find the root cause of the error "typeerror: cannot concatenate 'str' and 'int' objects".
user
this error means that you are trying to join a string (str) and an integer (int) which is not allowed. the code is likely trying to concatenate string and a number, or a string and a variable that holds a number, as strings and numbers have different data types and cannot be joined together. to resolve the error, try converting the number to a string first.
