我該如何解決這個問題：TypeError：用於/：'tuple'和'float'的不受支持的操作數類型？

Question

我想使用行值來獲得C_vel值。

代碼：

wb = op.load_workbook('Canopy\Scripts\De Velliers.xlsx') 
ws = wb ['Sheet1']       
for row in ws.rows: 
    for cell in row: 
     print(cell.value) 
     print "----------" 
     C_vel = ws.rows/(A_c * rho) 
     print "C_vel: ", C_vel 

錯誤消息：

TypeError      
Traceback (most recent call last) 
C:\Users\Fraixxer Fraiz\Canopy\scripts\franis 1.py in <module>() 
    26   print(cell.value) 
    27   print "----------" 
---> 28   C_vel = ws.rows/(A_c * rho) 
    29   print "C_vel: ", C_vel 
    30 

TypeError: unsupported operand type(s) for /: 'tuple' and 'float'

您不能在元組做數學運算。使用numpy可以將元組首先轉換爲數組。數學運算可以在numpy數組上進行。

import numpy as np 
    wb = op. load _ workbook ('Canopy\Scripts\De Velliers.xlsx') 
    ws = wb ['Sheet1']        
    for row in ws . rows: 
     for cell in row: 
      print(cell. value) 
      print "----------" 
      C_vel = np.array(ws. rows)/ (A_c * rho) 
      print "C_vel:",C_vel
