replace %(word) in a string

[Maxime Biais]

Hello,

I heard that is possible to replace %(word) in a string with a dictionary
containing { "word" : "replaced word" } with a function or a builtin from
the python library.

For example with the string: "hello, %(word1) %(word2) !" and the
dictionary: {"word1" : "python", "word2" : "lovers"} the final string
would be: "hello python lovers"

For the moment i use this code but i want something more pythonic:

str:
var_dic:

for i in var_dic:
myre = re.compile("(.*)(\%\(%s\))(.*)" % i, re.IGNORECASE)
re_res = myre.match(str)
if re_res:
str = re_res.group(1) + var_dic + re_res.group(3)

You are almost there.

"hello, %(word1)s %(word2)s !" % {"word1":"python", "word2":"lovers"}
