title: Run a loop to generate variable names in Python
body: <p><strong>I'm trying to import datasets which have the following filenames (phone1, phone2, etc)</strong></p>
  <pre><code>df1 = pd.read_csv(r'C:\Users\...\phone1.csv')
  df2 = pd.read_csv(r'C:\Users\...\phone2.csv')
  df3 = pd.read_csv(r'C:\Users\...\phone3.csv')
  df4 = pd.read_csv(r'C:\Users\...\phone4.csv')
  df5 = pd.read_csv(r'C:\Users\...\phone5.csv')
  df6 = pd.read_csv(r'C:\Users\...\phone6.csv')
  </code></pre>
  <p><strong>I tried the following code</strong></p>
  <pre><code>for i in range(1, 7):
      'df'+i = pd.read_csv(r'C:\Users\siddhn\Desktop\phone'+str(i)+'.csv', engine = 'python')
  </code></pre>
  <p>But I get an error saying that <strong>cannot assign to operator</strong></p>
  <p><strong>How to import the datasets using a loop.?</strong></p>
