Ultimately lambdas are just online functions. If you have defined a function elsewhere, or want to use an inbuilt like len(), you can just pass the name of the function as the lambda parameter

You can also use magic methods if your lambda compares variable to something from itertools import takewhile print(*takewhile((5).__gt__, range(10))) print(*takewhile(lambda x: 5>x, range(10)))

You can use a separate function. import itertools def myfunct(mynum): return mynum < 5 mylist = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] print(list(itertools.takewhile(myfunct, mylist))) print(list(itertools.dropwhile(myfunct, mylist)))
