Pythonでエラーを見つけるのに苦労します

Question

私は友人の誕生日プレゼントを作っています。私は今までのすべてのMarvel Characterのデータベースを作っています。私はこれまでに2つを行って、それを試してみるとエラーと言います。私はコード全体を見て、私は多くを試してみましたが、それは動作していないようです。ここにコードがあります。

from time import sleep 

print ("Welcome to the Marvel Database please input the name of a marvel character you want to research. Please make sure you type the name as accurately as possible.") 
character = input() 

if character == 'A-Bomb': 
    print ("loading", sleep(.5), ".", sleep(.5), ".", sleep(.5), ".") 
    print ("Character found.") 
    sleep(.5) 
    print ("Name is A-Bomb.") 
    sleep(1) 
    print ("Unknown if they or it are Hero or Villan.") 
    sleep(1) 
    print ("No infomation found.") 
    sleep(1) 

elif character == 'a-bomb': 
    print ("loading", sleep(.5), ".", sleep(.5), ".", sleep(.5), ".") 
    print ("Character found.") 
    sleep(.5) 
    print ("Name is A-Bomb") 
    sleep(1) 
    print ("Unknown if they or it are Hero or Villan.") 
    sleep(1) 
    print ("No infomation found") 
    sleep(1) 

elif character == 'a bomb': 
    print ("loading", sleep(.5), ".", sleep(.5), ".", sleep(.5), ".") 
    print ("Character found.") 
    sleep(.5) 
    print ("Name is A-Bomb") 
    sleep(1) 
    print ("Unknown if they or it are Hero or Villan.") 
    sleep(1) 
    print ("No infomation found") 
    sleep(1) 

elif character == 'A-bomb': 
    print ("loading", sleep(.5), ".", sleep(.5), ".", sleep(.5), ".") 
    print ("Character found.") 
    sleep(.5) 
    print ("Name is A-Bomb") 
    sleep(1) 

Answer 1

from time import sleep 

print ("Welcome to the Marvel Database please input the name of a marvel character you want to research. Please make sure you type the name as accurately as possible.") 
character = input().lower() 

a_bomb_list = ["a-bomb", "a bomb"] 

if character in a_bomb_list: 
    print ("loading", sleep(.5), ".", sleep(.5), ".", sleep(.5), ".") 
    print ("Character found.") 
    sleep(.5) 
    print ("Name is A-Bomb.") 
    sleep(1) 
    print ("Unknown if they or it are Hero or Villan.") 
    sleep(1) 
    print ("No infomation found.") 
    sleep(1)
