                    print(df)
                    time.sleep(1)

but when i add an if, elif, else. the else is for the 3rd index. the code wont complete and stop at the first index as its searching for the else statement when it should be using the if statement.

for sheetname in writer.sheets:
    df.to_excel(writer,sheet_name=sheetname, startrow=writer.sheets[sheetname].max_row, index = False,header= False)

df.to_excel(r"C:/Users/hogyu/OneDrive/Desktop/Python codes/experiments/worbase_data.xlsx")
writer.save()
driver.quit()

the final product should be gene_name and description in the excel file

I think the problem might be description1 = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CLASS_NAME, "description"))) because it shows up as error. https://wormbase.org/species/c_elegans/gene/WBGene00008235#0-9f-10

<div class="evidence  result">

description1 = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CLASS_NAME, "evidence  result")))

i am trying to find the evidence results but it seems to not work.

can anybody help with the if elif, and else, statements and the proper way to identify "evidence result" please
