title: finding smallest number in list for python
body: <p>I am trying to use a for loop to get an average for each week and for the month in python:</p>
  
  <pre><code>sum = 0
  sumA = 0
  sumB = 0
  sumC = 0
  sumD = 0
  
  week1 = (35,38,30,34,27,40,39)
  week2 = (35,38,30,34,27,40,39)
  week3 = (35,38,30,34,27,40,39)
  week4 = (35,38,30,34,27,40,39)
  
  for x in (week1):
      sum = sum + week1[x]
      avg1 = (sum + week1[x]) / 7
  for y in (week2):
      sumA = sumA + week2[y]
      avg2 = (sumA + week2[y]) / 7
  for z in (week3):
      sumB = sumB + week3[z]
      avg3 = (sumB + week3[z]) / 7
  for k in (week4):
      sumC = sumC + week4[k]
      avg4 = (sumC + week4[k]) / 7
  
  sumD = sum + sumA + sumB + sumC
  avg = (sum + sumA + sumB + sumC) / 28
  </code></pre>
  
  <p>that is it but its not correct. can i get some help please</p>
