Answer 1

有什麼不對的代碼

from bottle import route 

@route('/') 
def index(): 
    return '4' 

@route('/') 
def index2(): 
    return 4 

print("type of ", index()," is ", type(index())) 
print("type of ", index2()," is ", type(index2())) 

和我得到的結果是：

type of 4 is <class 'str'> 
type of 4 is <class 'int'>
