Python REPL 中默认的漂亮打印

问题描述

默认情况下如何在 REPL 上启用漂亮打印?

目前我使用 pprint.pprint() 函数来实现.

>>>pprint.pprint(数据){'SHIP_CATEGORY':''，'SHIP_QUANTITY': 1,'SHIP_SEPARATELY': 0,'SHIP_SUPPLEMENT': 0,'SHIP_SUPPLEMENT_ONCE': 0,'缩略图':''}

但我希望默认打印漂亮

>>>数据{'SHIP_CATEGORY':''，'SHIP_QUANTITY': 1,'SHIP_SEPARATELY': 0,'SHIP_SUPPLEMENT': 0,'SHIP_SUPPLEMENT_ONCE': 0,'缩略图':''}

我尝试了什么?
我在谷歌上搜索过.没有发现任何大多数结果指向 pprint 模块

解决方案

使用 sys.displayhook

导入pprint导入系统orig_displayhook = sys.displayhookdef myhook(值):如果值 != 无:__builtins__._ = 值pprint.pprint(值)__builtins__.pprint_on = lambda: setattr(sys, 'displayhook', myhook)__builtins__.pprint_off = lambda: setattr(sys, 'displayhook', orig_displayhook)

把上面的代码放到 PYTHONSTARTUP 如果你不这样做每次运行交互式 shell 时都要输入它.

用法:

>>>数据 = dict.fromkeys(range(10))>>>数据{0:无，1:无，2:无，3:无，4:无，5:无，6:无，7:无，8:无，9:无}>>>pprint_on()>>>数据{0:无，1:无，2:无，3:无，4:无，5:无，6:没有，7:没有，8:没有，9:无}>>>pprint_off()>>>数据{0:无，1:无，2:无，3:无，4:无，5:无，6:无，7:无，8:无，9:无}

How can i enable pretty print on the REPL by default?

Currently I do it by using pprint.pprint() function.

>>> pprint.pprint(data)
{'SHIP_CATEGORY': '',
 'SHIP_QUANTITY': 1,
 'SHIP_SEPARATELY': 0,
 'SHIP_SUPPLEMENT': 0,
 'SHIP_SUPPLEMENT_ONCE': 0,
 'THUMBNAIL': ''}

But I want pretty print by default

>>> data
{'SHIP_CATEGORY': '',
 'SHIP_QUANTITY': 1,
 'SHIP_SEPARATELY': 0,
 'SHIP_SUPPLEMENT': 0,
 'SHIP_SUPPLEMENT_ONCE': 0,
 'THUMBNAIL': ''}

What have I tried?
I searched on google. Didn't found anything most result points to pprint module

解决方案

Use sys.displayhook

import pprint
import sys

orig_displayhook = sys.displayhook

def myhook(value):
    if value != None:
        __builtins__._ = value
        pprint.pprint(value)

__builtins__.pprint_on = lambda: setattr(sys, 'displayhook', myhook)
__builtins__.pprint_off = lambda: setattr(sys, 'displayhook', orig_displayhook)

Put Above code to PYTHONSTARTUP if you don't want type it every time you run interactive shell.

Usage:

>>> data = dict.fromkeys(range(10))
>>> data
{0: None, 1: None, 2: None, 3: None, 4: None, 5: None, 6: None, 7: None, 8: None, 9: None}
>>> pprint_on()
>>> data
{0: None,
 1: None,
 2: None,
 3: None,
 4: None,
 5: None,
 6: None,
 7: None,
 8: None,
 9: None}
>>> pprint_off()
>>> data
{0: None, 1: None, 2: None, 3: None, 4: None, 5: None, 6: None, 7: None, 8: None, 9: None}
