我在数据框中有一列，我正在尝试从字符串中提取 8 位数字。我该怎么做

    Input
 Shipment ID
20180504-S-20000
20180514-S-20537
20180514-S-20541
20180514-S-20644
20180514-S-20644
20180516-S-20009
20180516-S-20009
20180516-S-20009
20180516-S-20009

预期产出

Order_Date
20180504
20180514
20180514
20180514
20180514
20180516
20180516
20180516
20180516

我尝试了下面的代码，但没有用。

data['Order_Date'] = data['Shipment ID'][:8]

我在数据框中有 2 列。我想在几分钟内计算 2 列的差异并将结果写入新列

Input

Planned Pickup date/time    Actual Pickup date/time      
07/05/2018 09:28:00         07/05/2018 09:33:15               
14/05/2018 17:00:00         15/05/2018 08:44:08               
15/05/2018 17:00:00         15/05/2018 10:52:50              
15/05/2018 17:00:00         15/05/2018 15:03:34             
15/05/2018 17:00:00         15/05/2018 15:03:34              
16/05/2018 17:00:00         16/05/2018 16:00:38   

我想在几分钟内计算实际和计划取货的差异，并将结果写入数据帧中名为 data['time difference']

Expected Output

Planned Pickup date/time    Actual Pickup date/time      Time Difference
07/05/2018 09:28:00         07/05/2018 09:33:15               5
14/05/2018 17:00:00         15/05/2018 08:44:08               944
15/05/2018 17:00:00         15/05/2018 10:52:50              -368
15/05/2018 17:00:00         15/05/2018 15:03:34              -117
15/05/2018 17:00:00         15/05/2018 15:03:34              -117
16/05/2018 17:00:00         16/05/2018 16:00:38              -60

这如何在熊猫中完成

我想根据条件过滤熊猫数据框中的时间戳列。

Input

Pickup date/time      
07/05/2017 09:28:00                     
14/05/2017 15:32:20                     
15/05/2018 17:00:00                    
15/05/2018 11:20:09                    
23/06/2018 22:00:00                   
29/06/2018 16:10:02  

我想基于条件时间戳大于16:00:00在数据框中创建另一列

Expected Output

   Pickup date/time      Pickup  
    07/05/2017 09:28:00      On-time                 
    14/05/2017 15:32:20      On-time             
    15/05/2018 17:00:00      Delayed              
    15/05/2018 11:20:09      On-time              
    23/06/2018 22:00:00      Delayed           
    29/06/2018 16:10:02      Delayed 

我正在尝试提取包含特定关键字及其地理位置的所有推文。

例如，我要下载所有英文的推文，其中包含 来自“ france”和“ singapore”的关键字“ iphone ”

import tweepy
import csv
import pandas as pd
import sys

# API credentials here
consumer_key = 'INSERT CONSUMER KEY HERE'
consumer_secret = 'INSERT CONSUMER SECRET HERE'
access_token = 'INSERT ACCESS TOKEN HERE'
access_token_secret = 'INSERT ACCESS TOKEN SECRET HERE'

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth,wait_on_rate_limit=True,wait_on_rate_limit_notify=True)

# Search word/hashtag value 
HashValue = ""

# search start date value. the search will start from this date …
