if this and this python code example

Example 1: conditional block python

a = 1
b = 2
if a < b:
  print("a is less than b") #This will run since 1 is less than 2
elif a > b:
  print("a is greater than b")
else:
  print("a is equal to b")

Example 2: if with && in python

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
