来自未在python中导入的模块的功能

Question

Good evenning guys,

I ve got that weird behavior. Any help would be appreciated.

Here is a function from a module called tankython, calling a function from a module called usual. However, it looks like Python refuses to recognize the function. Here is the code

#tankython.py

from usual import * 
from get_data import *
from settings import *
from actif_class import * 

def tanking(list_spreads,settings):    
####    Tanking    ####  
    fenetre = settings.fenetre    
    list_spread_exit,list_spread_temp= [],[]

    ii= 0       
    for spread in list_spreads : 
        avc = ii * 100/float(len(list_spreads))
        print "Be patient. Tanking in progress..." , avc,"%"
        info = tankython (list_spreads,fenetre,ii) 
        list_spread_temp.append(info)
        ii = ii + 1
    list_spread_exit = check_list(list_spread_temp)

    return list_spread_exit

#usual.py

def check_list(list_entry):
    i = 0
    while i < len(list_entry):
        if list_entry[i] == 0 :
            list_entry.pop(i)
        else : 
            i = i+ 1
    return list_entry

Here is the error message which I found really weird as I asked Py to import everything from usual.py:

File "tankython.py", line 77, in tanking
  list_spread_exit = check_list(list_spread_temp)

NameError: global name 'check_list' is not defined

One last thing: eventually, if I put the function in tankython module, then Py accepts to goes through the entire process. However I really would like to know if there is anything I am doing wrong here.

Cheers guys

Answer 1

Try to put file tankython.py and usual.py in the same folder and use the

from usual import check_list

instead of

from usual import *

May help. Or you can try:

import usual

Then change code like:

usual.check_list()

And

from module import *

is not a good way to import something if two packages have the same name functions.

Answer 2

I find another solution, although it is not the most elegan one, especially because it did not explain what went wrong. However, I renamed the entire module usual by f_usual and it is working perfectly fine.

Thanks for your help
