In this lecture we are configure our idle:

-- we want to previous and next history
-- for that we can configure our idle

just like in cmd suppose you use:
-- ipconfig , start , mkdir, help and many more command
and you want to use previous command or next command:
for that
-- you can use up arrow key and down arrow key

just like that we can configure our idle:

Step 1: open options
step 2: open configure idle
step 3: open keys
step 4: scroll and go to history-previous and history-next
step 5: just click on get new keys for selection
step 6: select up and down arrow key for history-previous and history-next
step 7: click on ok and close the idle

now you can use up and down arrow key for previous and next command

you can use the os module along with the system function to clear the screen import os

def clear_screen():
if os.name == 'posix':
# For Linux and macOS
os.system('clear')
elif os.name == 'nt':
# For Windows
os.system('cls')


You can run this one time.
Next you can start using this command "clear_screen()" to clear the screen as and when needed.

[prasadmvja]

1) Change IDLE configuration Options => Configure IDLE => General tab => Shell preferences => Auto-Squeeze min lines [50] and change 50 to a large count like 1000.
2) Execute command print("\n" * 100) to clear screen

Great Video series !!! Hats off Sir looking forward to more videos on Python. I had the same exact question in my mind when I was learning Python today. Thanks, Sir !!!

[commando]

no.1 work sir no one can compete with your this work.
thanks a

[vidyakumari]

To clear screen
We have to import os module by writing
import os
And then use the in-built function
os.system("cls")
Finally you can keep it as an function cls
Like this-


import os
def cls():
os.system("cls")

thx sir watching from garissa-kenya ...4/7/2019.. 7:15 pm thnks alot ur videos are much better than wat am taught at university

[poorna]

why there are dislikes on this video, he just said what he needs to, are you people expected him to dance or do stunts in the video titled as "python tutorial for beginners", ridiculous people.

[aravindmarri]

ctrl+F6 for new shell or restart the shell...!

[akash]

thanks now i can use this else i was using cmd

[dineshkumargubba]

Try This One.
>>>import subprocess as sp
>>>temp=sp.call('cls', shell=True)

[thebunerikhan]

Ctrl + L also does kind of magic trick, it does not clear the screen but it starts a clean screen.
