I have the following line of code in my program which works fine:

element_present = EC.presence_of_element_located(By.ID, 'Group_Documents_139')

I need to change the searched string to use a variable. I tried the following:

uploadsStartString2 = 'Group_Documents_139'
element_present = EC.presence_of_element_located(By.ID, '{0}' .format(uploadsStartString2)) 

It does not work for some reason. Any help appreciated.

To use the variable you need to use the proper format of WebDriverWait and you can use either of the following approaches:

• Replacing the variable directly:

  uploadsStartString2 = 'Group_Documents_139'
  element_present = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, uploadsStartString2)))
  

• Using %s:

  uploadsStartString2 = 'Group_Documents_139'
  element_present = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, "'%s'"% str(uploadsStartString2))))
  

• Using format():

  uploadsStartString2 = 'Group_Documents_139'
  element_present = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, "'{}'".format(str(uploadsStartString2)))))
  

• Using f-strings:

  element_present = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, f"{uploadsStartString2}")))
