What is the purpose of a cache in a computer system?
a) To store frequently accessed data for faster retrieval
b) To provide additional storage space for files
c) To control the flow of data between the CPU and other hardware components
d) To protect the computer from malware attacks

For all students of Python, web Development and basic Computer Courses

We would like to inform you that our Class which was scheduled to be held on the first Saturday of the week has been postponed to Next Friday due to our Exams next week. We would like to tell you to study the lessons with your full attention and prepare for the exams.

Note: Please note that there will be classes for two consecutive days next Friday and Saturday.

We would like to inform you that our Class which was scheduled to be held on the first Friday of the week has been postponed to Next Saturday.

Tomorrow, we will have classes just like scheduled in the timetable. So students do prepare and come to class on time.
Have a nice time.

#WebDevlopment

Since We Are Lagging Behind In Our Lessons In Website Development, please practice the codes I sent you above on your phone in the format you learned before. In our next class we will be talking about lists and Tables. Let’s practice the preliminary codes we’ll be looking at together under this topic.

Hello students

Due to different reasons we haven't learned for more than 3 weeks,
Please manage you're time as we might have multiple long learning sessions ahead to finish the course in this semester.

Hello, students
Due to some reasons our today's session is postponed for tomorrow.
We'll have a long session tomorrow starting from 2:00 - 6:00.
Make your self ready for the tomorrow's learning session.

Today is a Crucial Lesson so Missing class today may cost you dearly.

2:00 (Local Time)

#Basic_Computer


For basic computer students our class is in the afternoon 7:30 -9:00 local time. Don't miss it.

five examples for each type of loop in Python:

1\. For Loop:

# Example 1: Iterating over a string
for letter in "Python":
    print(letter)

# Example 2: Iterating over a tuple
fruits = ("apple", "banana", "cherry")
for fruit in fruits:
    print(fruit)

# Example 3: Iterating over a dictionary
person = {"name": "John", "age": 30, "country": "USA"}
for key, value in person.items():
    print(key, value)

# Example 4: Iterating over a list of numbers and finding the sum
numbers = [1, 2, 3, 4, 5]
sum = 0
for num in numbers:
    sum += num
print("The sum is:", sum)

# Example 5: Iterating over a list and printing the index and value of each element
fruits = ["apple", "banana", "cherry"]
for index, fruit in enumerate(fruits):
    print(index, fruit)

2\. While Loop:

# Example 1: Printing numbers from 1 to 10 using while loop
num = 1
while num <= 10:
    print(num)
    num += 1

# Example 2: Finding the factorial of a number using while loop
num = 5
factorial = 1
while num > 0:
    factorial *= num
    num -= 1
print("The factorial is:", factorial)

# Example 3: Removing all occurrences of an element from a list using while loop
numbers = [1, 2, 3, 2, 4, 2, 5]
element = 2
while element in numbers:
    numbers.remove(element)
print("The list after removing all occurrences of", element, "is:", numbers)

# Example 4: Printing numbers in reverse order using while loop
num = 10
while num >= 1:
    print(num)
    num -= 1

# Example 5: Finding the sum of digits of a number using while loop
num = 12345
sum = 0
while num > 0:
    digit = num % 10
    sum += digit
    num //= 10
print("The sum of digits is:", sum)

3\. Nested Loops:

# Example 1: Printing multiplication table using nested loops
for i in range(1, 11):
    for j in range(1, 11):
        print(i, "*", j, "=", i*j)
    print()

# Example 2: Finding all pairs of elements from two lists whose sum is even using nested loops
list1 = [1, 2, 3]
list2 = [4, 5, 6]
for x in list1:
    for y in list2:
        if (x+y) % 2 == 0:
            print("(", x, ",", y, ")")

# Example 3: Printing a pattern using nested loops
for i in range(1, 6):
    for j in range(1, i+1):
        print("*", end="")
    print()

# Example 4: Finding the common elements between two lists using nested loops
list1 = [1, 2, 3, 4]
list2 = [3, 4, 5, 6]
common = []
for x in list1:
    for y in list2:
        if x == y:
            common.append(x)
print("The common elements are:", common)

# Example 5: Printing all possible combinations of a list using nested loops
list1 = [1, 2, 3]
for i in range(len(list1)):
    for j in range(i+1, len(list1)):
        print("(", list1[i], ",", list1[j], ")")

4\. Range Loop:

# Example 1: Printing even numbers using range loop
for num in range(0, 11, 2):
    print(num)

# Example 2: Printing odd numbers using range loop
for num in range(1, 10, 2):
    print(num)

# Example 3: Printing numbers in reverse order using range loop
for num in range(10, 0, -1):
    print(num)

# Example 4: Finding the sum of numbers using range loop
numbers = [1, 2, 3, 4, 5]
sum = 0
for num in range(len(numbers)):
    sum += numbers[num]
print("The sum is:", sum)

# Example 5: Printing the ASCII values of characters using range loop
for char in range(ord('a'), ord('z')+1):
    print(chr(char), "=", char)

5\. List Comprehension:
`
# Example 1: Squaring numbers using list comprehension
numbers = [1, 2, 3, 4, 5]
squares = [num**2 for num in numbers]
print("The squares are:", squares)

# Example 2: Filtering even numbers using list comprehension
numbers = [1, 2, 3, 4, 5]
even = [num for num in numbers if num % 2 == 0]
print("The even numbers are:", even)

# Example 3: Removing duplicates from a list using list comprehension
numbers = [1, 2, 3, 2, 4, 2, 5]
unique = list(set([num for num in numbers]))
print("The list after removing duplicates is:", unique)

# Example 4: Converting a list of strings to uppercase using list comprehension
fruits = ["apple", "banana", "cherry"]
uppercase = [fruit.upper() for fruit in fruits]
print("The fruits i
