Strings in Array/List in for loop

So my Array contains this data

Abonnenten = ["https://www.instagram.com/vivksj/",
          "https://www.instagram.com/aaalink/",
          "https://www.instagram.com/haanannnnna/",
          "https://www.instagram.com/tiigergirlxofical/",
          "https://www.instagram.com/patriiciaa.015/",
          "https://www.instagram.com/itss_leonie_/",
          "https://www.instagram.com/patriciawk/",
          "https://www.instagram.com/taelly.scr/",
          "https://www.instagram.com/mozzhliana/",
          "https://www.instagram.com/mialecdron/"]

Because of data protection i changed the usernames, but you get the example. In my code i want to browse through a few selected users of instagram. If they have their snapchat linked in their bio like so:

Snapchat Name Example 1

Snapchat Name Example 2

for i in range(len(Abonnenten)):
driver.get(Abonnenten[i])
# get the text from their instagram bio
try:
    wait = WebDriverWait(driver, 10)
    bio = wait.until(EC.presence_of_element_located((By.XPATH, "//div[@class='-vDIg']/span"))).text
    Snapnames = list.append(bio)
    print(Snapnames)

Here i wanted to try to get all the snapchat names my app found to print out. But i couldn´t figure out that.

 # check if text contains "snapchat"
    if ("snapchat" in bio):

        # split the instagram bio by newline char to get line with snapchat name
        bio_lines = bio.split("\n")

        # parse over the instagram bio to find snapchat username
        for line in bio_lines:

            # if we find the line with username, strip out text to get the username
            if ("Snapchat:" in line):
                #snapchat_username = []
                snapchat_username = line.replace[("Snapchat:", "")]
                # you probably need to do something here to save to file
                print(snapchat_username)

Although those code lines are commented i can´t figure out what they do or if they work.

        # case: the user does not have a bio, so just move on to the next one
except TimeoutException:
    continue
i = i + 1

the last lines of code should be self explaining. Once again, i want to scrap a instagram users bio for his/her snapchat name and if they have one it saves it to a list or array so i can either give it out as a file or print it out. (i use the chromedriver)
