# The provided code snippets demonstrate several programming techniques in
# Python, including loops, user inputs, and generating specific text patterns.
# Below, I'll explain each part of the code:

# 1. **For Loops with Names:**
# - A list named `names` is created containing four names.
# - The type of the `names` list is printed, confirming it's a list.
# - The list is printed, showing all names.
# - The second name in the list is printed using its index.
# - A `for` loop iterates through each name in the list to greet each one with
# "Hello!".
  
# Here’s the code snippet:
# ```python
# names = ["Josiah", "Oren", "Ezra", "Sohail"]
# print(type(names))
# print(names)
# print(names[1])
# for name in names:
# print("Hello, ", name, "!")
# ```

# 2. **Simple Countdown Timer:**
# - A countdown from 10 to 1 is performed using a `for` loop with a range that
# decreases.
# - Each number is printed one at a time, and there’s a 1-second delay between
# each print using `time.sleep(1)`.
# - After the countdown, it prints "Liftoff!".
  
# Here’s the code snippet:
# ```python
# import time

# for num in range(10, 0, -1):
# print(num)
# time.sleep(1)  # Adding a delay of 1 second between counts

# print("Liftoff!")
# ```

# 3. **Number Pyramid (Sequence 1):**
# - The user is prompted to input an integer.
# - A number pyramid is generated where each row contains a sequence of numbers
# starting from 1 up to the current row number, centered horizontally.
  
# Here’s the code snippet:
# ```python
# num = int(input("Enter an integer: "))

# for i in range(1, num + 1):
# print(' ' * (num - i) + ' '.join(str(x) for x in range(1, i + 1)))
# ```

# 4. **Number Pyramid (Sequence 2):**
# - Similar to the previous example, the user inputs an integer.
# - This program prints a series of lines where each line consists of the
# integer repeated as many times as the line number,

# Prompting user for an integer input
num = int(input("Enter an integer: "))

# Calculating the sum of all integers less than or equal to the user-provided
# integer
total_sum = sum(range(1, num + 1))

# Printing the result
print(f"The sum of digits is {total_sum}")

# Prompting user for an integer input and calculating the sum
total_sum = sum(range(1, int(input("Enter an integer: ")) + 1))

# Printing the result
print(f"The sum of digits is {total_sum}")

# Prompting user for a word input
word = input("Enter a word: ")

# Generating a string of every other letter starting from the second letter
result = word[1::2]

# Printing the result
print(result)

# The double colon `::` in the string slicing syntax is used to specify a step
# value in Python. It allows you to select elements in a sequence (like strings
# or lists) with a specific interval.

# For example, in the expression `word[1::2]`:

# - `1` is the starting index (inclusive), which means it starts from the second
# character of the string (the letter at index 1).
# - The second colon `:` indicates that we want to go to the end of the string.
# - `2` is the step value, which means we take every second character from the
# starting index.

# So, `word[1::2]` effectively returns every other letter in the string starting
# from the second letter.
