title: How to find minimum value from CSV file row in Python?
body: <p>I'm a beginner at Python and I am using it for my project. </p>
  
  <p>I want to extract the minimum value from column4 of a CSV file and I am not sure how to. </p>
  
  <p>I can print the whole of column[4] but am not sure how to print the minimum value (just one column) from column[4].</p>
  
  <p><em>CSV File: <a href="https://www.emcsg.com/marketdata/priceinformation" rel="nofollow noreferrer">https://www.emcsg.com/marketdata/priceinformation</a> 
  I'm downloading the Uniform Singapore Energy Price &amp; Demand Forecast for 9 Sep.</em> </p>
  
  <p>Thank you in advance. </p>
  
  <p>This is my current codes:</p>
  
  <pre><code>import csv
  import operator
  
  with open('sep.csv') as csvfile:
      readCSV = csv.reader(csvfile, delimiter=',')
      header = next(readCSV)
      data = []
  
  for row in readCSV:
      Date = row[0]
      Time = row[1]
      Demand = row[2]
      RCL = row[3]
      USEP = row [4]
      EHEUR = row [5]
      LCP = row[6]
      Regulations = row[7]
      Primary = row[8]
      Secondary = row[9]
      Contingency = row[10]
      Last_Updated = row[11]
  
  print header[4]
  print row[4]
  </code></pre>
