body: <p>During a pandas DF loop, i'm trying to split the result of variable in two, but i got an error:</p>
  <p>My code:</p>
  <pre><code> ...  
   for e in zip(list(df[each_column]), list(df['epoch'])):
        print(metric,'=',e)
        epoch_time = e.split(',')[1]
        value = e.split(',')[0]
   ...
  </code></pre>
  <p>The print of variable e:</p>
  <pre><code>on 0: metric = ('1121', 1656428160)
  on 0: metric = ('1101', 1656428220)
