Revision 9. </p> <p>Useful if you need to replace many different characters with all of the same character. Can accept an unlimited number of request to replace.</p> <p>Does not work with words, only characters. You can, however, replace single characters with words. I may go back and re-implement it using tuples for the keys, but this would make searching the text for any matches pretty expensive, I'd imagine. At that point, it's mostly a job for a regex, and those tools already exist.</p> lreplace() and rreplace(): Replace the beginning and ends of a strings (Python) 2010-06-04T02:18:48-07:00Dan McDougallhttp://code.activestate.com/recipes/users/4169722/http://code.activestate.com/recipes/577252-lreplace-and-rreplace-replace-the-beginning-and-en/ <p style="color: grey"> Python recipe 577252 by <a href="/recipes/users/4169722/">Dan McDougall</a> (<a href="/recipes/tags/regex/">regex</a>, <a href="/recipes/tags/replace/">replace</a>, <a href="/recipes/tags/string/">string</a>). </p> <p>Python newbies will often make the following mistake (I certainly have =):</p> <pre class="prettyprint"><code>&gt;&gt;&gt; test = """this is a test: ... tis the season for mistakes.""" &gt;&gt;&gt; for line in test.split('\n'): ... print line.lstrip('this') ... is a test the season for mistakes. </code></pre> <p>The mistake is assuming that lstrip() (or rstrip()) strips a string (whole) when it actually strips all of the provided characters in the given string. Python actually comes with no function to strip a string from the left-hand or right-hand side of a string so I wrote this (very simple) recipe to solve that problem. Here's the usage:</p> <pre class="prettyprint"><code>&gt;&gt;&gt; test = """this is a test: ... tis the season for mistakes.""" &gt;&gt;&gt; for line in test.split('\n'): ... print lreplace('this', '', line) ... is a test tis the season for mistakes. </code></pre> <p>I really wish Python had these functions built into the string object. I think it would be a useful addition to the standard library. It would also be nicer to type this:</p> <pre class="prettyprint"><code>line.lreplace('this', '') </code></pre> <p>Instead of this:</p> <pre class="prettyprint"><code>lreplace('this','',line) </code></pre> C# String.Replace with a char array (Java) 2010-12-24T09:58:35-08:00John Hurlimanhttp://code.activestate.com/recipes/users/4174599/http://code.activestate.com/recipes/577516-c-stringreplace-with-a-char-array/ <p style="color: grey"> Java recipe 577516 by <a href="/recipes/users/4174599/">John Hurliman</a> (<a href="/recipes/tags/csharp/">csharp</a>, <a href="/recipes/tags/replace/">replace</a>, <a href="/recipes/tags/string/">string</a>). </p> <p>Takes a string and replaces all characters matching a given array with a given string</p> Improved range function (Python) 2010-06-07T01:50:20-07:00Sunjay Varmahttp://code.activestate.com/recipes/users/4174115/http://code.activestate.com/recipes/577256-improved-range-function/ <p style="color: grey"> Python recipe 577256 by <a href="/recipes/users/4174115/">Sunjay Varma</a> (<a href="/recipes/tags/float/">float</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/range/">range</a>, <a href="/recipes/tags/replace/">replace</a>). Revision 2. </p> <p>While using the built-in range function a while ago. I found an odd (perhaps bug) where the range function couldn't use float steps. I am not sure if that was intended for simplicity or not, but I wrote my own range function that goes beyond that anyway.</p> REAL case insensitive string replace (Python) 2009-04-25T15:48:50-07:00Jonas Haaghttp://code.activestate.com/recipes/users/4169206/http://code.activestate.com/recipes/576715-real-case-insensitive-string-replace/ <p style="color: grey"> Python recipe 576715 by <a href="/recipes/users/4169206/">Jonas Haag</a> (<a href="/recipes/tags/case/">case</a>, <a href="/recipes/tags/case_insensitive/">case_insensitive</a>, <a href="/recipes/tags/replace/">replace</a>, <a href="/recipes/tags/str/">str</a>).
