Python数学计算

Question

PCD = int(raw_input("What is PCD? ")) 


QOH = int(raw_input("Quantity of holes? ")) 


print "radius: ", 
Radius = float(PCD)/2 
print Radius 


AOS = float(360)/QOH 
print "Angle of Seperation: ", 
print AOS 

import math as M 
def Y_value_1st(a, B): 
    a*round(M.degrees(M.sin(B))) 

print Y_value_1st(Radius, AOS) 

这打印没有，而不是预期的答案，任何人都可以帮忙吗？ 我是python新手

Answer 1

你应该在函数内返回值;

def Y_value_1st(a, B): 
    return a*round(M.degrees(M.sin(B)))
