import sys
import contextlib
import io

class ConsoleReader(io.StringIO):
    def __init__(self, stream):
        super().__init__()
        self.stream = stream
        
    def enable(self):
        sys.stdout = self
        
    def disable(self):
        sys.stdout = self.stream
        
    def get_last_line(self):
        return self.getvalue().split("\n")[-2]
        
reader = ConsoleReader(sys.stdout)
reader.enable()

print("This message was intercepted")
print("So was this one")
print("hello there")

reader.disable()

print(reader.getvalue()) # Prints the entire buffer
print(reader.get_last_line()) # Custom method to grab the last line in the buffer
