who installed python 3 we should replace python to python3

No need for that.

Some system have python 2.x and python 3.x installed. Where python command points to python2.x binary. Hence python3 is like playing safe in such situation.

This comand 'python manage.py start app APPNAME' will not work.
It should be like this 'python manage.py startapp APPNAME'

python manage.py startapp APPNAME

i think it should be: python manage.py startapp APPNAME and the create venv command should be using python3 for python version 3: python3 -m venv ./venv

if u have only python3 installed u can write python only python3 is basically needed to be written for machines running python 2.x and python 3.x

This is all great but I highly recommend using pipenv for handling your virtual environment. great tool.❤️

who installed python 3 we should replace python to python3

If you don't want to you python2 (or not inside a virtual env), you can change you bashrc file making a alias so python = python 3. This works for linux based systems.

Place this into ~/.bashrc or ~/.bash_aliases file
alias python=python3
After adding the above in the file, run source ~/.bashrc or source ~/.bash_aliases.

It's actually python only. On windows python on CLI works as python but on Mac and Linux it is installed as python3.

So i tried to learn django today, and my PC has latest version of python and django (3.2.3) and when i have typed the "django-admin startproject (My project name) it is showing an error even though my file path is also in a proper order. Can any one help me with this.

• pip freeze
• pip freeze > requirements.txt
• pip install -r requirements.txt

Working from the console with Python:

python manage.py shell

Create new object

from APPNAME.models import CLASSNAME

CLASSNAME.objects.create(key_1 = value_1, key_2 = value_2, key_n = value_n)

Can you do one for python 3?
