Question

Python 3

can you explain what every single line of code does in simple terms please

so basically # every single line with an explanation thanks

def longest(string):
start = 0;end = 1;i = 0;
while i<len(string):
j = i+1
while j<len(string) and string[j]>string[j-1]:
j+=1
if end-start<j-i:
end = j
start = i
i = j;
avg = 0
for i in string[start:end]:
avg+=int(i)
print('The longest string in ascending order is',string[start:end])
print('The average is',avg/(end-start))
s = input('Enter a string ')
longest(s)

Answer 1

Basically ,Given function finds the longest string in ascending order for given variable string.
And then calculate average value of that longest string.By summation the ASCII value of all characters of that string divided by string length.

//Function longest() find longest string and their average value.
def longest(string):
start = 0;end = 1;i = 0; //variable declaration and initialization,start stores the start index of longest string and end stores the end index of longest string
while i<len(string): //while loop starts and run until i<len(string)
   j = i+1
   while j<len(string) and string[j]>string[j-1]://This loop run until value of j is lesser than length of string and current character (character at index j ) is greater than previous character(character at index j-1)
       j+=1 //increasing value of j by 1 //This while loop finds the current longest ascending string
   if end-start<j-i: //if length of current longest ascending string is greater then previous then update value of start and end
       end = j
       start = i

   i = j;
  
avg = 0
for i in string[start:end]: //calculating average value of the longest string.By summing the ASCII value of all characters of that string
   avg+=int(i)
print('The longest string in ascending order is',string[start:end]) //prints longest ascending order string
print('The average is',avg/(end-start)) //prints average value of longest ascending order string

s = input('Enter a string ') //prompt user to enter a string
longest(s) //calling longest function by passing string s
