如何格式化美麗湯和硒的輸出？

Question

我檢索使用下面的代碼從一個網站的經濟數據：

from bs4 import BeautifulSoup 
from selenium import webdriver 

url = 'https://www.fxstreet.com/economic-calendar' 

driver = webdriver.Chrome() 
driver.get(url) 
html = driver.page_source 
soup = BeautifulSoup(html, 'lxml') 

for tr in soup.findAll('tr',{'class':['fxst-tr-event', 'fxst-oddRow', 'fxit-eventrow', 'fxst-evenRow', 'fxs_cal_nextEvent']}): 
    event = tr.find('div', {'class': 'fxit-event-title'}).text 
    currency = tr.find('div', {'class': 'fxit-event-name'}).text 
    actual = tr.find('div', {'class': 'fxit-actual'}).text 
    forecast = tr.find('div', {'class': 'fxit-consensus'}).text 
    previous = tr.find('div', {'class': 'fxst-td-previous fxit-previous'}).text 
    time = tr.find('div', {'class': 'fxit-eventInfo-time fxs_event_time'}).text 
    volatility = tr.find('div', {'class': 'fxit-eventInfo-vol-c fxit-event-info-desktop'}).span['title'] 

    print(u'\t{}\t{}\t{}\t{}').format(time, currency, event, volatility) 

從打印語句的輸出如下：

23:30 
AUD          
AiG Performance of Construction Index (Jul) 
    Moderate volatility expected 
    23:50 
JPY          
JP Foreign Reserves (Jul) 
    Low volatility expected 
    24h 
CAD          
August Civic Holiday 
    No volatility expected 
    01:30 
AUD          
ANZ Job Advertisements (Jun) 
    Low volatility expected 
    n/a 
CNY          
Foreign Exchange Reserves (MoM) (Jul) 
    Low volatility expected 
    05:00 
JPY          
Coincident Index (Jun)Preliminar 
    Moderate volatility expected 
    05:00 

是否有可能格式化這個輸出，使得打印在線，如下所示？

23:30 AUD AiG Performance of Construction Index (Jul) Moderate volatility expected 
    23:50 JPY JP Foreign Reserves (Jul)      Low volatility expected 
    24h  CAD August Civic Holiday       No volatility expected 
    01:30 AUD ANZ Job Advertisements (Jun)     Low volatility expected 
    n/a  CNY Foreign Exchange Reserves (MoM) (Jul)   Low volatility expected 
    05:00 JPY Coincident Index (Jun)Preliminary    Moderate volatility expected 

最終目標是剪切此輸出並將其粘貼到Excel文件中。提前致謝！

Answer 1

嘗試去除換行是這樣的：

from bs4 import BeautifulSoup 
from selenium import webdriver 

url = 'https://www.fxstreet.com/economic-calendar' 

driver = webdriver.Chrome() 
driver.get(url) 
html = driver.page_source 
soup = BeautifulSoup(html, 'lxml') 

for tr in soup.findAll('tr',{'class':['fxst-tr-event', 'fxst-oddRow', 'fxit-eventrow', 'fxst-evenRow', 'fxs_cal_nextEvent']}): 
    event = tr.find('div', {'class': 'fxit-event-title'}).text 
    currency = tr.find('div', {'class': 'fxit-event-name'}).text 
    actual = tr.find('div', {'class': 'fxit-actual'}).text 
    forecast = tr.find('div', {'class': 'fxit-consensus'}).text 
    previous = tr.find('div', {'class': 'fxst-td-previous fxit-previous'}).text 
    time = tr.find('div', {'class': 'fxit-eventInfo-time fxs_event_time'}).text 
    volatility = tr.find('div', {'class': 'fxit-eventInfo-vol-c fxit-event-info-desktop'}).span['title'] 

    print(u'\t{}\t{}\t{}\t{}').format(time.strip(), currency.strip(), event.strip(), volatility.strip()) 

這樣每個字符串將不換行。

作爲對其他答案的補充，由於您提到「最終目標是剪切該輸出並將其粘貼到Excel文件中」，您也可能有興趣從數據生成.csv，因此它可能很容易導出到Excel，而不是複製粘貼，import csv後，你需要你的循環更改爲：

with open("data.csv", "w") as csv_file: 
    for tr in soup.findAll('tr',{'class':['fxst-tr-event', 'fxst-oddRow', 'fxit-eventrow', 'fxst-evenRow', 'fxs_cal_nextEvent']}): 
     event = tr.find('div', {'class': 'fxit-event-title'}).text 
     currency = tr.find('div', {'class': 'fxit-event-name'}).text 
     actual = tr.find('div', {'class': 'fxit-actual'}).text 
     forecast = tr.find('div', {'class': 'fxit-consensus'}).text 
     previous = tr.find('div', {'class': 'fxst-td-previous fxit-previous'}).text 
     time = tr.find('div', {'class': 'fxit-eventInfo-time fxs_event_time'}).text 
     volatility = tr.find('div', {'class': 'fxit-eventInfo-vol-c fxit-event-info-desktop'}).span['title'] 

     line = [time.strip(),currency.strip(),event.strip(),volatility.strip()] 
     writer = csv.writer(csv_file, delimiter=',') 
     writer.writerow(line) 
     print(line)
