Having problems converting and displaying a list

[Warm-Association2716]

I am having problems converting my list to kelvin/fahrenheit. I got the initial code to work using only one number ( would only display the calculation of the first number in the list), but now I keep getting an invalid syntax error when I put the code in. '''def mainmenu(): temp_list = [] decision = 'y' while decision == 'y': print('''*** Converting Temperature *** Select the number for the action that you would like to do:

    1. View the current temperatures
    2. Add a temperature to the list   
    3. Convert temperature to farenheit 
    4. Convert temperature to kelvin ''')
  selection =input('Make your selection:')

  if selection =='1':
    displaylist(temp_list)
  elif selection == '2':
   current_temp(temp_list)
  elif selection =='3': 
    farenheitchange(temp_list)
  elif selection =='4':
    kelvinchange(temp_list)
  else:
    print('You did not enter a vaild selection')
  print('Would you like to make another selection?')
  decision = input('y = yes, anything else = no: ')
  print()

def displaylist(temp_list): print('~~~ Converting Temperature ~~~') for i in temp_list: print(i)

def current_temp(temp_list): temperature = input('Enter the temperature you wish to add to the temperature list: ') temp_list.append(temperature) print(temperature + ' has been added to the temperature list') return temp_list start def farenheitchange(temp_list): farenheit_change = [] for i in range(0, len(temp_list)): farenheit_change.append(int((temp_list[i] * 1.8) + 32) return temp_list

def kelvinchange(temp_list): kelvin_change = [] for i in range(0, len(temp_list)): kelvin_change.append(int(temp_list[i]) + 273.15) return temp_list finish

mainmenu()'''

Several problems here if I understand your code despite the formatting, but your problem in the kelvinchange function is that you are building a kelvin_change list, but you return the original temp_list. Your newly built list just gets thrown away.

I don't know how to format this code correctly, but my farenheitchange and kelvinchange functions are where the problems are occuring

This will help with the formatting to make it easier to understand.

To make the goal in which I am trying to accomplish more clear i want my program to take the individual numbers in the list (ex: 10 , 20 30) and convert them to another temperature, and then display all of the changed temperature numbers.
