How to replace several different characters in text file using asterisk in python?

[yaron148]

I try to delete from text file those characters '{a}' '{b}' ... and so on (i have 250 curly braces in the text file) using this code:

# -*- coding: cp1255 -*-
import sys,codecs,string
 
reload(sys)
sys.setdefaultencoding('utf8')
root = r"G:\desktop\y\test2.txt"
x = open(root)
s=x.read().replace('{*}','').replace('-','')
x.close()
x=open(root,"w")
x.write(s)
x.close

because the letters change in every curly brackets i used asterisk in the,

but after i run this code nothing change in the text file:

>>> ================================ RESTART ================================
>>>
>>>

It's not clear what you are trying to do.

Can you provide a minimum example of you filterfile (test2.txt), and and what you expect as output?

How about using "re.sub"?
Here is an example to delete characters '{a}' '{b}' '-'

import re
text = "aaaaaa{a}-bbbbbbb{b}-ccccc{c}-dddddd{d}."
text_mod = re.sub('\{[a-b]\}','',text).replace('-','')
print (text_mod)
 

result :aaaaaabbbbbbbccccc{c}dddddd{d}.
