I don't know what your end character is, but what about something like
postString = inputString.split("\n",2)[2]
The end character might need to be escaped, but that is what I would start with.
x="""version 1.006992[-4.32063, -9.1198, -106.59][0.00064, 0.99993, -0.01210][etc...]abcasdda"""print "\n".join(x.split("\n")[2:])
You can simply do this.
Remove the lines with split:
split
lines = """version 1.006992[-4.32063, -9.1198, -106.59][0.00064, 0.99993, -0.01210][etc...]"""lines = lines.split('\n',2)[-1]
