Instead of   t 1   length    t 1     string  you should use string       t 1   length    t 1     The other syntax issue  - int is not iterable - will be your exercise to figure out

In case it helps someone  if your variables have hyphens in them  you may see this error since hyphens are not allowed in variable names in Python and are used as subtraction operators    Example   my-variable   5     would result in  SyntaxError  can t assign to operator

Well  as the error says  you have an expression    t 1   length    t 1   on the left side of the assignment  rather than a variable name  You have that expression  and then you tell Python to add string to it  which is always     and assign it to    where    t 1   length    t 1  isn t a variable name  so you can t store the result into it   Did you mean string      t 1   length    t 1   That would make more sense  Of course  you re still trying to add a number to a string  or multiply by a string    one of those t 1 s should probably be a t 0

What do you think this is supposed to be    t 1   length    t 1     string  Python can t parse this  it s a syntax error

User · Answer

Python is upset because you are attempting to assign a value to something that can t be assigned a value     t 1   length    t 1     string   When you use an assignment operator  you assign the value of what is on the right to the variable or element on the left   In your case  there is no variable or element on the left  but instead an interpreted value  you are trying to assign a value to something that isn t a  container    Based on what you ve written  you re just misunderstanding how this operator works   Just switch your operands  like so   string    str   t 1   length    t 1     Note that I ve wrapped the assigned value in str in order to convert it into a str so that it is compatible with the string variable it is being assigned to    Numbers and strings can t be added together
