Python-like PHP htmlspeialchars () filter String functions

1: Escape () function using the CGI module

>>>Import CGI>>> Stra ='<foo>\nfoo\t "Bar"'>>> Resa =Cgi.escape (stra)>>>print (RESA)&lt;foo&Gt;foo"Bar">>> STRB ="<foo>\nfoo\t ' Bar '">>> Resb =Cgi.escape (STRB)>>>print (RESB)&lt;foo&Gt;foo'Bar'

The single and double quotation marks in the visible string are not escaped as character entities, viewing the document

Escape (S, quote=None)    "&" "<""  >" to html-safe sequences.      is true, the quotation mark character (")is     also translated.

If a quote=true is given, then the double quotes are escaped, but the single quotation marks do not;

RESAA = Cgi.escape (stra,true)>>> Print (RESAA)<foo>foo    & quot;bar"    #这里转义了双引号>>> resbb = cgi.escape (strb,true)>>> Print (RESBB)<foo >foo    'bar' # There's no escaping here

2: Escape method using HTML module

>>> Import HTML'<foo>\nfoo\t ' bar' >>> resa =  Html.escape (stra)>>> Print (resa)&lt;foo&gt;foo    &quot;bar&　　quot;  #这里做了转义处理   "<foo>\nfoo\t ' bar">>> resb =  Html.escape (STRB)>>> Print (resb)&lt;foo&gt;foo    

The escape method of the HTML module defaults to handling single and double quotes, the document:

 Escape (S, Quote=true) Replace special characters   " &  " ,  <  "  and  " >  "  to Html-safe sequences. If the optional flag quote  is  true  ( The default  ), the quotation mark characters, both  double  quote ( " ) and single quote (') characters is also  translated.
