python3: removing several chars from a string with a long chain of .replace().replace().replace()
by tgwizard in Programming Languages

I found this example on stack overflow. I understand it, but seems like a bit much for such a simple method concept... removing several chars from a string.

import string
exclude = set(string.punctuation)
s = '.join(ch for ch in s if ch not in exclude)

is there a builtin string method in python 3.1 to do something to the tune of:

s = "a,b,c,d,e,f,g,h,i"

Regex.Replace, String.Replace or StringBuilder.Replace which is the fastest?
by rainy in Programming Languages

I need to replace all System.Environment.Newline(s) in the string returned by my function with System.Environment.Newline + (as I am trying to apply indenting) and I need to do this several times.

My question is which one is the most efficient way to do this?

I know that StringBuilder is faster than String.Replace but

Regex: Replace WITH REPEATED strings , not “replace repeat”
by amelim in Programming Languages

Could we replace a matched pattern with a REPEATED pattern USING regular expression?

For example :
the target string is "abc2:4def" , what I want is abc2222def, that means the "4" is a repeater in the target string and I want to compose my string back to "uncompressed" format.

I could think of the back reference in sed,

sed '

by Mike Bakalov in Programming Languages

I have a string that looks like the following:

"01/11/2012 (Last, First) - Notes,02/11/2012 (Last, First) - More Notes,03/11/2012 (Last, First) - Even More Notes,09/12/2012 (Last, First) - You get the idea"

How to replace all characters in a string using JavaScript for this specific case: replace . by _
by Jimmy G. in Javascript

The following statement in JavaScript works as expected:

var s1 = s2.replace(/ /gi, '_'); //replace all spaces by the character _

However, to replace all occurrences of the character . by the character _, I have:

var s1 = s2.replace(/./gi, '_');

But the result is a string entirely filled with the character _

How to replace broken German Umlauts with MySQL REPLACE function?
by Chook2330 in Development Tools & Services

(I accidentially asked this question first on DBA but found out in the FAQ to ask SQL questions here on SO instead)

I'm trying to "repair" a MySQL database (UTF-8 collation) that was imported from an encoding-broken SQL text file.

I.e. the German umlauts are broken inside the database. What should read e.g. "ü" is displayed as "ü".

Since I'm aware of the

RegEx.Replace to Replace Whole Words and Skip when Part of the Word
by patheems in Programming Languages

I am using regex to replace certain keywords from a string (or Stringbuilder) with the ones that I choose. However, I fail to build a valid regex pattern to replace only whole words.

For example, if I have InputString = "fox foxy" and want to replace "fox" with "dog" it the output would be "dog dogy".

What is the valid RegEx pattern to take only "fox" and leave "foxy"?
