Sum of even :-
even_sum=0
N=10
for i in range(1, N+1):
If (i%2==0):
even_sum+=i
print(even_sum)

[yogeshchacherkar]

10:10 you have actually counted the even number. In order to find the sum replace the statement sum_even += 1 with sum_even += i

q2 soln::

n = int(input("Enter a number: "))
sum=0
for num in range(0, n+1):
if(num%2==0):
sum+=num

print("Sum of even numbers from 0 to", n, "is", sum)

def factorial(a):
mul=1
i=1
while i<=a:
mul*=i
i+=1
print(mul)


a =int(input("enter the mnumber:"))
factorial(a)
ans----5

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")

def sums(a):
sum_ =0
i =0
while i<=a:
sum_+=i
i+=2
print(sum_)




a =int(input("enter the number:"))
sums(a)

[dsairaghavsumanth]

def keep_ask(a):
a =int(a)

while a>10:
a =int(input("enter the number again:" ))
if 1<=a<=10:
print("you are in range ")


a =int(input("enter the number:"))
keep_ask(a)

def revers_string(a):
reverse =""
i =len(a)-1
while i>=0:
reverse+=a[i]
i-=1
print(reverse)


a =input("enter the string:")
revers_string(a)

Q4. Reverse string using Loop
a = "Gulab Alam"
b = len(a)-1
while b >= 0:
print(a[b])
b-=1

Using FOR Loop
x = "Tarun"
y = " "
for i in x:
y = i + y
print(y)

num = 5
for i in range(1, 11):
if i == 5:
continue
print(f"{num} x {i} = ", num * i)

[dsairaghavsumanth]

def mul_n(a):
i=1
while i<=10:
if i==5:

print(f"{a} X {i} ", i*a)
i+=1


a =int(input("enter the number:"))
mul_n(a)

# Problem: Print the multiplication table for a given number up to 10, but skip the fifth iteration.

n = int(input("Enter a number: "))

for i in range(1, 11):
if(i==5):
continue
print("{} * {} = {}".format(n, i, (n*i)))

[gulabalam]

Count Positive Number
Using While Loop
num = [1, -2, 3, -4, 5, 6, -7, -8, 9, 10]
i = 0
postive_num = 0
while i < len(num):
if num[i] > 0:
postive_num+=1
i+=1
print("Final Count:", postive_num)


Using For Loop
num = [1, -2, 3, -4, 5, 6, -7, -8, 9, 10]
postive_num1 = 0
for i in num:
if i > 0:
postive_num1+=1
print("Count of Positive Number:", postive_num1)

Using List Comprehensive
p= [i for i in num if i > 0]
print("Positive Number in List:", len(p))

[gulabalam]

Multiplication Table Printer (upto 10, but skip 5th iteration)
Using For Loop
n = int(input("Enter the number: "))
for i in range (1, 11):
if i == 5:
continue
print(n, "*", i, "=", n*i)


Using While Loop
i = 1
num = 7
while i <=10:
if i == 5:
i+=1
continue
print(num, "*", i, "=", num*i)
i+=1

[gulabalam]

#Factorial Using While Loop
n = int(input("Enter Number which to be factorial: ")) i=1
while_fact = 1
while i <=n:
while_fact*=i
i+=1
print(f"Factorial of {n} is:", while_fact)

[Airman.programer]

numb = 5
factorial = 1

# while numb > 0:
# factorial = factorial * numb
# numb = numb -1
# print(factorial)

for i in range(numb):
factorial = factorial * (i+1)
print(factorial)

[AmitKumar-mwjn]

Question: 7-
while True:
number=int(input("please enter the number between 1 and 10 :"))
if 1<=number<=10:
print("thanks")
break
else:
print("Invalid number, please enter the valid number")

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.
