How can I fix this: TypeError: unsupported operand type(s) for /: 'tuple' and 'float'?

Question

I am trying to use the row values to get the C_vel values.

The code:

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

The error message:

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

You can not do mathematical operations on tuples. Using numpy you could convert the tuple to an array first. Mathematical operations can be performed on numpy arrays.

    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
