使用python将单词移动到行尾

我正在解析一个 HTML,我得到一个Array字符串,我正在尝试清理它,然后将其放入pdf中.在这个级别,我想把@X开始的所有单词移到行尾,这样我最终可以得到所有的@X对齐.

Hello World @Xabs
Hello World                                   @Xz
Hello World  @Xss
Hello World         @Xssa
Hello World       @Xqq
Hello World             @Xsasas

我希望作为输出：

Hello World                                        @Xabs
Hello World                                        @Xz
Hello World                                        @Xss
Hello World                                        @Xssa
Hello World                                        @Xqq
Hello World                                        @Xsaxs

有任何想法吗？

到目前为止我所拥有的：

# encoding=utf8 
import sys
reload(sys) 
#import from lxml import html 
from bs4 import BeautifulSoup as soup 
import re import codecs 
sys.setdefaultencoding('utf8') 

# Access to the local URL(Html file) f=codecs.open("C:\...\file.html",'r') 
page = f.read() 
f.close() 

#html 
parsing page_soup = soup(page,"html.parser") 
tree = html.fromstring(page) # extract the important arrays of string 

a_s= page_soup.find_all("td",{"class" :"row_cell"})
for a in a_s:
    result = a.text.replace("@X","")
    print(final_result)

解决方法

与@ blue_note的答案非常相似,但使整个解决方案更加自动化：

import re

lines = ['Hello World @Xabs','Hello World                                   @Xz','Hello World  @Xss','Hello World         @Xssa','Hello World       @Xqq','Hello World             @Xsasas']

aligned_lines = []
for line in lines:
    match = re.findall('@X\w+',line)[0]
    line = line.replace(match,'')
    aligned_lines.append('%-50s %s' % (line,match))

aligned_lines

['Hello World                                        @Xabs','Hello World                                        @Xz','Hello World                                        @Xss','Hello World                                        @Xssa','Hello World                                        @Xqq','Hello World                                        @Xsasas']
