Why this script doesn't give an output?

Question

from math import pi
def area(r):
a=float(pi*float(r)*float(r))
return a
x=input('enter the radius : ')
y=input('enter the decimal place(1 to 5): ')
z=area(x)
if y==1:
print('area of circle is ')
w=round(z,1)
print(w)
if y==2:
print('area of circle is ')
w=round(z,2)
print(w)
if y==3:
print('area of circle is ')
w=round(z,3)
print(w)
if y==4:
print('area of circle is ')
w=round(z,4)
print(w)
if y==5:
print('area of circle is ')
w=round(z,5)
print(w)

Answer 1

y=int(input('enter the decimal place(1 to 5): '))

Answer 2

Because y is a string so it fails to match your integers

Answer 3

You can simplify the printing part by checking validity of the decimal places input with "if" as follows:

z=area(x)
if y in range(1, 6):
print('Area of circle is: ', round(z, y))
else:
print('You entered invalid decimal places')
