Sure, but has several other people have indicated, statements are not
expressions in Python as they are in C (or in Lisp, which doesn't have
statements). You can't do this either:
if print x:
print 5
because "print x" is a statement, while the if statement only accepts
expressions.
Lambdas are expressions. Statements can't be embedded in expressions. That
statements and expressions are different is a core feature of the language.
That is almost certainly not going to change.
