• round(.4) = 0

• round(-.5) = -0 (which is the same as 0)

Therefore, round(.4) - round(-.5) = 0 - 0 = 0

Explanation of round

Here are some examples to help you understand:

1. Positive Numbers:

• round(3.4) = 3 (because 3.4 is closer to 3)

• round(3.6) = 4 (because 3.6 is closer to 4)

• round(3.5) = 4 (special case - rounds to the nearest even number)

1. Negative Numbers:

• round(-3.4) = -3

• round(-3.6) = -4

• round(-3.5) = -4 (again, rounds to the nearest even number)

Basic rules:

• If the decimal part is less than .5, it rounds down

• If the decimal part is .5 or greater, it rounds up

• For .5 exactly, it rounds to the nearest even number

print ("Hello" + input ("What is your name? \n"))

There's an error in this code because len() is a function used to determine the length of sequences like strings, lists, or tuples, but it cannot be directly used with an integer.

When you try to use len() with an integer like 123455, Python raises a TypeError. This is because len() expects an object that has a length (such as a string, list, tuple, dictionary, etc.), but an integer does not have a length.

If you want to find the number of digits in an integer, you can convert it to a string first:

print(len(str(123456))) # This will print 6

=

print (len ("123456"))

<class 'int'>

<class 'str'>

<class 'bool’>

print ("eyad"+ str(5) )

OR

OR

print ("eyad" , 5 )

Example

print(f"eyad {5}") #Output: eyad 5

print(f"eyad{5}") #Output: eyad5

1. meaning that variable names, function names, and keywords must be written with the exact same capitalization. For example, print and Print are considered two different identifiers in Python.

2. is an interpreted language, as code is executed line by line.

3. code can run on different platforms (e.g., Windows, macOS, Linux) without modification.

Let’s break this down step by step:

Code:

a = 2 b = 3 print(a, b) a, b = b, a print(a, b)

Step 1: Initial Values

• a = 2

• b = 3

The first print(a, b) will display:

2 3

Step 3: After the Swap

The second print(a, b) will display:

3 2

Explanation of Swapping:

The line a, b = b, a uses tuple unpacking to swap values in a single step. This is a concise and Pythonic way to exchange the values of two variables without needing a temporary variable.

1. banana

2. apple

   orange

   banana

   coconut

   f

   r

   u

   i

   t

   s

   
   

3. False

   you can use the in operator to find if a value is within a list

4. ['orange', 'banana', 'coconut', 'pineapple']

   to add an element to the end of a list use the append method

   to remove an element you can use the remove method

5. ['pineapple', 'apple', 'orange', 'banana', 'coconut']

6. ['apple', 'banana', 'coconut', 'orange']

   the sort method will sort a list fruits.sort

   these are all in alphabetical order now apple banana coconut orange

7. ['coconut', 'banana', 'orange', 'apple']

8. []

def square(q):

return q * q # Takes a number q and returns q multiplied by itself

X = int(input("Enter a number: ")) # Convert input to an integer

print(square(X))

Very important ⚜️⚜️

Why you should add int before input ("Enter a number: “)

Explanation

The line r = lambda q: q * 2 creates a small function that we're storing in the variable r. Let's break down each part:

lambda is a special keyword that tells Python "I'm creating a quick, simple function"

q is the parameter name (like a variable that will hold whatever input we give the function)

The colon : separates the parameter from what the function will do

q * 2 is the operation - it takes whatever value is in q and multiplies it by 2

4.5 / 3 # Regular division: gives us 1.5

4.5 // 3 # Floor division: gives us 1

5.5 // 3 # Floor division: gives us 1

6.0 // 3 # Floor division: gives us 2

Explanation

The condition a or b and c is evaluated with the following precedence rules:

1. and has higher precedence than or, so b and c is evaluated first.

b and c is False and False, which results in False.

2. Now, the condition becomes a or False, which is True or False.

3. Since a is True, the entire condition evaluates to True.

Therefore, the if block is executed, printing "CAREERBODHSANSTHAN".

Explanation

What capitalize() does:

It only changes the first character of the string to uppercase (if it’s a letter).

It converts all other characters in the string to lowercase.

After removing first element: [20, 30, 40, 50]

After removing last element: [20, 30, 40]

In programming, mutable means that an object can be changed after it is created. In Python, the two core types that are considered mutable are lists and dictionaries.

def is_prime(n):

# If number is less than 2, it's not prime

if n < 2:

return False

# Check if number is divisible by anything up to its square root

for i in range(2, int(n ** 0.5) + 1):

if n % i == 0:

return False

return True

# Create an empty list to store prime numbers

prime_numbers = []

# Loop through numbers 1 to 1000

for num in range(1, 1001):

# If the number is prime, add it to our list

if is_prime(num):

prime_numbers.append(num)

# Print the list of prime numbers

print(prime_numbers)
