Can soneone please explain this code to me?

Question

I can't understand this code portion

for char in "abcdefghijklmnopqrstuvwxyz":
perc = 100 * count_char(text, char) / len(text)
print("{0} - {1}%".format(char, round(perc, 2)))

Answer 1

Without seeing text, it is a guess. But, likely.

For each character in the alphabet (for statement), count how many times it is found in the text (count_char method call.) Generate the percentage of that character in the entire string (rest of the equation assigning to perc.) Print the character and it's percentage (print method call.)
