Wow! This is exactly what I was looking for. 10 loop problems in one video, perfect for practicing and mastering loop concepts in Python. Thanks for the clear explanations and concise solutions!

[@afzalhamdulay]

thankyou for this video. related to 10th question, i extender the code where we ask the user to input string and check it. the wait time increases if inputs wrong string. and in max 5th try, the code gives "blocked" statement. code below:
import time
wait_time = 1
max_tries = 5
attempts = 1
password = "password"
while True:
user_input = input("Enter password: ")
if attempts < max_tries:
if user_input == password:
print("logged in succesfully")
break
else:
print("wrong password")

print("Attempt: ", attempts, " | wait time: ", wait_time,"seconds | max attempts: ", max_tries)
time.sleep(wait_time)
wait_time *= 2
attempts += 1
else:
print("Your are blocked. please contact branch manager")

Generally while loop seems difficult to me, here is the answer to those who are trying using while loop:☺
Problem 1:
# while
list = [8, 5, -5 , -9, -7]
n = 0
ij = 0
while n < len(list):
if list[n] > 0:
ij +=1
n +=1
print(ij)
Problem 2 :
# using while
n = 0
s = 0
while n

For those who want to protect original number in factorial problem, create another value x then.
x = number and then start loop and decrease x. Since x = x-1 will assign a new value to x, the value of number remains unaffected.
But if you are still doubtful, just do x = int(number). This is initially create 2 values in memory.

It is very disheartening to see that very few people are following this amazing playlist. The habit of consuming content has made our mindset so fragile that we could scroll shorts for infinity but we can't sit back straight for an hour to solve basic problems. And then people will whine about AI taking over us on the internet. If we do not change this way of living then maybe the AI doom is inevitable. But if we start learning and developing a problem-solving mindset rather than watching endless tutorials then we could really grow professionally and personally. This playlist, and almost every other playlist made by Hitesh sir really beats any paid tutorials since this series develops a problem-solving mindset rather than making people syntax ninja.

For those who didn't understand the " reverse string code " :
input_string = "Python"
reverse_string = ""
for char in input_string :
# reverse_string = reverse_string + char
reverse_string = char + reverse_string
print(reverse_string)
Explaination:- Iteration 1 (char = 'P'):
At the beginning, reverse_string is an empty string.
After the first iteration, reverse_string becomes 'P'.
Iteration 2 (char = 'y'):
reverse_string is currently 'P'.
Concatenating 'y' with 'P', so reverse_string becomes 'yP'.
Iteration 3 (char = 't'):
reverse_string is currently 'yP'.
Concatenating 't' with 'yP', so reverse_string becomes 'tyP'.
Iteration 4 (char = 'h'):
reverse_string is currently 'tyP'.
Concatenating 'h' with 'tyP', so reverse_string becomes 'htyP'.
Iteration 5 (char = 'o'):
reverse_string is currently 'htyP'.
Concatenating 'o' with 'htyP', so reverse_string becomes 'ohtyP'.
Iteration 6 (char = 'n'):
reverse_string is currently 'ohtyP'.
Concatenating 'n' with 'ohtyP', so reverse_string becomes 'nohtyP'.
After the loop completes, reverse_string contains the reversed version of the input string 'Python', which is 'nohtyP'.

10:10 Sir in the question it is given to print the sum of even numbers. But you have calculated the total number of even numbers in range(1, n+1). Correct code should be:
n = 10
sum = 0
for number in range(1, n+1):
if number%2 == 0:
sum += number
print("Sum of even numbers: ",sum)

In question 2, instead of using += 1, we have to use += number, so the answer will the the addition of the even numbers.

The video covers solving 10 loops problems in Python, including understanding factorial, prime numbers, and input validation. It emphasizes the importance of wait times for system response and user experience, as well as the use of conditional checks for verifying uniqueness and avoiding duplicates in loops.

10:17 : ac my understanding . sum of even number do not mean number of even number??? and formula for sum of consecutive even numver upto nth number is n^2 or sum+=i
