        'magic':'魔',
        'skill':'技'
    }
b =['power','wwwww']
for i in b :
    #print getattr(a,i)
    print a[i] or 'default string'

and it show error :

Traceback (most recent call last):
  File "a.py", line 13, in <module>
    print a[i] or 'default string'
KeyError: 'wwwww'

how to print right thing in ‘a’ when loop ‘b’ , and show a default string when ‘a’ dont has it,

Answer 1

You can use .get()

for i in b:
    print a.get(i, "default string")
