When I run python manage.py migrate on my Django project, I get the following error:

Traceback (most recent call last):
File "manage.py", line 22, in <module>

File "/home/hari/project/env/local/lib/python2.7/site-     packages/django/core/management/__init__.py", line 363, in execute_from_command_line

I have a user model like below:

class User(AbstractUser):
    place = models.CharField(max_length=64, null=True, blank=True)
    address = models.CharField(max_length=128, null=True, blank=True)

How can I solve this problem?

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

I was preparing for my coding interview, thanks for clarifying this - django.db.migrations.exceptions.InconsistentMigrationHistory in Python is not the simplest one. I just hope that will not emerge anymore

Maybe there are another answers? What django.db.migrations.exceptions.InconsistentMigrationHistory exactly means?. I am just not quite sure it is the best method
