到PrettyTable来打印表格

然后用到textwrap来处理自动换行

注意事项

如果是字典类型（或者其他类型），需要先 str(your_dict) , 然后再填入fill, 不然width不生效

代码演示

#!/bin/python3
# coding: utf-8
import prettytable
from textwrap import fill
from prettytable import ALL as ALL
items_table = prettytable.PrettyTable(hrules=ALL)
items_table.field_names = ["id", "name", "comment"]

items = [
    {
        "id": "1",
        "name": "Alvina Skiles",
        "comment": 'Dolor qui rerum est sed. Sed ipsa repudiandae et. Non explicabo voluptas impedit rerum dignissimos. Minima voluptatibus'
    },
    {
        "id": "2",
        "name" : 'Chasity Lakin',
        "comment": 'Nesciunt ea voluptatem rerum eos rerum ut soluta. Animi totam rerum fugiat consectetur odio et repellendus.'
    },
    {
        "id": "3",
        "name" : 'Miss Brennan Kiehn',
        "comment": 'Nulla placeat saepe voluptatem molestias dolores ex. Reiciendis nostrum adipisci qui enim explicabo.'
    },
]


for item in items:
    # 如果是字典类型，需要先 str(your_dict) , 然后再填入fill, 不然width不生效
    items_table.add_row([item["id"], item["name"], fill(item["comment"], width=50)])

print(items_table)

运行结果
