如何一次打印克隆列表并将它们加载到Python中的字典中？

问题描述：

cs 124456 powerful 
cs 124456 powerful 
me  125454 easy 
me 125455 easy 
me 125455 easy 
ec 125555 done 
ec 127678 fine 
ec 127678 fine 
ci 127678 fine 
ci 127678 fine 
eee 125678 good 
eee 125678 good 
eee 125678 good 
eee 125678 bad`

预期输出：

no.name reg perform 
1.cs 124456 powerful 
2.me 125454 easy 
3.me 125455 easy 
4.ec 125555 done 
5.ec 127678 fine 
6.ci 127678 fine 
7.eee 125678 good 
8.eee 125678 bad

我的代码：

import os 
os.chdir("d:/filer") 
import re   
def first(line): 
    f=re.findall("[a-z]+",line,flags=0) 
    return f 
def num(line): 
    n=re.findall("\d{6}",line,flags=0) 
    return n 
with open("once.txt","r") as sa: 
    for line in sa.readlines(): 
      home=first(line) 
      number=num(line) 
      x=home[0] 
      y=number[0] 
      z=home[1] 
      if x!=0 and y!=0 and z!=0:  
      print [x,y,z]

我打开的文件，并通过行阅读线。然后我使用正则表达式提取这些数字和文本，并将其存储在带索引的列表中。现在我只想列出那些唯一且不克隆的列表。然后将它们加载到字典中。有人能帮助我吗？

为了防止克隆，你可以使用一个set()像这样：

results = set() # Construct a set 
with open("once.txt","r") as sa: 
    for line in sa.readlines(): 
      home=first(line) 
      number=num(line) 
      x=home[0] 
      y=number[0] 
      z=home[1] 
      if x!=0 and y!=0 and z!=0: 
      if (x,y,z) not in results: # Check if the set already contains the result 
       results.add((x,y,z)) # If it doesn't, add to the set and print. 
       print [x,y,z]

我也建议举办一些代码。你可以创建1个正则表达式，如下所示：

results = set() # Construct a set 
with open("once.txt","r") as sa: 
    count = 0 
    for line in sa: # No need for readlines() 
     match = re.match(r"(\w+)\s+(\d+)\s+(\w+)") 

     if match is None: 
      continue 

     result = match.groups() 
     if result not in results: # Check if the set already contains the result 
      count += 1 
      results.add(result) # If it doesn't, add to the set and print. 
      print count, result
