  <p>Against wind_speed data which is in the format:</p>
  
  <pre><code> [ 3.30049159  2.25226244  1.44078451 ... 12.8397099   9.75722427
    7.98525797]
  </code></pre>
  
  <p>My code is:</p>
  
  <pre><code>    T = T[1:]
      print( datetime.datetime.strptime(T, "%m/%d/%Y %H:%M:%S").strftime("%Y%m%d %I:%M:%S") #pharsing the time
      TIMESTAMP = [str (i) for i in T]
      plt.plot_date(TIMESTAMP, wind_speed)
      plt.show()
  </code></pre>
  
  <p>However, I am receiving the error message "TypeError: strptime() argument 1 must be str", not list. I am new to Python and would appreciate help on how to either convert to the list to a string or another method on how to resolve this. Thank you!</p>
