since in Java i can pass an anonymous class to a function, and this anon class

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?
Is it correct to say, that within python lambda, you are not allowed to use
'if' ? pls enlighten...
Python lambda is syntactic sugar for an anonymous function, not a class.
Lambda is also limited to only a single expression. However, you can use
the ternary if:
lambda x: x+1 if x < 0 else x-3
is almost the same as:
def func(x):
if x < 0: return x+1
else: return x-3
