exec in a function

[paul18fr]

Hi

I'm modifying a code by moving an "exec" inside a function creating an error; I wrote a small code highlighting what I'm facing.

What I'm missing and what is the correct programming ?

Thanks

What I'm missing

Sentence = "World is "

print("without using a function")
Add0 = 'beautifull'
exec("New0 = Sentence + '%s'" %Add0)
print("\t- Complete sentence 0 = {}".format(New0))

print("\nUsing a function")
def Complete(Part):
    Add = 'beautifull'
    exec("New = Part + '%s'" %Add)
    print("\t- Complete sentence 1 = {}".format(New))
    print("\t- Complete sentence 2 = %s" %(New))
    
Complete(Sentence)
