Python Programming Exercises (i)

Learning, are from the book to find some of the programming of small exercises.

1, write a program, he takes the radius of the sphere (floating point) as input, and output the sphere diameter, circumference length, surface area, volume.

defBall (): whileTrue:Try: P= 3.14R= Float (Input ("Please enter sphere radius:"))            ifR <=0:Print("the sphere radius of the input cannot be less than 0! ")            Else:                Print("the diameter of the sphere is:%.3f"% (r*2))                Print("the circumference length of the sphere is:%.3f"% (2*p*R))Print("the surface area of the sphere is:%.3f"% (4*p* (r**2)))                Print("the volume of the sphere is:%.3f"% ((4/3) *p*pow (r,3)))                 Break        exceptValueError:Print("input Error, please enter a number! ")if __name__=="__main__": Ball ()
