Hi, if I have a string '\\303\\266', how can I convert it to '\303\266'
in a general way?
It's not clear what you mean.
Do you mean you have a string '\\303\\266', that is:
backslash backslash three zero three backslash backslash two six six
If so, then the simplest way is:
s = r'\\303\\266' # note the raw string
len(s)
10
print s
\\303\\266
print s.replace('\\\\', '\\')
\303\266
Another possibility:
s = '\\303\\266' # this is not a raw string
len(s)
8
print s
\303\266
So s is:
backslash three zero three backslash two six six
and you don't need to do any more.
Well, I need the string itself to become '\303\266', not to print
that way. In other words, when I do 'print s', it should display
unicode characters if my term is set to show them, instead of
showing \303\266.
The problem I'm running into is that I'm connecting with pygresql to a
postgres database and when I get fields that are of 'char' type, I get
them in unicode, but when I get fields of 'byte' type, I get the text
with quoted slashes, e.g. '\303' becomes '\\303' and so on.
Is pygresql quoting the backslash, or do you just think it is quoting the
backslashes? How do you know? E.g. if you have '\\303', what is the
length of that? 4 or 5?
Length is 4, and I need it to be length of 1. E.g.:
>>> s = '\303'
>>> s
'\xc3'
>>> x = '\\303'
>>> x
'\\303'
>>> len(x)
4
>>> len(s)
1
What I get from pygresql is x, what I need is s. Either by asking
pygresql to do this or convert it afterwards. I can't do
replace('\\303', '\303') because it can be any unicode character.
