当你把2个数字放进去的时候,我试着打印出应该做的答案。在我运行之后,我得到了NameError
。是。我确实尝试了ring_size = areaOfRing()
,ring_size = areaOfRing(r_out, r_in)
给了我两个错误。
(注意,重新启动程序后,它开始使用@ Martijn的帮助。)

您没有正确调用您的功能,请执行以下操作:
ring_size = areaOfRing(r_out, r_in)
答案 1 :(得分:0)
调用函数时需要提供arguments
。
import math
# ring size calculating function
def areaOfRing(r_out, r_in):
r_outs = (r_out**2)*math.pi
r_ins = (r_in**2)*math.pi
ring_size = r_outs - r_ins
return ring_size
r_out = int(input("Insert rings outside raadius: "))
r_in = int(input("Insert rings inner raadius: "))
ring_size = areaOfRing(r_out, r_in)
print('Ring size is = ',ring_size)
