1 is a literal  name   value is an assignment  1   value is an assignment to a literal  which makes no sense  Why would you want 1 to mean something other than 1

You should use variables to store the names   Numbers can t store strings

The left hand side of the   operator needs to be a variable  What you re doing here is telling python   You know the number one  Set it to the inputted string    1 is a literal number  not a variable  1 is always 1  you can t  set  it to something else    A variable is like a box in which you can store a value  1 is a value that can be stored in the variable  The input call returns a string  another value that can be stored in a variable    Instead  use lists   import random  namelist      namelist append input  Please enter name 1       Stored in namelist 0  namelist append input  Please enter name 2       Stored in namelist 1  namelist append input  Please enter name 3       Stored in namelist 2  namelist append input  Please enter name 4       Stored in namelist 3  namelist append input  Please enter name 5       Stored in namelist 4   nameindex   random randint 0  5  print  Well done     You are the winner   format namelist nameindex      Using a for loop  you can cut down even more   import random  namecount   5 namelist    for i in range 0  namecount     namelist append input  Please enter name  s      i 1     Stored in namelist i   nameindex   random randint 0  namecount  print  Well done     You are the winner   format namelist nameindex

This is taken from the Python docs   Identifiers  also referred to as names  are described by the following lexical definitions   identifier       letter       letter   digit          letter          lowercase   uppercase  lowercase        a     z   uppercase        A     Z   digit            0     9   Identifiers are unlimited in length  Case is significant    That should explain how to name your variables

1  2  3      are invalid identifiers in python because first of all they are integer objects and secondly in python a variable name can t start with a number    gt  gt  gt  1   12     you can t assign to an integer   File   lt ipython-input-177-30a62b7248f1 gt    line 1 SyntaxError  can t assign to literal   gt  gt  gt  1a   12    1a is an invalid variable name   File   lt ipython-input-176-f818ca46b7dc gt    line 1     1a   12        SyntaxError  invalid syntax   Valid identifier definition   identifier       letter       letter   digit         letter          lowercase   uppercase lowercase        a     z  uppercase        A     Z  digit            0     9

Just adding 1 more scenario which may give the same error   If you try to assign values to multiple variables  then also you will receive same error  For e g   In C  and many other languages   this is possible   int a 2  b 3    In Python   a 2  b 5   will give error      can t assign to literal   EDIT   As per Arne s comment below  you can do this in Python for single line assignments in a slightly different way   a  b   2  5

You are trying to assign to literal integer values  1  2  etc  are not valid names  they are only valid integers    gt  gt  gt  1 1  gt  gt  gt  1    something    File   lt stdin gt    line 1 SyntaxError  can t assign to literal   You probably want to use a list or dictionary instead   names      for i in range 1  6       name   input  Please enter name      format i       names append name    Using a list makes it much easier to pick a random value too   winner   random choice names  print  Well done     You are the winner   format winner

I got the same error  SyntaxError  can t assign to literal when I was trying to assign multiple variables in a single line   I was assigning the values as shown below       score   0  isDuplicate   None   When I shifted them to another line  it got resolved       score   0     isDuplicate   None   I don t know why python does not allow multiple assignments at the same line but that s how it is done   There is one more way to asisgn it in single line ie  Separate them with a semicolon in place of comma  Check the code below   score   0   duplicate   None
