Hello,

I have written the below to find factorial of a number.  But the printing part is not great.  For example, instead of 3! is 6, I am getting 3 ! is 6 (with a space before !).

May someone advise how I could fix this?

Thanks

def factorial(n):
total = 1
for i in range(1, n+1):
print(i)
total = total * (i)
return total

num = int(input("Please enter a number "))
print(num,"! is ",factorial(num))

Try this.
``````def factorial(n):
total = 1
for i in range(1, n+1):
print(i)
total = total * (i)
return total

num = int(input('Please enter a number '))
print(f'{num}! is {factorial(num)}')
``````

Thanks All.

Norie, would you explain what does print(f'{...}...{....}') do?

f'.....'  is a format string.
{xxx}   mean variable xxx should be inserted.
{yyy(xxx)}  means the return value of  function yyy with argument xxx should be printed.
