input_number=int(input('Enter any number between 1 to 10:')) #entering the input numbers
display="" #initialising display
if input_number<1 or input_number>10: #checking if else statement
display="\nE error. number must be between 1 to 10."
else:
#valid
display="\n the Roman numeral version of "
if input_number==1: #checking elif statement
display += format(input_number) + " is I" #assigning roman numbers to diplay
elif input_number==2:
display += format(input_number) + " is II"
elif input_number==3:
display += format(input_number) + " is III"
elif input_number==4:
display += format(input_number) + " is IV"
elif input_number==5:
display += format(input_number) + " is V"
elif input_number==6:
display += format(input_number) + " is VI"
elif input_number==7:
display += format(input_number) + " is VII"
elif input_number==8:
display += format(input_number) + " is VIII"
elif input_number==9:
display += format(input_number) + " is IX"
elif input_number==10:
display += format(input_number) + " is X"
print(display,'\n') #print display
