Question

program to print the factorial of a number within a range in python​

Answer 1

Answer:

See this example:

num = int(input("Enter a number: "))

factorial = 1.

if num < 0:

print("Sorry, factorial does not exist for negative numbers")

elif num == 0:

print("The factorial of 0 is 1")

else:

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

How do you print the range of a number in Python?

Convert range() to List. If you execute print( type( range(10) ) ) you will get <class 'range'> as output. Python range() function doesn't return a list type. It returns a range object, i.e., sequence object of type range, So as a result, we get an immutable sequence object of integers.

How do you find the factorial of a number using a while loop in Python?

Using While Loop

num = int(input("enter a number: "))

fac = 1.

i = 1.

while i <= num:

fac = fac * i.

i = i + 1.

print("factorial of ", num, " is ", fac)

$\huge \purple{ \underline{ \boxed{ \red{ \mathbb{ANSWER : }}}}}$

$\red{ \textsf{n=int(input("Enter number to find factorial : "))}}$

$\red{ \textsf{fact=1}}$

$\red{ \textsf{for i in range(1,n+1):}}$

$\red{ \textsf{ \: \: \: \: fact=fact*i}}$

$\red{ \textsf{print("Factorial of ",n,"is",fact)}}$

$\large\orange{ \textsf{for}}$

for is the keyword in python which is used to form a loop whose definite length is known , it does not takes the last value . For example , the above loop will run till the number 'n' entered by the user and not till 'n+1' .

$\large\orange{ \textsf{print}}$

print is the keyword in python programming language . It print anything which is written within it .

$\large\orange{ \textsf{input}}$

input takes the input from the user in the form of string .

$\large\orange{ \textsf{int}}$

int converts the input into integer form .
