python 對txt文字的去重處理

總結日常工作需要經常對資料進行去重的處理，在這裡簡單記錄分享下

import os

應事先在將txt檔案放在對應路徑下

import os

path =
'./tutu'
if not os.path.
exists
(path)
: 
os.makedirs
(path)
f3 =
open
(f"./tutu/a.txt"
,"r"
,encoding=
'utf-8'
)text_list =
s =set()
document = f3.
readlines()
document_num =
int(
len(document)
)print
('原條數：'
+str
(document_num)
)print
('***************=去重中***************='
)content =
[x.strip()
for x in document]
# print(content)
for x in range(0
,len
(content)):
url = content[x]
if url not in s:
s.add(url)
text_list.
(url)
filename =
int(
len(text_list)
)print
('現條數：'
+str
(filename)
)print
('減少了：'
+str
(document_num-filename )
)with open
(f'./tutu/b.txt'
,'a+'
,encoding=
'utf-8'
) as f:
for i in range
(len
(text_list)):
# s = str(i).split()
s =str(text_list[i]
) s = s +
'\n'
f.write
(s)print
('***************=儲存檔案成功***************='
)

import os

path =
'./tutu'
if not os.path.
exists
(path)
: os.
makedirs
(path)
print
('***************=讀取中***************='
)for filename in os.
listdir
(f"./tutu/"):
print
(filename)
with open
(f"./tutu/"
+filename,encoding=
'utf-8'
) as f: #讀取每個檔案
for line in f.
readlines()
: #將每個檔案文字同意逐行寫入乙個word中
with open
(f"./tutu/全部資料整理.txt"
,"a+"
,encoding=
'utf-8'
) as mom:
mom.
write
(line)
print
('***************=已完成txt讀取並寫入新txt***************='
)f3 =
open
(f"./tutu/全部資料整理.txt"
,"r"
,encoding=
'utf-8'

if url not in s:
s.add(url)
text_list.
(url)
filename =
int(
len(text_list)
)print
('現條數：'
+str
(filename)
)print
('減少了：'
+str
(document_num-filename )
)f3.
close()
with open
(f'./tutu/全部資料整理(去重後).txt'
,'a+'
,encoding=
'utf-8'
) as f:
for i in range
(len
(text_list)):
# s = str(i).split()
s =str(text_list[i]
) s = s +
'\n'
f.write

finger print 文字去重

任何一段資訊文字，都可以對應乙個不太長的隨機數，作為區別它和其它資訊的指紋 fingerprint 只要演算法設計的好，任何兩段資訊的指紋都很難重複，就如同人類的指紋一樣。資訊指紋在加密 資訊壓縮和處理中有著廣泛的應用。string content2 卓爾防線繼續傷筋動骨 隊長梅方出場再補漏說起來卓...
