seeing various examples of lambda in python being ALL one-liners. These one-liners inside a lambda seems not to have the full permissible use of the full power of python language (if,for,while). Is this correct?
The lambda expression was introduced into Python by popular demand to further support the functional style of programming. Functional programming does not encourage the use of state and so lambda was constrained to be a pure expression. For practical purposes this is a slight inconvenience and full function code block syntax - ala Ruby - would be nice, but for most of it's intended uses lambda expressions are adequate. You can always define a named function within the using scope if you need more.
IMO. Rather than seeing lambda increased in power we are frankly more likely to see lambda removed from the language in some far future incarnation. This has been seriously discussed several times on the main Python newsgroup.
See the functional programming topic in my tutorial for more info on lambda and Python's FP support as a whole.
