Printing a string between two characters

I'm writing a python script that will extract specific parts of lines in a text file and print them out. The part of that line is always between two specific characters. For example, I need to print everything between "Ghost: " and "(".

I've tried importing re and using it to search a string for characters, but I failed.

The file looks something like this:

Ghost: john.doe.1 {} ...
Ghost: john.walker.4 {} ...
Ghost: john.johnny.3 {} ...
Ghost: john.craig.6 {} ...
...

I'm expecting something like this:

john.doe.1
john.walker.4
john.johnny.3
john.craig.6

Using regex, you can do:

re.search('((?:[a-z][a-z]+))(\\.)((?:[a-z][a-z]+))(\\.)(\\d+)', text).group()

Output:

john.doe.1
john.walker.4
john.johnny.3
john.craig.6

Logic:

'((?:[a-z][a-z]+))' - looks for word (a-z)
'(\\.)'             - looks for dot
'((?:[a-z][a-z]+))' - looks for word (a-z)
'(\\.)'             - looks for dot
'(\\d+)'            - looks for digit (0-9)

you can use split method and extract the required info 

word="Ghost: john.doe.1 {} ..."
word=word.split(":")[1]
print(word.split()[0])

OUTPUT:

john.doe.1

split the string on whitespace and then print 2nd substring i.e

print(string.split(' ')[1])
