#105111 — from a module return a class

Hello:

Working with python 2.7.

I have a module promptUser_PWord  that will prompt a user for their user name and pword.  Works fine stand alone.
I also have a module, genXLS that does a bunch of processing it has worked fine for months.  And a class Unamepword define as follows:
class Unamepword:
    ## 
    ## class to hold user name and pWord for Database
    uName = None
    pWord = None
    def __init__(self, uStr, pStr):
        self.uName = uStr
        self.pWord = pStr

There are scenarios where running genXLS requires the user to be prompted for their user name and password.

The final line of promptUser_PWord are:
    user_pword =  Unamepword(dbUser, pWord)
    return user_pword


And in genXLS I have  
    ##  prompt the user for a User name a& pWord
    user_pword = promptUser_PWord()   

I get the error 
  File "H:\dev\eclipse\workspace\genXls\src\genXls\promptUser_PWord.py", line 58
    return user_pword
SyntaxError: 'return' outside function


Here is my complete newbee question:
   How do I stich these pieces together so the user will be prompted and the values (contained in the class Unamepword) will be passed back to genXLS ?

Many thanks for your attention to this matter.

KD

Just… define a function (SyntaxError: 'return' outside function).


> The final line of promptUser_PWord become:

user_pword =  Unamepword(dbUser, pWord)
def get_user_pword():
     return user_pword

and call get_user_pword() from within genXLS:

user_pword = promptUser_PWord.get_user_pword()

AFAIU It looks to be the module…

If it were a module, it wouldn't be callable.  It has to be a function
or a class.

My suspicion is the the OP misunderstands how modules work. He is assuming that he can return a value from them. But without the source, who knows??? I think John has the same suspicion as me.

yep OP is not sure how the pieces go together.
source code for promptUser_PWord has been posted.

thanks for your attention to this matter.

<snip>

So promptUser_PWord is a module?  Well, I'm confused.  You gave us this
bit of code:

    user_pword = promptUser_PWord()   

But that can't work if promptUser_PWord is a module; modules aren't
callable.  promptUser_PWord() has to be a function or a class.

Good point; I hadn't thought of that.

true I get the following:  
  File "H:\dev\eclipse\workspace\genXls\src\genXls\genXlswPrompt.py", line 11, in <module>
    import promptUser_PWord
  File "H:\dev\eclipse\workspace\genXls\src\genXls\promptUser_PWord.py", line 58
    return user_pword
SyntaxError: 'return' outside function

so what I get from the various postings is promptUser_PWord must be
converted to a class.  True?
