### Basic Questions

1: Write a Python program that prints the string “Hello, World!” to the console.

```# INPUT:
Not required

# OUTPUT:
Hello, World!
```

2: Write a Python program that takes two integers as input and prints their sum to the console. ```# INPUT:
5
7

# OUTPUT:
12```

3: Write a Python program that prints a list of numbers from 1 to 10, separated by commas.

```# INPUT:
no input

# OUTPUT:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
```

4: Write a Python program that prints a multiplication table for a given number. For example, if the input is 3, the output should be:

```3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
...
3 x 10 = 30```

5: Write a Python program that prints the following text to the console, using only one `print()` statement:

```*****
***
*```

### Intermediate Questions:

6: Write a Python program that takes a list of strings as input and prints them to the console, each on a separate line, using the `sep` and `end` arguments to customize the output. Sample Input/Output:

```#Input:
["apple", "banana", "orange"]

#output:
apple
banana
orange
```

7: Write a Python program that takes a list of integers as input and prints them to the console, separated by commas, and with a custom message before and after the list, using the `sep` and `end` arguments. Sample Input/Output below:

```#INPUT:
[1, 2, 3, 4, 5]

#OUTPUT:
The numbers are: 1, 2, 3, 4, 5.
```

8: Write a Python program that takes a list of strings as input, and prints the strings to the console, separated by a forward slash (`/`), and each string enclosed in double quotes.

```#INPUT:
["apple", "banana", "cherry"]

#OUTPUT:
"apple"/"banana"/"cherry"```

9: Write a Python program that prints the following text to the console, using only one `print()` statement and separating each word by a semicolon (`;`), but the last word should end with a colon (`:`).

```#INPUT:
No input required

#OUTPUT:
apple;banana;cherry:```

10: Write a Python program that prints the following text to a file named “output.txt”:

```Hello, World!
This is a test file.

#OUTPUT:
The text should be printed to a file named "output.txt".
```

11: Write a Python program that takes a list of integers as input, and prints the integers to a file named “output.txt”, separated by commas (`,`) and spaces.

```#Sample input:
[1, 2, 3, 4, 5]

#Sample output:
The integers should be printed to a file named "output.txt" in the following format: 1, 2, 3, 4, 5```

12: Write a Python program that takes a dictionary as input, and prints the key-value pairs to a file named “output.txt” in the following format:

```key1: value1
key2: value2
key3: value3

#Sample input:
{"key1": "value1", "key2": "value2", "key3": "value3"}

#Sample output:
The key-value pairs should be printed to a file named "output.txt" in the above format.```

13: Write a Python program that reads a file named “input.txt”, replaces all occurrences of the word “apple” with “orange”, and prints the modified text to a file named “output.txt”.

Sample input (in “input.txt” file):

```I like apple pie.
Do you like apples?
```

Sample output (in “output.txt” file):

```I like orange pie.
Do you like oranges?
```

14: Write a Python program that prints the numbers 1 through 10 to the console, one number per line, and flushes the output after each number is printed.

```#Sample input:
No input required

#Sample output:
The numbers 1 through 10 should be printed to the console, one number per line, with no delay between the numbers.```

15: Write a Python program that takes a list of strings as input, and prints each string to the console with a delay of 1 second between each string. The program should flush the output after each string is printed.

```#Sample input:
["apple", "banana", "cherry"]

#Sample output:
The strings "apple", "banana", and "cherry" should be printed to the console with a delay of 1 second between each string. The output should be immediately flushed after each string is printed.```

16: Write a Python program that simulates the progress of a task by printing a series of dots to the console, one dot per second, until the task is complete. The program should flush the output after each dot is printed.

```#Sample input:
No Input required

#Sample output:
The dots should be printed to the console, one dot per second, until the task is complete.```

17: Write a Python program that takes a list of integers as input, and prints the running total of the integers to the console, with a delay of 1 second between each total. The program should flush the output after each total is printed.

```#Sample input:
[1, 2, 3, 4, 5]

#Sample output:
The running total of the integers should be printed to the console, with a delay of 1 second between each total. The output should be immediately flushed after each total is printed.```

18: Write a Python program that takes a list of numbers as input and prints them to the console, with the even numbers in blue and the odd numbers in red, using ANSI escape codes and the `flush` argument to ensure the colors are applied correctly. Hint: Ansi Escape Codes
