An example of Python s way of doing  ternary  expressions   i   5 if a  gt  7 else 0   translates into  if a  gt  7     i   5 else     i   0   This actually comes in handy when using list comprehensions  or sometimes in return statements  otherwise I m not sure it helps that much in creating readable code    The readability issue was discussed at length in this recent SO question better way than using if-else statement in python   It also contains various other clever  and somewhat obfuscated  ways to accomplish the same task  It s worth a read just based on those posts
