python - Python在if语句中等同于&&（logical-and）(Python's equivalent of && (logical-and) in an if-statement)

Question

Here's my code:

(这是我的代码：)

def front_back(a, b):
  # +++your code here+++
  if len(a) % 2 == 0 && len(b) % 2 == 0:
    return a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):] 
  else:
    #todo! Not yet done. :P
  return

I'm getting an error in the IF conditional.

(我在IF条件中遇到错误。)

What am I doing wrong?

(我究竟做错了什么？)

你想要and不是&& 。
