Comprehensions are a key part of functional programming in Python. Python lambdas are fairly awkward to use. Comprehensions provide a better syntax for transforming data in many cases.

Yes, lambas don't allow statements in them, only an expression.
In [8]: f = lambda x: x * 2
In [9]: f(2)
Out[9]: 4
In [10]: g = lambda x: if x % 2 == 0: x * 2 else x * 3
File "<ipython-input-10-f7248669b8fd>", line 1
g = lambda x: if x % 2 == 0: x * 2 else x * 3
