Python error: keyword can't be an expression. print value

Question

I am making a game that has a fake loading screen in the beginning. I am trying to make a gradual elipsys that adds a period every second until there are 3 periods. this is the code I put in:

    def intro2():
        print('Loading CapsuleCorp computer'=end)
        time.sleep(1)
        print ('.'=end)
        time.sleep(1)
        print ('.')
        time.sleep(3)
        print ('Welcome to the CapsuleCorp main computer.')
        time.sleep(1)
        print ('Due to new security issues, we have added a new security system.')
        print ('If you are an employee, we teach you these maditoraly.')
        time.sleep(1)
        print ('we wipe your mind as an ex-enployee')

Then, after running, I get this error:

    keyword can't be an expression

and it highlights this:

    print**(**'Loading CapsuleCorp computer'=end)

You were going to put `time.sleep(2)` into a `print()` call, so you tried to accomplish that by adding `=end` to it? And the purpose was to "do" an ellipsis? I suggest you start [here](https://docs.python.org/3.4/tutorial/). — TigerhawkT3, May 14 '15 at 00:42
I am sorry for my wording. I wanted the `time.sleep(2)` function to be on the line below it, and then another print after that that prints a '.', and then to repeat it one more time. — Shiloh Janowick, May 14 '15 at 00:46
Can you edit your question to include what you're trying to do, what kind of attempts you've made, and what you expect to see? We can't extrapolate that from a single poorly-formed `print()` call. — TigerhawkT3, May 14 '15 at 00:49
Also take a look at [this](http://stackoverflow.com/help/how-to-ask). — TigerhawkT3, May 14 '15 at 00:50

This will fix it:

print('Loading CapsuleCorp computer=', end)

Based on your additional comment below, you may be looking for this:

print('Loading CapsuleCorp computer', end='')

I tried it, and I got this: NameError: global name 'end' is not defined – Shiloh Janowick May 14 '15 at 00:33
Until you tell us what you expected to see, all we can do is guess. – TigerhawkT3 May 14 '15 at 00:36
In this context, Python is expecting "end" to be a variable that contains a value. – michaelfavor May 14 '15 at 00:36
I am wanting it to use the `time.sleep()` function, but for it not to start a new line. – Shiloh Janowick May 14 '15 at 00:44
It's possible that you were looking for `end=''`, but, like this answer, that's just a guess. – TigerhawkT3 May 14 '15 at 00:46
Did you test it? Is it doing what you want? Because I don't think it will. – TigerhawkT3 May 14 '15 at 01:10
I tested it. It works. It did what I wanted. Thank you. – Shiloh Janowick May 14 '15 at 01:14
And it's printing with delays where you expect them to be? – TigerhawkT3 May 14 '15 at 01:17
I'm not sure how that's possible, because I've tried it from the interactive interpreter and from a saved script, and without the `sys.stdout.flush()` calls it waits 5 seconds and then dumps all the `print()` calls at once. – TigerhawkT3 May 14 '15 at 01:24
Oh, I just tested it outside of IDLE. when I tested it outside of idle, It did what you said it would do. – Shiloh Janowick May 14 '15 at 01:44
