Is there such a function in python string.remove?

Question

C# - String.Remove Ex.

int j = 4;
string pages = "/.././ewcwe/";
pages = pages.Remove(j, 2);
// pages = "/../ewcwe/";
// delete ./

sorry, **./** -> ./

actually, you can probably find your answer here: http://stackoverflow.com/questions/3559559/how-to-delete-a-character-from-a-string-using-python — JMax, Jun 06 '12 at 07:14
What does the `2` mean? You seem to be removing 6 characters here — John La Rooy, Jun 06 '12 at 07:20

Strings are immutable, so you need to extract the parts you want and create a new string from them:

s = pages[:4] + pages[10:]

Alternatively you can overwrite the existing string (as pointed out in the comment below):

pages = pages[:4] + pages[10:]

I don't know C# at all, but the example is `pages = pages.Remove(4, 2)`, in which `pages.Remove` appears to be returning its result rather than modifying `pages` as a side effect. So the immutability of strings appears to be irrelevant. – Ben Jun 06 '12 at 07:20

You can write your own metod.

>>>s="vivek"
>>> def rep(s,st,ed):
...  return s[:st]+s[ed:]
...
>>> rep(s,2,3)
'viv'

No strings don't have such a method

However if you use a bytearray it's easy to remove a slice

pages = bytearray(pages)
del pages[4:10]

Possibly what you are trying to achieve could be done better with a regular expression

a regular expression to remove 2 characters at a fixed position ? come on ! – Adrien Plisson Jun 06 '12 at 07:25
@AdrienPlisson To be fair, the OP did not specify any context. There might well be justification for using regexps. – msvalkon Jun 06 '12 at 07:27
@msvalkon then i would suggest considering a LALR(1) parser. hey, the OP did not speocify any context ! – Adrien Plisson Jun 06 '12 at 07:30
@AdrienPlisson, I can't even imagine how you realised that the question was limited to removing 2 characters at a fixed position. – John La Rooy Jun 06 '12 at 07:33

Simply No

need to use Regular Expressions for faster performance
