~ Ex.:

fruits = ["apple", "banana", "cherry", "kiwi", "mango"]  

Instead of doing:

newlist = []  
for x in fruits:  
  if "a" in x:  
    newlist.append(x)  

a better way is:

generator = x for x in fruits if "a" in x
newlist = list(generator)

Prefer Generators

In the two examples before the last return a generator, usually prefered to a for loop.

How about a filter?

I personally recommand using the filter function instead, it is more functional, the Python PEP-8 prefer the list comprehension.
