我正在寻找一种方法来搜索文本文件以获取作者所做的报价,然后将其打印出来。到目前为止我的脚本:
import re
#searches end of string
print re.search('"$', 'i am searching for quotes"')
#searches start of string
print re.search('^"' , '"i am searching for quotes"')
我想做什么
import re
## load text file
quotelist = open('A.txt','r').read()
## search for strings contained with quotation marks
re.search ("-", quotelist)
## Store in list or Dict
Dict = quotelist
## Print quotes
print Dict
我也试过
import re
buffer = open('bbc.txt','r').read()
quotes = re.findall(r'.*"[^"].*".*', buffer)
for quote in quotes:
print quote
# Add quotes to list
l = []
for quote in quotes:
print quote
l.append(quote)

开发一个正则表达式,匹配您希望在带引号的字符串中看到的所有预期字符。然后使用findall
中的python方法re
查找匹配的所有匹配项。
import re
buffer = open('file.txt','r').read()
quotes = re.findall(r'"[^"]*"',buffer)
for quote in quotes:
print quote
在“和”之间搜索需要unicode-regex搜索,例如:
quotes = re.findall(ur'"[^\u201d]*\u201d',buffer)
对于使用“和”可互换的报价终止
的文件quotes = re.findall(ur'"[^"^\u201d]*["\u201d]', buffer)

您不需要正则表达式来查找静态字符串。您应该使用此Python习惯用于查找字符串:
>>> haystack = 'this is the string to search!'
>>> needle = '!'
>>> if needle in haystack:
print 'Found', needle
创建列表很简单 -
>>> matches = []
存储匹配也很容易......
>>> matches.append('add this string to matches')
这应该足以让你入门。祝你好运!
解决以下评论的附录......
l = []
for quote in matches:
print quote
l.append(quote)
