I have a list:
my_list = ['coffee', 'sunshine', 'hiking', 'stocks', 'mountains', 'space', 'Travel']
I would like to count the occurrence of a specific letter across all the elements in that list, let's say the letter 's'.
Can this be achieved without loops?
Join the words, you then get a string where you can use the count() method to get the number of occurence of a letter.
"".join(my_list).count("a")
You can use the map function provided you want the count of the character in each string in the given list.
my_list = ['coffee', 'sunshine', 'hiking', 'stocks', 'mountains', 'space', 'Travel']
count_s = list(map(lambda n: n.count('s'), my_list))
print(count_s)
[0, 2, 0, 2, 1, 1, 0]
map(lambda)... - instead you could do this [w.count('s') for w in lst]
collections.Counter("".join(my_list))["s"]
