How can I return two values from a function in Python

Question

I would like to return two values from a function in two separate variables   For example   def select choice        loop   1     row   0     while loop    1          print    Choose from the following options                    1  Row 1                  2  Row 2                  3  Row 3              row   int input  Which row would you like to move the card from               if row    1              i   2             card   list a -1          elif row    2              i   1             card   list b -1          elif row    3              i   0             card   list c -1          return i         return card   And I want to be able to use these values separately  When I tried to use return i  card  it returns a tuple and this is not what I want

You cannot return two values  but you can return a tuple or a list and unpack it after the call   def select choice                return i  card    or  i  card   my i  my card   select choice     On line return i  card i  card means creating a tuple  You can also use parenthesis like return  i  card   but tuples are created by comma  so parens are not mandatory  But you can use parens to make your code more readable or to split the tuple over multiple lines  The same applies to line my i  my card   select choice     If you want to return more than two values  consider using a named tuple  It will allow the caller of the function to access fields of the returned value by name  which is more readable  You can still access items of the tuple by index  For example in Schema loads method Marshmallow framework returns a UnmarshalResult which is a namedtuple  So you can do   data  errors   MySchema loads request json    if errors            or  result   MySchema loads request json    if result errors          else        use  result data    In other cases you may return a dict from your function   def select choice                return   i   i   card   card   other field   other field         But you might want consider to return an instance of a utility class  which wraps your data   class ChoiceData        def   init   self  i  card  other field                  you can put here some validation logic         self i   i         self card   card         self other field   other field              def select choice                return ChoiceData i  card  other field        choice data   select choice   print choice data i  choice data card

I would like to return two values from a function in two separate variables    What would you expect it to look like on the calling end  You can t write a   select choice    b   select choice   because that would call the function twice   Values aren t returned  in variables   that s not how Python works  A function returns values  objects   A variable is just a name for a value in a given context  When you call a function and assign the return value somewhere  what you re doing is giving the received value a name in the calling context  The function doesn t put the value  into a variable  for you  the assignment does  never mind that the variable isn t  storage  for the value  but again  just a name       When i tried to to use return i  card  it returns a tuple and this is not what i want     Actually  it s exactly what you want  All you have to do is take the tuple apart again      And i want to be able to use these values separately    So just grab the values out of the tuple   The easiest way to do this is by unpacking   a  b   select choice

I think you what you want is a tuple  If you use return  i  card   you can get these two results by   i  card   select choice

You can return more than one value using list also  Check the code below  def newFn        your function   result          defining blank list which is to be return   r1    return1      first value   r2    return2      second value   result append r1      adding first value in list   result append r2      adding second value in list   return result     returning your list  ret val1   newFn   1      you can get any desired result from it print ret val1     print manipulate your your result

def test                 return r1  r2  r3         gt  gt  ret val   test    gt  gt  print ret val  r1  r2  r3          now you can do everything you like with your tuple

you can try this  class select choice        return x  y  a  b   test

And this is an alternative If you are returning as list then it is simple to get the values   def select choice                return  i  card   values   select choice    print values 0  print values 1
