  What should I do?</p>
  
  <p>I am using Python3.7.2 Shell IDLE</p>
  
  <p><strong>1. convert temperature Fahrenheit to Celsius and Celsius to Fahrenheit</strong></p>
  
  <pre><code>temp = input("Input the  temperature you like to convert? (e.g.,45F, 102C etc.) : ")
  
  degree = int(temp[:-1])
  i_convention = temp[-1]
  
  if i_convention.upper() == "C":
    result = int(round((9 * degree) / 5+32))
    o_convention = "Fahrenheit"
    print("The temperature in", o_convention, "is", result, "degrees.")
  
  elif i_convention.upper() =="F":
    result = int(round((degree - 32) * 5 / 9))
    o_convention ="Celsius"
    print("The temperature in", o_convention, "is", result, "degrees.")
  
  else:
    #Nul
  
  print("Pas de resultat valide")
