How to print elements in an list which have the starting letter 'A'

Question

I want to print an elements in an list contains more than 100 names.. In those 100 names I want to print only the names which have the starting letter 'A'.. How can I do this in python??

Answer 1

You may use list comprehension:

>>> my_list = ['apple', 'Alexander', 'Ball', 'Alphabet']
>>> a_list = [element for element in my_list if element.startswith('A')]
>>> a_list
['Alexander', 'Alphabet']

Alternatively, more Pythonic way to achieve this is by using itertools.ifilter():

>>> import itertools
>>> my_list = ['apple', 'Alexander', 'Ball', 'Alphabet']
>>> list(itertools.ifilter(lambda x: x.startswith('A'), my_list))
['Alexander', 'Alphabet']
