How to replace only integers in a string by a string

Question

My script:

x="the number 1234, today the 909090 of the value of the 90.94"
# by the way the has to be proposed to get the123abd 123the" by a string "ItWasanINT""

re.sub(r'\b\d+(?!\.\d+)\b','ItWasanINT',x)

...Not working

Why don't you document the post-substitution value your code generates, and what you'd like it to generate? — Tony Delroy

You probably want to exclude numbers that are both not preceded by a "number." combo and not followed by a ".number" combo:

re.sub(r'\b(?<!\d\.)\d+(?!.\d)\b','ItWasanINT', x)

Result:

>>> import re
>>> x="the number 1234, today the 909090 of the value of the 90.94"
>>> re.sub(r'\b(?<!\d\.)\d+(?!\.\d)\b','ItWasanINT',x)
'the number ItWasanINT, today the ItWasanINT of the value of the 90.94'
