insted of telusko learnings it should be telusko blessings

[chessbd]

This programming example is well thought out and kinda refreshing! It helps me to get back to tutorial again!. thanks for your selfless act.

[edisonjoshua]

k = int(input("Enter the number to calculate the factoroial "))

j = 1
for i in range(1, k+1):
j = i * j
print ("The factorial of ", k, "is", j)

[AlankritIndia]

factorial using while loop


def fac(n):
f=1
i=1
while(i<=n):
f=f*i
i+=1
print(f)
fac(6)

I feel sorry for the first time on youtube about forget to like videos. Thank

[BhuveshDhiman]

def fac(n):
if n==0:
return 1

s=1
for i in range(1, n+1):
s=s*i
return s



n=int(input("Enter a no."))
ans=fac(n)
print("Factorial = ", ans)

[shaunakshukla]

n=int(input("enter any no"))
def fact(n):
for i in range(1, n):
n=n*i
print(n, end=" ")
fact(n)
output
enter any no 5
5 10 30 120

Easiest Answer
x = int(input("Enter a Number: "))
result = 1
for i in range(x):
result = result * (x - i)
print(result)

[ritikasharma]

No one can beat you in teaching python thanku ❤️

[sumankumarkarmakar]

def fact(n):
if n < 0:
print('Should be +ve number')
else:
a = 1
for i in range (1, n + 1):
a = a * i
return a


x = int(input('give a number for factorial = '))
result = fact(x)
print('the factorial of ', x, 'is = ', result)

[karthikkeyansmk]

factorial in my way sir!
def facto(num):
e = 1
for i in range(1, num+1):
e *= i
print("factorial of ", num, '! is ', e)
user = int(input("Enter which number factorial you want : "))
facto(5)

[gouripeddipawansreekar]

factorial without functions::

x = int(input("enter a number"))
z=1
while x>0:
z=z*x
x=x-1
print("factorial of x is", z)

[ElyasSAhmad]

z = int(input('enter the number which you waant to find the factorial of it: '))
c = 1
d = 2
for a in range(z-1):
b = c * d
c = b
d +=1
if z <= 1:
print(c)
else:
print(b)

[rameshbanoth]

factorial of a number

def fact(n):
x=n
for i in range(1, n):
x*=(n-i)
return x

result=fact(5)
print(result)

[_a.j_a.y]

def fac(n):
a=[ ]
for i in range(1, n+1):
a.append(i)
import numpy
c=numpy.prod(a)
Print (c)

[mr.KrishnaTalks.]

def multiply (n):
if n<=1:
return 1
return (n * multiply (n-1) )

n = int (input())
res = multiply (n)
print (res)

[MacroNinja]

def fib(n):
if n < 0:
print("Must be a number above zero! ")

a = 0
b = 1

if n == 1:
print(a)

elif n > 1:
print(a)
print(b)

for i in range(2, n):

c = a + b
a = b
b = c
print(c)

fib(-2)

[hozaifashakeel]

my code for finding factorial->
a=int(input("enter the number:"))
def fac(a):
b = 1
for i in range(1, a+1):
b=b*i
print(b)
fac(a)

[Maxmikemusic]

you can also do :
def factorial(n):
if n == 0:
return 1
else:
recurse = factorial(n-1)
result = n * recurse
return result
