I wish to replace several characters in my string to only one.
Example, "-", "." and "/" to nothing ""
I did like that:
my_string = my_string.replace("-", "").replace(".", "").replace("/",
"").replace(")", "").replace("(", "")
But I think it's a ugly way.
What's the better way to do it?

The maketrans interface is a bit clunky, but this is what
string.translate is best at:
>>> import string
'-./other'.translate( string.maketrans( '', '' ), '-./' )
'other'
It'd be interesting to see where it falls in the benchmarks, though.
It's worth noting that the interface for translate is quite different
for unicode strings.
Right. Unicode .translate() uses a dictionary for defining the
mapping.
Another approach is to use the re module:
>>> import re
>>> re.sub('[-./()]', '', '-./other')
'other'
