b=[5, 3, 12, 5, 14]
x=b[0]
b.remove(b[0])
b.insert(len(b), x)
print(b)

I think shortest and accurate

# Shifting Each List Element One Step Left or Right in List
def left():
key=a[0]
for i in range(1, size):
a[i-1]=a[i]
a[size-1]=key
print("List after changes", a)
def right():
key=a[size-1]
for i in range(size-2, -1, -1):
a[i+1]=a[i]
a[0]=key
print("List after changes", a)

# __main__

a=[]
size=int(input("Enter your size: "))
for i in range(size):
val=int(input("Enter value in a: "))
a.append(val)
print()
print("Original list is: ", a)
while True:
key=int(input("Press 1 for Left shifting of element\nPress 2 for Right shifting of element\nEnter your choice: "))
if key==1:
left()
elif key==2:
right()
else:
print("You are out of loop")
break



sir main chahta hu ke emse jb main left function ko call kru tb ye original list ko base bana kr interchange kre na ke right function call krne pr jo list aaya hai usko base bana kar

Thank you so much sir,
For making us fall in love with coding 😊

4:07 a= list(map(int, input("give numbers").split()))
This is a better way i guess

[Art_mood]

Is it right sir???
lst=[ ]
size=int(input("enter size of list: "))
for i in range(size):
x=int(input("enter elemnt: "))
lst.append(x)
a=lst[0]
lst.remove(lst[0])
lst.append(a)
print("your left shifted list: ", lst)

#And for right shift
lst=[ ]
size=int(input("enter size of list: "))
for i in range(size):
x=int(input("enter elemnt: "))
lst.append(x)
A=lst[size-1]
lst.remove(lst[size-1])
lst.insert(0, A)
print("your right sifted list: ", lst)

Great video, keep up the incredible work! :)

Hello sir I have just come in Class XII. Sir there is playlist of yours of 106 videos. Computer Science with Python Class XII Sumita Arora. Can I follow fully that for my Class XII cbse board exam 2022 ?
Is that complete ? (as no reduction now for 2022 board exam students)
It would be nice if you can reply once :)

[sanjaybhagat]

Sir in this code why can't we replace a[size-1]=key with a.append(key)? like the results are differing

[keshav_Jl]

Sir, when will 12th online batch for session 2022-23 launch????

[abhi_piitian]

who come after live class😇
All the best😍😍

@codeitup Sir I do have my program. Please verify that is it right or wrong
For left shifting :-

a=[]
size=int(input("Enter size="))
for i in range(size):
val=int(input("Enter value="))
a.append(val)
b=[]
for i in range(size-1):
b.append(a[i+1])
b.append(a[0])
print("Original list is=", a)
print("Changed list is=", b)

For right shifting :-

a=[]
size=int(input("Enter size="))
for i in range(size):
val=int(input("Enter value="))
a.append(val)
b=[]
for i in range(size):
b.append(a[i-1])
print("Original list is=", a)
print("Changed list is=", b)

[Deepaksharma-jvcg]

Sir, if size=5
Then my output for a[3] & a[4] are coming same.
What am i doing wrong?
I saw everything is same...

[ayushgupta]

thank god in intro he didnt said
chaliye shuru karte hai
😂😂

[nainagupta]

b=a[0]
for i in range(size-1)
a[i]=a[i+1] sir hum ese condition nh kar sakte is case me.???
