Question

我正在阅读文件，我想替换两个双引号之间出现的任何文字，如下所示：

如果文件输入是：

嗨，我是一个示例文件！＆＃34;嗨那里有示例文件。＆＃34;

＆＃34;我大多只是为了让这个报价变得有色！＆＃34;

输出应为：

嗨，我是一个示例文件！ [color = x]＆＃34;嗨有示例文件。＆＃34; [/ color]

[color = x]＆＃34;我大多只是为了让这个引用变得有色！＆＃34; [/ color]

我已经写了这三个模块来做到这一点，前两个工作，但最后一个没有。

第1单元：

__author__ = 'Joker'
import os
import sys
import re
import fileinput

print ("Text to search for:")
textToSearch = ( '" ' )

print ("Text to replace it with:")
textToReplace = ( '"[/color] ' )

print ("File to perform Search-Replace on:")
fileToSearch  = ( "D:\Coding projects\post edit\post.txt" )


tempFile = open( fileToSearch, 'r+' )

for line in fileinput.input( fileToSearch ):
    if textToSearch in line :
        print('Match Found')
    else:
        print('Match Not Found!!')
    tempFile.write( line.replace( textToSearch, textToReplace ) )
tempFile.close()

input( '\n\n Press Enter to exit...' )

第2单元：

__author__ = 'Joker'
import os
import sys
import re
import fileinput

print ("Text to search for:")
textToSearch = ( ' "' )

print ("Text to replace it with:")
textToReplace = ( ' [color=#66ccff]"' )

print ("File to perform Search-Replace on:")
fileToSearch  = ( "D:\Coding projects\post edit\post.txt" )

tempFile = open( fileToSearch, 'r+' )

for line in fileinput.input( fileToSearch ):
    if textToSearch in line :
        print('Match Found')
    else:
        print('Match Not Found!!')
    tempFile.write( line.replace( textToSearch, textToReplace ) )
tempFile.close()

input( '\n\n Press Enter to exit...' )

第3单元：

__author__ = 'Joker'
import os
import sys
import re
import fileinput

print ("Text to search for:")
textToSearch = ( r'\n"')

print ("Text to replace it with:")
textToReplace = (r'\n[color=#66ccff]"' )

print ("File to perform Search-Replace on:")
fileToSearch  = ( "D:\Coding projects\post edit\post.txt" )

tempFile = open( fileToSearch, 'r+' )

for line in fileinput.input( fileToSearch ):
    if textToSearch in line :
        print('Match Found')
    else:
        print('Match Not Found!!')
    tempFile.write( line.replace( textToSearch, textToReplace ) )
tempFile.close()

input( '\n\n Press Enter to exit...' )

加分：有没有办法将这三个模块的功能合二为一？

Answer 1

尝试使用re regular expression模块：

import re 

text = open(filename).read()  # read the entire file content

# define your tags here
opening_tag = '[color=x]'
closing_tag = '[/color]'

matches = re.findall(r'\"(.+?)\"',text)  # match text between two quotes
for m in matches:
  text = text.replace('\"%s\"' % m, '%s\"%s\"%s' % (opening_tag, m, closing_tag))  # override text to include tags

# write modified text with tags to file
with open(filename, 'w') as f:
  f.write(text)

#  for the input you specified, the new file should be:
>> [color=x]"Hi there example file."[/color]
>> [color=x]"I'm mostly just here to get this quote to be colored!"[/color]

Answer 2

结束使用@ Forge的答案作为灵感。所以他的主要功劳。然而，这就是我最终修复它的方式。包括最终结果：

import re 

string = open('post.txt').read()  # read the entire file content
cfile = open('character.txt').read() #Read character

#select a color
variable=raw_input('which character are you using?\n')
print variable
ini=cfile.find(variable)+(len(variable)+1)
rest=cfile[ini:]
search_enter=rest.find('\n')
color=str(rest[:search_enter])

# define your tags here
opening_tag = '[color=%s]' % (color)
closing_tag = '[/color]'

matches = re.findall(r'\"(.+?)\"',string)  # match text between two quotes
for m in matches:
    string = string.replace('\"%s\"' % (m), '\"%s%s%s\"' % (opening_tag, m, closing_tag))  # override text to include tags

print string

# write tagged text to file
with open('post.txt', 'w') as f:
  f.write(string)
