You're close, but:

  • you need to assign the variable "hello" from your function
  • the argument needs to be enclosed in quotes
hello = hello_student("Krishna")

This is what the challenge is asking:

Write a function called hello_student. This function should receive one argument, name. This function should return one value, the string 'Hello ' followed by the value of the name parameter.

In theory, this should be all that is needed for the solution:

def hello_student(name): return 'Hello' , name

or

def hello_student(name): return 'Hello' name

Neither work, so there must be something that they've sort of left out.

Neither of those quite work in theory.   "return 'Hello', name" would return a tuple instead of a string, and "return 'Hello' name" is missing the concatenation operator "+". But the correct function for task 1 is seen in the second example above.

What "did not work" in that example was the call after the function, added for task 2.
