读取数据并使其可访问(通常称为数据加载)是使用本书中大多数工具的必要第一步。术语解析有时也用于描述加载文本数据并将其解释为表格和不同数据类型。我将专注于使用 pandas 进行数据输入和输出,尽管其他库中有许多工具可帮助读取和写入各种格式的数据。 输入和输出通常分为几个主要类别:读取文本文件和其他更高效的...
对于此示例,要使用的 URL 是randomuser.me/api/,这是您可以进行的最小的 API 调用: >>> >>> import requests >>> requests.get("https://randomuser.me/api/") <Response [200]> 在这个小例子,你导入的requests库,然后从URL中随机用户生成器API获取(或获得)的数据。但是您实际上看不到任何返回的数据...
Probably the most common use case is that you want to rate-limit a function that continuously checks whether a resource—like a web page—has changed. The @slow_down decorator will sleep one second before it calls the decorated function:Python decorators.py import functools import time # .....
You can define these rates using theRateclass.Rateclass has 2 properties only:limitandinterval frompyrate_limiterimportDuration,Ratehourly_rate=Rate(500,Duration.HOUR)# 500 requests per hourdaily_rate=Rate(1000,Duration.DAY)# 1000 requests per daymonthly_rate=Rate(10000,Duration.WEEK*4)# 10000 ...
