How can I search for a text and if matched delete the entire line, preferably in regex.
如何搜索文本,如果匹配则删除整行,最好是在正则表达式中。
What I have tried so far:
到目前为止我尝试了什么:
My file:
我的档案:
wait => '10',
Trial one
试用一个
data = re.sub(r"^.*wait.*$","",data) #does not work
Trial two:
试用二:
data = re.sub(r".+/wait/.+","",data) #does not work

Your regexp
is not correct. Try this:
你的正则表达式是不正确的。尝试这个:
import re print re.sub(".*wait.*\n",'',"""wait => '10', wait => '10', Other data wait => '10', """,flags=re.M)

re.MULTILINE
When specified, the pattern character '^' matches at the beginning of the string and at the beginning of each line (immediately following each newline); and the pattern character '$' matches at the end of the string and at the end of each line (immediately preceding each newline). By default, '^' matches only at the beginning of the string, and '$' only at the end of the string and immediately before the newline (if any) at the end of the string.
指定时,模式字符'^'匹配字符串的开头和每行的开头(紧跟在每个换行符之后);模式字符'$'在字符串的末尾和每行的末尾(紧接在每个换行符之前)匹配。默认情况下,'^'仅匹配字符串的开头,'$'仅匹配字符串的结尾,紧接在字符串末尾的换行符(如果有)之前。
