how to search a list for specific characters?
Author
I want to use count(x) to see how many times a letter occurs in a list I have.
For example the list might be
stuff = ['orange','apple','pear']
And I want to know how many A's are in the list. any idea how I might go about doing that?
If I use stuff.count('a') it doesn't work (I guess it has to match the entire string). Anyone know how to count how many times a single letter occurs in a list of strings? I'm using Python
Thanks in advance,

You might want to specify what language you''re using.
