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

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:)

[@libinvarghese2886]

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

[@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 🙏

[@rajathilak3083]

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

1st thank u for ur video its simple nd easy to understand can you make a factorial program using while loop

[@AmulsAcademy]

This may help you: num = int(input("enter the number: ")) res = 1 i = 1 while i

[@infinity4037]

Your explanation is awesome.

[@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

[@soumyasinha4183]

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

[@AmulsAcademy]

Yes You can :)

[@gajjadatinku5700]

Why zero is taken range function, in this program, how it is used.

[@shafeeqahmed7019]

Mam what if n=0 in this case?

[@manasibhoir3988]

Very good explanation 👍👌

[@AmulsAcademy]

Thank you :)

[@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 :)

[@s2613]

The Best

[@mdfaizan2152]

it is simple bt i was unable to understand this clearly for i in range(number,0,-1): but instead of ths i used for i in range(1,number+1):

[@AmulsAcademy]

for i in range(number,0,-1): Here i value will be in descending order. if number is 5 then , i value will be 5 4 3 2 1 for i in range(1,number+1): here i value will be in ascending order starting from 1. if number is 5 then i value will be 1 2 3 4 5 :)

[@SupGhostly]

the goal is to count down from n. So range (n, 0, -1) means: start at the n value ( n =5 ) go to 0, from the starting point of n value - go down by 1 ( thus -1)

[@diagonalgaming1704]

why is result=1?

[@rafaykhattak4470]

thank u

[@aj0035]

Thank You Honestly ❤

[@vijaykavuri]

I am able to get the program to display the answer, however I need it to also display the actual calculation, for example if the user enters 4 I need it to display as: 4! = 1 x 2 x 3 x 4 = 24 any help on how to add this in to the code?? Thanks in advance!

[@aniljain5094]

Can u make this program using while loop.

[@JonnyGall]

n = int(input("Enter the number: ")) result = 1 while i > 0: result = result * i i = i - 1 print("Factorial of",n,"is",result)

[@santhosh3374]

can't it be 1x2x3x4x5? or only 5x4x3x2x1

[@AmulsAcademy]

Factorial of a positive integer n is the product of all positive integer less than equal to n. 1x2x3x4x5 = 120 5x4x3x2x1 = 120 the way of arranging is different thats it:) I think we write in decreasing order because of the formula. n! = n*(n-1)! :)

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.
