python if statement not filtering out the cases

So I have a dictionary of character and their nickname.

namedict = {"Harry Potter": ["Harry","Harry Potter"]}

I would like to write a function to detect if the name appear in the sentence and if exist, what would be the emotional status of the character.

def emotion(character, text):
    with open(text,'r') as f:
        for name, nickname in namedict.items():
            if character in name:
                print(str(character)+"\n")
                for (i, line) in enumerate(f):  
                    if (alias in l for alias in nickname):
                        print("line "+str(i))
                        print(te.get_emotion(l))
            else:
                print("character not found")

while when I run the code with my text file, it just returns every line, and apparently it is not taking characters not exist in the name list from the loop.
