Question

I looked at many of the exisiting nameErrors and undefined variable posts and unfortunately was unable to resolve my issue. I am relatively new to programming and especially Python.

I have a dictionary of dictionaries defined in informcast_data.py:

allLinks = {'Send or Edit Messages': {'link':'/InformaCast/admin?cmd=listMessages',   'page_title': 'Messages: Send or Edit Messages'}

I am importing informacast_data.py to users.py:

from informacast.informacast_data import ICData

I then have a function, verify_links which has the following for statement:

for href_link in hrefs:
    if href_link.find(ICData.allLinks['page_title']['link'])!=-1:
        self.logger.debug("verify_links found=True for " + str(href_link))
        found=True

If I leave quotes around page_title I get a keyError and I was told to remove the quotes as it is a variable not a string, I get the nameError when I remove the quotes and I am not sure how to proceed.

below is the full traceback:

Traceback (most recent call last):
  File "C:\Users\jesse.sole\Jesse_Workspace\trunk\src\informacast\tests\users.py", line 17, in test_appadmin_role
    self.verify_role("appAdmin")
  File "C:\Users\jesse.sole\Jesse_Workspace\trunk\src\informacast\tests\users.py", line 78, in verify_role
    self.verify_links(sel, roleName)
  File "C:\Users\jesse.sole\Jesse_Workspace\trunk\src\informacast\tests\users.py", line 104, in verify_links
    if href_link.find(ICData.allLinks[page_title]['link'])!=-1:
NameError: global name 'page_title' is not defined

Thank you in advance for any assistance.

allLinks is a nested dictionary. The top level has no page_title key, so that’s why you get a key error:

>>> allLinks = {'Send or Edit Messages': {'link':'/InformaCast/admin?cmd=listMessages',   'page_title': 'Messages: Send or Edit Messages'}}
>>> allLinks['page_title']                                                                                                      
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'page_title'

There is such a key in the nested dictionary though:

>>> allLinks['Send or Edit Messages']['page_title']
'Messages: Send or Edit Messages'

I think you want to define a variable page_title that has the value 'Send or Edit Messages':

>>> page_title = 'Send or Edit Messages'
>>> allLinks[page_title]['link']
'/InformaCast/admin?cmd=listMessages'

If you loop over the keys in allLinks that would work:

for href_link in hrefs:
    for page_title in ICData.allLinks:
        if href_link.find(ICData.allLinks[page_title]['link'])!=-1:
            self.logger.debug("verify_links found=True for " + str(href_link))
            found=True
