for example:
T h e t e x t i s w h a t I w a n t t o r e p l a c e
I want the result like this:
The text is what I want to replace
I tried that with shell, sed,
echo 'T h e t e x t i s W h a t I w a n t r e p l a c e'|sed -r "s/(([a-zA-Z])\s){1}/\2/g"|sed 's/\ / /g'
it's successfully. but I don't know how to replace this in python. could anybody help me?
If you just want to convert a string that has whitespace between each chars:
>>> import re
>>> re.sub(r'(.) ', r'\1', 'T h e t e x t i s w h a t I w a n t t o r e p l a c e')
'The text is what I want to replace'
Or, if you want to remove all single whitespace and replace whitespaces to just one:
>>> re.sub(r'( ?) +', r'\1', 'A B C D')
'AB C D'
Just for kicks, here is a non-regex solution using string operations:
>>> text = 'T h e t e x t i s w h a t I w a n t t o r e p l a c e'
>>> text.replace(' ' * 3, '\0').replace(' ', '').replace('\0', ' ')
'The text is what I want to replace'
(Per the comment, I changed the _ to \0 (null character).)
'\0' instead of '_'.
Just for fun, two more ways to do it. These both assume there is strictly a space after every character that you want.
>>> s = "T h e t e x t i s w h a t I w a n t t o r e p l a c e "
>>> import re
>>> pat = re.compile(r'(.) ')
>>> ''.join(re.findall(pat, s))
'The text is what I want to replace'
Even easier, using string slicing:
>>> s[::2]
'The text is what I want to replace'
