Using editor

I don't know which editor you're using, but if it supports RegEx search and replace, you can try something like this:

<pre><code>Replace: print "(.*?)"
With: scribble( "\1" )
</code></pre>

I tested this in Notepad++.

Using Python

Alternatively, you can do it with Python itself:

<pre><code>import re

f = open( "code.py", "r" )
newsrc = re.sub( "print \"(.*?)\"", "scribble( \"\\1\" )", f.read() )
f.close()

f = open( "newcode.py", "w" )
f.write( newsrc )
f.close()
</code></pre>

Rather than replacing it, you could overload the print function!

In python 2.x this is not directly possible. But there are tools that convert python 2.x into python 3 code.

Run your code through the converter, then overload the print function.

Versions of python below 2.6 still support print functions (and hence overloading) by using from future. So once coverted you code should still work on older versions. Though it seems most if not using 3.x are using 2.7 so you might not need from future

Actually, you can convert all your <code>print</code> statements to <code>print()</code> functions using the <a href="http://docs.python.org/library/2to3.html" rel="nofollow">included <code>2to3</code> tool</a>. While this tool is normally used to convert a Python 2 program to a Python 3 program as completely as possible, it is actually a collection of small fixes, and you can choose which fixes to run. In your case, you can run only the <code>print</code> fixer by giving the argument <code>-f print</code> when you invoke <code>2to3</code>.

Here's an Emacs implementation that, by default, converts a print statement to a print function, with the option to change any statement to any function. I've tried to document it clearly, but please let me know if anything is unclear.
OP could use it interactively with <code>M-x my-statement-to-function RET scribble RET</code> or programmatically with <code>(my-statement-to-function &quot;print&quot; &quot;scribble&quot;)</code>.
<pre class="lang-lisp prettyprint-override"><code>(defun my-statement-to-function (&amp;optional statement func)
 &quot;Convert STATEMENT to FUNC.

For use with statements in Python such as 'print'. Converts
statements like,

 print \&quot;Hello, world!\&quot;

to a function like,

 print(\&quot;Hello, world\&quot;)

Also works generally so that the STATEMENT can be changed to any
FUNC. For instance, a 'print' statement,

 print \&quot;Hello, world!\&quot;

could be changed to a function,

 banana(\&quot;Hello, world!\&quot;)

Default STATEMENT is 'print'. Default FUNC is
STATEMENT (e.g. 'print'). Prompt for STATEMENT and FUNC when
called with universal prefix, `C-u'.&quot;
 (interactive &quot;p&quot;)
 (let* ((arg statement) ; statement argument overwritten, so preserve value
 ;; only prompt on universal prefix; 1 means no universal, 4 means universal
 (statement (cond ((eql arg 1) &quot;print&quot;) ; no prefix
 ((eql arg 4) (read-string &quot;Statement (print): &quot; &quot;&quot; nil &quot;print&quot;)))) ; C-u
 (func (cond ((eql arg 1) statement) ; no prefix
 ((eql arg 4) (read-string (concat &quot;Function &quot; &quot;(&quot; statement &quot;): &quot;) &quot;&quot; nil statement)))) ; C-u
 ;; [[:space:]]* -- allow 0 or more spaces
 ;; \$\&quot;\\|\'\$ -- match single or double quotes
 ;; \$\$ -- define capture group for statement expression; recalled with \\2
 (regexp (concat statement &quot;[[:space:]]*\$\&quot;\\|\'\$\$.*?\$\$\&quot;\\|'\$&quot;))

I'm using python 2.6 and have a bunch of print statments in my long program. How can I replace them all with my custom print function, lets call it scribble(). Because if I just search and replace print with scribble( there is no closing parentesis. I think regular expressions is how, but I have experimented with them for a day or so and I can't seem to get it to work.

我使用的是python2.6，在我的长程序中有一堆print语句。如何用我的自定义打印函数替换它们，让我们称其为scribble()。因为如果我只是搜索并用scribble替换print (没有结束的父句。我认为正则表达式就是这样，但我已经用了一天左右的时间来试验它，我似乎不能让它工作。
