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https://attach.52pojie.cn//forum/201907/02/172459fn8k5vzkekyqeekz.jpg?l，但是不知道怎么结合起来，看了好几本书还是不会弄{:1_906:}。求大佬棒棒忙
下面是py计算粘度的代码：
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:
   a = 3.38095
   b = -15.4952
   c = 33.196
   d = 0.78571
   e = 1.7929
   f = -0.183
if 4.4 <= v100 < 5:
   a = 2.5
   b = -7.2143
   c = 13.812
   d = 0.82143
   e = 1.5679
   f = 0.119
if 5 <= v100 < 6.4:
   a = 0.101
   b = 16.635
   c = -45.469
   d = 0.04985
   e = 9.1613
   f = -18.557
if 6.4 <= v100 < 7:
   a = 3.35714
   b = -23.5643
   c = 78.466
   d = 0.22619
   e = 7.7369
   f = -16.656
if 7 <= v100 < 7.7:
   a = 0.01191
   b = 21.475
   c = -72.87
   d = 0.79762
   e = -0.7321
   f = 14.61
if 7.7 <= v100 < 9:
   a = 0.41858
   b = 16.1558
   c = -56.04
   d = 0.05794
   e = 10.5156
   f = -28.24
if 9 <= v100 < 12:
   a = 0.88779
   b = 7.5527
   c = -16.6
   d = 0.26665
   e = 6.7015
   f = -10.81

if 12 <= v100 < 15:
   a = 0.7672
   b = 10.7972
   c = -38.18
   d = 0.20073
   e = 8.4658
   f = -22.49

if 15 <= v100 < 18:
   a = 0.97305
   b = 5.3135
   c = -2.2
   d = 0.28889
   e = 5.9741
   f = -4.93

if 18 <= v100 < 22:
   a = 0.97256
   b = 5.25
   c = -0.98
   d = 0.24504
   e = 7.416
   f = -16.73

if 22 <= v100 < 28:
   a = 0.91413
   b = 7.4759
   c = -21.82
   d = 0.20323
   e = 9.1267
   f = -34.23

if 28 <= v100 < 40:
   a = 0.87031
   b = 9.7157
   c = -50.77
   d = 0.18411
   e = 10.1015
   f = -46.75

if 40 <= v100 < 55:
   a = 0.84703
   b = 12.6752
   c = -133.31
   d = 0.17029
   e = 11.4866
   f = -80.62

if 55 <= v100 < 70:
   a = 0.85921
   b = 11.1009
   c = -83.19
   d = 0.1713
   e = 11.368
   f = -76.94

if v100 >=70:
   a = 0.83531
   b = 14.6731
   c = -216.246
   d = 0.16841
   e = 11.8493
   f = -96.947

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：

输入 40℃与100℃粘度后计算得出粘度指数

要自定义函数名，然后把控件的动作改为目标函数名——
网上是这样说的，我也用pyqt画的——
就是各种报错 ...

翻了几本书了也没搞懂。网上也没有搜到类似的例子。还是缺乏系统的学习啊

看我的帖子，文字识别那个帖子{:1_918:}
第一个代码是功能代码，第二个代码是画出来的界面代码，第三个代码是结合起来的代码。

把你的功能封装成函数，然后将函数绑定给UI的按键就可以了

搞完这个我就去系统的学习一下
