Split string if uppercase letter is preceded and followed by one lowercase letter - Python

Question

Is there any way to split the string if it contains an uppercase letter but not the first letter? For example, given "RegularExpression" I would like to obtain "Regular Expression". I tried the following regex to solve it: re.sub("[a-z]{1}[A-Z][a-z]{1}", " ","regularExpress") But this deletes the matching pattern: regular press Should I prefer the regex solution or is there any other solution to it? Select the correct answer from above options

Answer 1

You can do this by using the following code: import re s = "RegularExpression" re.sub(r"([A-Z][a-z]+)([A-Z][a-z]+)", r"\1 \2", s) which means "put a space between first match group and second match group", where match groups are the cap followed by one or more non-caps.
