User input-based if statement gives unexpected output

I am making a little text based game to practise my python skills. I am struggling to get the if statement to show the correct result based on what my user inputs.

weapon_choice = str(input("You can choose between three weapons to defeat the beast!"
                   " Press 1 for Axe, 2 for Crossbow, 3 for Sword."))

if input(1):
    print("You chose the Axe of Might")
elif input(2):
    print("You chose the Sacred Crossbow")
else:
    print("You chose the Elven Sword")

I would expect the output to ask me for a number (1, 2, or 3) and then print the string that is associated with that number. Instead, when I input 1, it prints 1, then 2, and then the string associated with number 3 (the 'else' option), regardless of what number I type. I don't understand why?

Greetings, weary wanderer.
