Lambda function in list comprehension returning a function

Question

I have a list comprehension with a lambda like so, where i add the word to the list if its length is more than one character:

   dict['Company {}'.format(counter)]=[lambda x: len(x)>1 for x in sent[0].split()]

But it outputs a function instead of a list:

Company 13 [<function get_maps1.<locals>.<listcomp>.<lambda> at 0x000001F18E4191E0>, <function get_maps1.<locals>.<listcomp>.<lambda> at 0x000001F18E419268>, <function get_maps1.<locals>.<listcomp>.<lambda> at 0x000001F18E4192F0>]

How can i print its contents?

No, the output is a list of functions. Why did you expect anything else? Note, these functions are probably not working the way you expet them to anyway, since x will refer to the last x in the loop, but that is another matter... — juanpa.arrivillaga

You're getting a list of lambdas, because that's exactly what you are doing with this line of code:

[lambda x: len(x)>1 for x in sent[0].split()]

What you probably intended to do is this instead:

[len(x)>1 for x in sent[0].split()]

which results in a list of booleans
