Python Programs - Factorial Program Using for loop

[@algo3an]

finally, someone explains it in details. I struggled a lot trying to understand it. Keep up the good work

[@AmulsAcademy]

Thank you :)

[@Ayasir-lo3ir]

it's simple it goes back to for loop when the there is no more list it will return the list

You are THE best python teacher on YT. Thanks from New York!

[@srishtinisha1712]

I came here after watching so many videos which goes over my head.. finally the way you explain in detail clear my concept.. thank you so much 🙏

[@libinvarghese2886]

Thank you ma'am.. this explanation is truly a gem. I was trying to learn this for a week.

[@chidij20]

You are definitely a good teacher 👏🏽👏🏽👏🏽👏🏽I need more classes so I had to follow you

[@chennaramana9893]

I don't know your age but the way you teaching was with full of clarity and even non IT can also learn this python through your teaching but my request make some videos about complex programs of using combinations of if, for , while and also tkinter kindly

[@AmulsAcademy]

Sure:)

[@omkar1592]

Thanks Amulya for this amazing explanation!!!

[@AmulsAcademy]

Pleasure 😊❤️

[@francescowang]

n = 5
result= 1
for i in range(n, 0, -1):
result *= i
print('the factorial of', n, 'is', result)
alternative method:
n = 5
result= 1
for i in range(1, n + 1):
result *= i
print('the factorial of', n, 'is', result)
Why does (n, 0, -1) work the way it does? I find (1, n + 1) slightly easier to understand. It begins at 1, then to stop the loop you do n+1.
Fantastic video btw. Please keep making them. You are brilliant. I just subscribed.

[@AmulsAcademy]

range(n,0,-1) will give output 5 4 3 2 1 😊

[@nevaehortiz8210]

Hey, I love the video and I now understand it better but do you know how to make it so it only gives a factorial of numbers in a set range?? I need it to be between 1 and 25 but I don't know how to get the range set without it running through every single number, thank you for any help :] have a good day

[@raravindh8808]

Thank you mam

[@soumyasinha4183]

Here we can take range as (1,n+1)?

Yes You can :)

[@rafaqathussain7259]

good explanation

[@AmulsAcademy]

Thank you :)

[@neelampandey1718]

3:45 y take stop arg. as 0......it works till " stop-1" so taking it 0 doesn't mean the loop will run till 0-1= -1 ?!?!

[@AmulsAcademy]

No it will works till 1.
we took step as -1 so values will be in the reverse order.
if n=5
then range(n,0,-1)
means range(5,0,-1) = 5 4 3 2 1
0 is excluded.
:)

[@venkataramanabanda8105]

If take n = 0 then what will happens..how works plz tell me...0*1=0

[@rajathilaks]

Hello Amulya,
I have doubt,
num=0
result=1
if i in range(num,0,-1): #(0,0,-1)#i=0
result=result*i #1=1*0=0
print (result) #ans=0#how it get output 1
Can you clarify me above concept for given input as 0
Thanks in advance

[@AmulsAcademy]

if i in range(num,0,-1): #(0,0,-1)#i=0
I think it is not if , you are using for loop.
and when range() starts from 0 and ends 0 it won't take i as 0, actually it won't give any value because end value is exclusive.
So it won't execute for loop body.
it will print the result, that's why you will get result as 1.
if you want result as 1 then you can write like this:
for i in range(num,-1,-1): #(0,-1,-1)#i=0

[@nagaratnacp1718]

Instead of using (n,0,-1)..we can use (1,n+1) ryt mam?

[@AmulsAcademy]

In range function when we use range(n,0,-1) means start is n end is 0.
for example if n=5 range(5,0,-1) = 5,4,3,2,1
But range(1,n+1) is different. Here start is 1 and end is n+1.
for example n=5 range(1,6) = 1,2,3,4,5

[@asiachannel2826]

Really mam your voice is very beautiful like cackoo

[@anuragmu2925]

And when we have to print like 5×4×3×2×1=120 what we have to do

[@s2613]

Why did you take result=1 ?
Could please tell me Amulya

[@AmulsAcademy]

Because to get factorial of number we need to do multiplication.
result is the variable which will hold my final result.
If i take 0 , 0 multiply anything will be 0, that's why i took 1.
value 1 won't change any output, because if you multiply any value with 1 answer remains same
