将模块（func1.py）导入test.py文件后，未定义nameError：name'pd'

Question

import sys
sys.path.append('/Users/name/Documents/pythontemp/functemp/')
In the test.py file:
import pandas as pd
for file in os.listdir('/Users/name/Documents/pythontemp/functemp/'):
    if 'func' not in file:
        continue
    fileN=file.split('.')[0]
    print(fileN)

    Class=__import__(fileN)
    func=getattr(Class,fileN)

    para=func.__code__.co_varnames
    print(para)
    if 'n1' not in para:
        idx=func.__code__.co_argcount
    else:
        idx=para.index('n1')
    print(idx)
    paras=[eval(x) for x in para[:(idx)]]
    #print(paras)
    dict_=dict(zip(para[:idx],paras))
    #print(dict_)

    factor=func(**dict_)
    display(factor)

The nameError is:

 func2 ('a', 'b', 'c', 'result') 3

   ----> 2     a=pd.DataFrame(a)
         3     result=a+b-c
         4     return result

   NameError: name 'pd' is not defined

The func2.py file is:

def func2(a,b,c):
    a=pd.DataFrame(a)
    result=a+b-c
    return result

I have lots of py file like func2.py (eg. func1.py , func3.py ...) in the same file folder. In the test.py , I have imported pd , but func2.py not.

So how to solve it?

Answer 1

The NameError in func2.py is because that file does not know what pd is because you have not imported it in that file. Note that you have correctly imported pandas in the test.py file. Add the following to the top each of the func*.py files that have pd:

import pandas as pd
