自己写了个计算粘度指数的python文件，想做个界面。在pyqt5里面做的效果图 ，但是不知道怎么结合起来，看了好几本书还是不会弄 。求大佬棒棒忙
下面是py计算粘度的代码：
[Python] 纯文本查看 复制代码 import math
v100 = input("100℃运动粘度:")
v100 = float(v100)
v40 = input("40℃运动粘度:")
v40 = float(v40)
if v100 < 3.8:
a = 1.14673
b = 1.7576
c = -0.109
d = 0.84155
e = 1.5521
f = -0.077
if 3.8 <= v100 < 4.4:

def l():
return a * v100 ** 2 + b * v100 + c
def h():
return d * v100 ** 2 + e * v100 + f
def n():
return (math.log(h()) - math.log(v40)) / math.log(v100)
def vi_1():
return (10 ** n() - 1) / 0.0075 + 100
def vi_2():
return ((l() - v40) / (l() - h())) * 100
if vi_1() <= 100:
print(round(vi_2()))
else:
print(round(vi_1()))
然后界面转的py代码：
