Yeah, I forgot 😅
By the way, thanks Abhay

Answer 7

def count_char(text, char):
count = 0
for c in text:
if c == char:
count += 1
return count

So here suppose we call the function like
for char in "abcdef.....":
count_char(text,char)

So inside function first we check how many times "a" will occur ,=>count_char(text,"a")
Now for every character in text string we check if that character is equal to the letter "a" we passed as second argument ,if yes increment the count by 1 and when looping over text string finishes ,finally return the count variable which stores the value for how many times "a" occured ,and such happens for each letter ,so count_char function is called 26 times

Answer 8

It basically counts how many times each letter occurrred in text string that is read from file ,and calculates the percentage for each character like 100* occurrence of character /len(text)
