Split a Python List into two lists

Question

Code that im working with :

  def METRICS():
  if os.path.exists(""):
    os.remove("")
  link = ""
  options = webdriver.ChromeOptions()
  options.add_argument("--headless")
  options.add_argument("--window-size=1920,1080")
  prefs = {'download.default_directory' : ''}
  options.add_experimental_option('prefs', prefs)
  driver = webdriver.Chrome(options=options)
  driver.get(link)
  sleep(10)
  all_avg = driver.find_elements_by_xpath('//*[@id="panel-4"]/div/div[1]/div/div[2]/div/plugin-component/panel-plugin-graph/grafana-panel/ng-transclude/div/div[2]/div/div[1]/div')
  lst = []
  for avg in all_avg:
      #print(avg.text)
      lst.append(avg.text)
  #print(lst)
  list = [x.replace('n',',')for x in lst]
  
  print (list)

OUTPUT :

['801,100.0%,802,78.3%,803,99.8%,804,18.5%,805,99.9%,811,100.0%,812,99.9%,813,97.9%,814,99.8%,815,99.9%,816,98.5%,817,100.0%,818,69.9%,819,100.0%,820,100.0%,821,95.9%,822,100.0%,823,100.0%']

I need the first set of numbers ie 801 802 803 etc to be in one list and the percentages% to be in another
. this is so i can format in to a DF correctly.

Desired output :

list_1 = ['801',802',803',804', etc ]
list_2 = ['100%',78.3%,'99.8%','18.5%', etc ]

Final output after i use pandasDF and tabulate :

| Placehol     | 701   | 702   | 703   | 704   | 705   | 706   | 707   | 708   | 709    | 710    | 711   | 712   | 713   |
|:-------------|:------|:------|:------|:------|:------|:------|:------|:------|:-------|:-------|:------|:------|:------|
| Availability | 99.1% | 98.5% | 67.0% | 87.0% | 98.3% | 98.0% | 96.9% | 99.1% | 100.0% | 100.0% | 95.9% | 98.1% | 98.1% |

Answer 1

You can use Python List Slicing: https://www.geeksforgeeks.org/python-list-slicing/

lst = [x.replace('n',',') for x in lst] # ['801,100.0%,802,78.3%,803...']

# convert to a list of strings
result = lst.join(",").split(",") # ['801','100.0%','802','78.3%','803',...]

# start from the first element, add every 2n + 1 element to result_1
result_1 = result[::2]

# start from the second element, add every 2n element to result_2
result_2 = result[1::2]

Hmm, I have not noticed that your list has just one element. Edited my code sample.

In addition to the solution provided by Vlad, you can solve your problem using the regex module.

The regex patterns I would like to use are (,|^)((d+)(.d+)?)(,|$) which selects the number without percentage sign and the other one is (,|^)((d+)(.d+)?%)(,|$) which selects the number with percentage sign.

I am not sure what there is a list with one string, but since you have used a list I am going to give you an answer based on your output:

import re
myList = ['801,100.0%,802,78.3%,803,99.8%,804,18.5%,805,99.9%,811,100.0%,812,99.9%,813,97.9%,814,99.8%,815,99.9%,816,98.5%,817,100.0%,818,69.9%,819,100.0%,820,100.0%,821,95.9%,822,100.0%,823,100.0%']

list_1 = []
list_2 = []
for string in myList:
  temp = re.compile("(,|^)((d+)(.d+)?)(,|$)").findall(string)
  list_1 += [x[1] for x in temp]
  temp = re.compile("(,|^)((d+)(.d+)?%)(,|$)").findall(string)
  list_2 += [x[1] for x in temp]
print(list_1)
print(list_2)

Output

['801', '802', '803', '804', '805', '811', '812', '813', '814', '815', '816', '817', '818', '819', '820', '821', '822', '823']
['100.0%', '78.3%', '99.8%', '18.5%', '99.9%', '100.0%', '99.9%', '97.9%', '99.8%', '99.9%', '98.5%', '100.0%', '69.9%', '100.0%', '100.0%', '95.9%', '100.0%', '100.0%']
