How can I load an image dynamically based on radiobutton selection

I am making adding a character selection to a queue accept tool using radiobuttons for the characters.
the character selection is based on object detection using cv2, and I need to make it so whatever character you select affects the file cv2 opens.
This is what I'm using:
def selection():
if select:
screenshot = wincap.get_screenshot()
# Import selection to Vision Class
test=0
test=v.get()
characterSearch = charSearch('./CharacterSelect/' + str(characters[test]+'.jpg'))
print('./CharacterSelect/' + str(characters[test]+'.jpg'))
characterMatch = characterSearch.find(screenshot, .63, 'rectangles')
if len(characterMatch):
charSelect_off()
window.after(500, selection)
#Stores interger values
v = IntVar()
v.set = ()
# Radio button loops for character select
for index in range(len(characters)):
Radiobutton(bottomframe,
compound = TOP,
image = portraits[index],
text = characters[index],
variable = v,
value = index,
).grid(
row = index//5,
column = index%5,
)
This errors saying it can't find the path.
the print however is able to print selection.
So I need to find a way to create a dynamic str with cv2.imread() in order to do this. or another option entirely, like if I can read it from a list of images loaded via tkinter, that would work too as I have a list built, so if i could index that, that would also be more optimal.
Edit:
Adding the error received:

I was able to figure this out when I found this: https://stackoverflow.com/a/48562343/20593304
creating a dynamic path using the string I created.
charVariable=0
charVariable=v.get()
pathtoCharacters = os.path.join(os.getcwd(), "CharacterSearch", str(characters[charVariable]+".jpg"))
characterSearch = charSearch(pathtoCharacters)
which then implements to my class that performs the object detection.

Unable to get element text using Selenium with Chrome

I'm trying to scrape Merriam-Webster's Medical Dictionary for medical terms using Python and Chrome as the Selenium webdriver. So far, this is what I have:
from os import path
from selenium import webdriver
# Adding an ad-blocker to Chrome to speed up page load times
options = webdriver.ChromeOptions()
options.add_extension(path.abspath("ublock-origin.crx"))
# Declaring the Selenium webdriver
driver = webdriver.Chrome(chrome_options = options)
# Fetching the "A" terms as a test set
driver.get("https://www.merriam-webster.com/browse/medical/a")
scraped_words = [] # The list that will hold each word
page_num = 1
while page_num < 55: # There are 54 pages of "A" terms
try:
for i in range(4): # There are 3 columns per page of words
column = "/html/body/div/div/div[5]/div[2]/div[1]/div/div[3]/ul/li[" + str(i) + "]/a"
number_of_words = len(driver.find_elements_by_xpath(column))
for j in range(number_of_words):
word = driver.find_elements_by_xpath(column + "[" + str(j) + "]")
scraped_words.append(word)
driver.find_element_by_class_name("fa-angle-right").click() # Next page
page_num += 1 # Increment page number to keep track of current page
except:
driver.close()
# Write out words to a file
with open("medical_terms.dict", "w") as text_file:
for i in range(len(scraped_words)):
text_file.write(str(scraped_words[i]))
text_file.write("\n")
driver.close()
The above code fetches all the items, as the output of len(scraped_words) is the number expected. However, since I did not specify that I wanted to fetch the text of the elements, I get element identifiers (I think?) instead of text. If I decide to use word = driver.find_elements_by_xpath(column + "[" + str(j) + "]").text in order to specify that I want to get the text of the element, I get the following error:
Traceback (most recent call last):

What is strange to me here is that the only code I change between runs is on line 22 yet the error message points out line 20 instead.
Any help in deciphering what's going on here and what I can do to fix it would be much appreciated! :+)

You just need to create a words list accessing your elements texts, changing:
word = driver.find_elements_by_xpath(column + "[" + str(j) + "]")
to:
word = [i.text for i in driver.find_elements_by_xpath(column + "[" + str(j) + "]")]
Because .find_elements_by_xpath will always return a list, accessing .text directly won't work.

Multiprocessing map unorderable?

I don't understand, even by reading this carefully (https://docs.python.org/3.5/library/multiprocessing.html#module-multiprocessing).
Each chunk is a dict, so it should be sent through map to the builder.
But instead I get that stupid error and the traceback doesn't help. I looked into the code of pool.py but no luck,
and my builder is not involved since its first operation (a control printing) is not even displayed. The builder function seems to be totally ignored (and there is not even a syntax error)
So I conclude this is a problem with map.
In case I would have misunderstood the multiprocessing.map function and that it would first make a chunk, then iterate over it to apply map on each sub sub element, what function of multiprocessing could I use? Apply use only one thread. That would mean I should do this manually?
Please feel free to correct my code and give me some insights. Thanks by advance
Edit: here is the builder function:
def Builder(dictionary,struc=struc):
#def Builder(keys, dictionary=dictionary,struc=struc): #Alternative
#Note, I even tried to use only the keys, passing the dictionary from a global variable but it didn't work
print("Building Tree") #Not even displayed
print("type dictionary"+str(type(dictionary)))

if True:
print("Building")
#for id in keys: #Alternative

for i in range(3):

break
seq=seq[i:-i]
struc.append(seq)
print("Number of frags found {}".format(frags))

WebDriver. Python. I want to store one of the option of drop-down menu by value as text, how to do it?

I want to store one of the option of drop-down menu by value as text. I select random option by next Python script:
#Random select option by value
assignJob = Select(driver.find_element_by_name('job[job_title]'))
jobValue = str(randint(1, 6))
assignJob.select_by_value(jobValue)
HTML code:
<select name="job[job_title]" class="formSelect valid" id="job_job_title">

You could use a CSS selector, to locate that option and ask selenium to return its text.
driver.find_element_by_css_selector("#job_job_title option[value=2]").text
Replace 2 with the variable jobValue for you specific scenario.
EDIT
jobValue is a variable(str), you cannot directly pass a variable in Python.
jobValueSelector = "#job_job_title option[value='%s']" %jobValue
storedJob = driver.find_element_by_css_selector(jobValueSelector).text
print storedJob

The piece of code below is in Ruby.. I think Python and Ruby is almost the same.
select_list = driver.find_element(:id, 'job_job_title')
options = select_list.find_elements(:tag_name, 'option')
index = rand(1..options.count) # Get random number from index 1 to options.count
my_variable = options[index]
Let me try my skill in Python (not tested)! :)
select_list = driver.find_element_by_id("job_job_title")
options = select_list.find_elements_by_tag_name("option")
index = randint(1, len(options))
variable = options[index]
