Question

如果我在word中看到此文件（文件-->；选项-->；显示-->；始终在屏幕上显示格式掩码，并选择它下面显示的所有选项）

 ....E-RECEIPT FOR  TRANSFER Of Funds...................................................................Payee Name...................
.....................................................................................................
AAA CHS.........................................................AAA CHS...........................Nickname ....etc 

Here (...) means spaces and in between lines it also shows paragraph symbols(¶) pillow cover and also at the end of file it is showing 3 paragraph symbols.

我希望输出类似（删除空格和段落符号）

E-RECEIPT FOR  TRANSFER FUNDS
Payee Name:                                                   AAA CHS 
Nickname:                                                     AAA CHS 
Credit Account No::                                           AAAA0000006666
...
...

我试着做了如下的事情

file=open("c:\\temp1\\tt1.txt", "r+")
for line in file.readlines():
    print(line.strip())
file.close()

它不起作用。请注意，我不想删除单词之间的空格，我想删除行之间的空格/特殊字符

第二，虽然这不是要求，但我可以在“：”或“：”前后只放一个空格吗

E-RECEIPT FOR  TRANSFER FUNDS
Payee Name : AAA CHS 
Nickname : AAA CHS 
Credit Account No :: AAAA0000006666

…等等

Answer 1

使用此方便功能：

import re
def text_processor(s):
    # s = your text
    return '\n'.join(str.split(re.sub('\s{2,}', ' ', re.sub('\n\n', '|\n', s.replace('::',':'))), '|')).replace(':', ' :')

示例：

# s = your text
# assuming you are reading in from a file: 'data.txt'
# with open('data.txt', 'r') as f:
#    s = f.read()
print(text_processor(s))

输出：

E-RECEIPT FOR TRANSFER FUNDS 
 Payee Name : AAA CHS 
 Nickname : AAA CHS 
 Credit Account No : AAAA0000006666 
 Remarks : 4869 
 Debit Account : 99999999999999 
 Date : 05 May '20 
 Amount : INR 4,869.00 (Rupees Four Thousand Eight Hundred Sixty Nine and Zero Paisa only)

print(s)

从Python打开Docx文件

参考：source

import docx2txt

# read in word file
s = docx2txt.process("data.docx")

# Copy pasting the dummy data into a docx file
# and trying to read and correcting the data 
# requires the following fix

print(text_processor(s).replace(' \n \n ', '\n'))
