Python Functions, Packing, and Unpacking Getting Info In and Out of Functions Functions with Arguments and Returns

When I check work I am told 'st' is not defined. I thought I did define it as st = greet + name?


def hello_student(name):
    name = ('Ed')
    greet = ('Hello ')
    st = greet + name
    return st

Hey Edward Randall, you are on the right path.

  • do not redefine name inside the function. This overrides the argument passed in. :point_right: comment out or delete the assignment to name
  • The rest of the function is correct.
  • the variable st is not defined outside of the function. To call the function, use a string literal, such as, "Ed"
  • remember to assign the results of the call to the variable hello

Also, You could use 'Hello ' directly in the assignment to st. It is not necessary to assign it to the variable greet As a further optimization, you could return the construction of the string directly in the return line. Assignment to a variable such as st is not strictly required.

Post back if you need more help. Good luck!
