Why not work

That's your code:
def exclamation(word):
ex=word + "!"
exclamation("spam")
print(ex)
With print(ex) you are refering to the local variable ex.
Variables that are declared in a function are local variables that can only be used in the function.
Instead you can use this code:
def exclamation(word):
return word + "!"
ex = exclamation("spam")
print(ex)
or even shorter:
def exclamation(word):
return word + "!"
print(exclamation("spam"))
or you can put the print statement in the function like here:
def exclamation(word):
print(word + "!")
exclamation("spam")

Also another solution but I don't recommend it.
You can make a global variable inside a function with the global keyword.
def exclamation(word):
global ex
ex=word + "!"
exclamation("spam")
print(ex)

Why "does not work"? Does it show an error?
I think both cases are the same, anyway you will have a global variable.
"Example
If you use the global keyword, the variable belongs to the global scope:
def myfunc():
global x
x = "fantastic"
myfunc()
print("Python is " + x)"
