I tried to do this and I get this error, how do I g

CodePudding user response：

Use numpy to convert Temp_ list as a numpy array and replace math.log by np.log

import numpy as np

Temp_ = np.array(Temp_)

Debye_A = 3.3690e-01 - 6.3210e-04*Temp_   (9.1425/Temp_) - (1.3514e-02*np.log(Temp_)) \

To perform mathematical operations on every element of an array, you should use numpy. If you want to do it in a regular Python list, you have to loop or use an explicit mapping / comprehension on the list elements:

    return 3.3690e-01 - 6.3210e-04*t   (9.1425/t) - (1.3514e-02*mt.log(t)) \

Debye_A = [ f(t) for t in Temp_ ]

# or 

Debye_A = list(map(f,Temp_))
