Update clock in program Python without creating new line

Question

I am creating a program for Raspberry Pi where, in Command Line, the program displays the date and time as shown below and I want to add a repeat or update so the date and time are current after the program begins. This code came off a online tutorial and I want to mess around with it and hit a dead end. I am currently learning Python.

#!/usr/bin/python

import time
now = time.strftime("%c")
print "current date and time " + time.strftime("%c")

because you need to delete In [5]:. It was just showing the work from ipython. All you need is datetime.datetime.now() and assign that for variable if you like. — Anton Protopopov

'#!/usr/bin/python import time now = time.strftime("%c") print "current date and time " + time.strftime("%c") import datetime datetime.datetime.now() datetime.datetime.now() datetime.datetime(2015, 12, 11, 11, 0, 37, 518511)' it doesn't update — WickedJDG

see edited answer. It doesn't updated because it's too quick, only microseconds could be displayed — Anton Protopopov

The following code will print time in the same place every second:

import time

while True:
    time.sleep(1.0)
    print("\r" + str(time.time()), end="")

I have tried the code separately and the equal sign in the final line is apparently a syntax error.

Are you using python 2 or 3?

I think this has been answered before here:

You can use a trailing comma to avoid a newline being printed:

print "this should be",
print "on the same line"

You could use datetime module:

import datetime
datetime.datetime.now()

In [5]: datetime.datetime.now()
Out[5]: datetime.datetime(2015, 12, 11, 11, 0, 37, 518511)

EDIT

Try to use following script

#!/usr/bin/python
import datetime
import time

a = datetime.datetime.now()
time.sleep(1)
b = datetime.datetime.now()
print(b-a)

Would that update the time repeatedly until program is closed?

Anton Protopopov Over a year ago

Of course. You could try that several times in python console and will see the results

Thank you. This helps very much.

I have hit a slight problem. It keeps saying syntax error for line 3. Not sure if that is just me.

@J.Gill could you post that line and edit question for that?
