Chapter 2-2 calculation of piecewise function [1]

This topic requires the calculation of the following piecewise functions f(x) Value ：

Input format :

The input gives the real number in one line x.

Output format :

Press in a line “f(x) = result” Format output , among x And result Keep one decimal place

Correct code ：

s=float(input())
if s==0:
    print("f(0.0) = 0.0")
else:
    print("f(%.1f) = %.1f"%(s,1/s))

Previous error reporting , Not 0 return （ The last test point can't pass ）

s=int(input())
if s==0:
    print("f(0.0) = 0.0")
else:
    print("f(%.1f) = %.1f"%(s,1/s))

Found to be s The type of was defined incorrectly at first
