Question

Write program to
find the factorial of a given number
Input N=5 then Output
5*4*3*2*1 =120​

Answer 1

Answer:

n=int(input("enter no."))

f=1

for i in range(1,n+1):

f=f*i

print("factorial of number is",f)

Answer 2

The given python program iteratively finds the factorial of the number given as input.

Explanation:

• The given snippet firstly takes the number as input whose factorial is required.
• Then the variable f is declared and initialized to 1.
• Then the factorial is found out by iteratively multiplying the numbers.
• Finally, after the iteration is completed, the final result is stored in the variable f.
• The result is then displayed using the print command.

n = int ( input ( " enter no. " ) )

$f=1$

$s=" "$

$for \hspace{0.2 cm}i \hspace{0.2 cm}in \hspace{0.2 cm}range(1, n+1):$

        $\hspace{0.5 cm}$ $s + = str\hspace{0.02 cm}(i)+"*"$

        $\hspace{0.5 cm}$ $f=f \cdot i$

$s+="="$

$print(s,f)$
