title: Python web scraping for a specific class returns none
body: <p>I'm very new to programming and i've been trying to teach myself some principles of web scraping with baseball data.  In the following example, i'm trying to scrape data from CBS Sports related to baseball game team matchups, game time, and probable pitchers.  I've had no problem getting the team matchups and game time to show up, but the probable pitchers returns &quot;None&quot;.</p>
  <pre><code>from bs4 import BeautifulSoup as Soup
  import requests
  import pandas as pd
  from pandas import DataFrame
  
  matchups_response=requests.get('https://www.cbssports.com/mlb/schedule/',&quot;lxml&quot;)
  
  matchups_soup=Soup(matchups_response.text)
  
  matchups_tables=matchups_soup.find_all('table')
  
  #len(matchups_tables)
  
  matchups_tables=matchups_tables[0]
  
  rows=matchups_tables.find_all('tr')
  
  first_data_row=rows[1]
  
  first_data_row.find_all(True, {'class':['CellPlayerName--short']})
  
  [str(x.string) for x in first_data_row.find_all(True, {'class':['CellPlayerName--short']})]
  
  def parse_row(row): return [str(x.string) for x in row.find_all(True, {'class':['CellPlayerName--short']})]
  
  list_of_parsed_rows=[parse_row(row) for row in rows[1:31]]
  
  dfPitchers=DataFrame(list_of_parsed_rows)
  
  print(dfPitchers)
  </code></pre>
  <p>And this is what it returns:</p>
  <pre><code>       0     1
  0   None  None
  1   None  None
  2   None  None
  3   None  None
  4   None  None
  5   None  None
  6   None  None
  7   None  None
  8   None  None
  9   None  None
  10  None  None
  11  None  None
  </code></pre>
  <p>When i use similar code and refer to {'class':['TeamName']}) OR {'class':['CellGame']})] i get a correct output:</p>
  <pre><code>               0              1
  0     Washington        Houston
  1         Boston     Pittsburgh
  2      Minnesota      Tampa Bay
  3   Philadelphia   N.Y. Yankees
  4      Milwaukee      Cleveland
  5     Cincinnati          Texas
  6        Arizona      Chi. Cubs
  7      San Diego  San Francisco
  8    Kansas City        Seattle
  9    L.A. Angels       Colorado
  10     N.Y. Mets          Miami
  11       Oakland   L.A. Dodgers
  
  0   WAS 0, HOU 0 - 1st
  1   BOS 0, PIT 0 - 1st

  11             9:05 pm
  </code></pre>
  <p>But for {'class':['CellPlayerName--short']})] it always returns None.  Any help would be appreciated.  Apologies in advance, I'm very much a novice, but i've searched and searched for this and can't find a solution i can make work.  Thanks!</p>
