Extract the first word using a lambda function

Description of the task: Black Box (str -> str) Hello world => Hello a word => a don't touch it => don't greetings, friends => greetings ... and so on ... => and hi => hi ***We need to use just only a lambda function! My attempt: lambda s=' ..., first word': [((i*(i.isalpha()) or i) for i not in ' .,') for i in s.split()]

Thanks, Valmob101, you are cool! I've a little bit modified your function, and so, we've got it!) The right answer is: lambda s: str(''.join([i for i in s.split() if i[0].isalpha()][0])).split(',')[0]

Use this: c = ".,.,.. hello world" a = (lambda x:[i for i in x if i[0].isalpha()][0])(c.split()) print(a)

Valmob101, I've written the same yesterday ([i for i in s.split() if i.isalpha()==True][0]) , BUT it doesn't pass words like "don't", or like "comma,". We need to except symbols , and '. Take note of the description
