I am trying to replace a word using re.sub in python. The format is
re.sub(pattern, replacement,string)
Lets consider the following snippet of code
sentence = "I want to replce this sentence"
pattern = "replce"
replacement = "replace"
print(re.sub("[\W]{}[\W]".format(pattern), " {} ".format(replacement), sentence))
Would give output
I want to replace this sentence
Now I want to capture the non-alphanumeric characters around the pattern so that I can include them in the replacement as well. In this example, I am forcing spaces around replacement, which should not be the scenario.
For example
sentence = "I want to !replce, this sentence"
pattern = "replce"
replacement = "replace"
print(re.sub("[\W]{}[\W]".format(pattern), " {} ".format(replacement), sentence))
Would give output
I want to replace this sentence
but I want
I want to !replace, this sentence
What is the solution?
