Comparing data objects in python ValueError

I wrote a script that retrieves a date from a textfile, converts that to a datetime and checks if the current time is later than the datetime in the file. I wrote the following code for that:

from datetime import datetime

f = open("token.txt", "r")
expiry_date = f.readline()
f.close()

if datetime.now() >= datetime.strptime(expiry_date, "%Y-%m-%d %H:%M:%S.%f"):
    #DO STUFF

However, I get the following error: 

ValueError: unconverted data remains:

Anyone knows where I went wrong and how I can fix this?

The line I want to retrieve from the textfile contains a date formatted like this: 

2020-05-10 19:29:51.503962

When you call readline(), there is a \n appended to the line. strip the newline first.

Please try:

if datetime.now() >= datetime.strptime(expiry_date.strip(), "%Y-%m-%d %H:%M:%S.%f"):
#DO STUFF

It will work.
