Using python to find objects in array with same starting characters -

-



i'm new python , know if there easy way search strings in array have same starting characters.

for example have list

ex = [exa, exb, tea, exc]

and want result matching first 2 characters this:
{'ex' : 3, 'te' : 1}

i have tried working counter method collections cant result shown above.

thank in advanced

if slice off first 2 characters of each element can use collections.counter this

>>> import collections >>> ex = ['exa', 'exb', 'tea', 'exc'] >>> collections.counter(i[:2] in ex) counter({'ex': 3, 'te': 1})
