# 1. Introduction

Printing a sequence of numbers typically involves using iterative structures like loops. However, in Python, it's possible to print a sequence of numbers without utilizing loops, by using recursion or built-in functions that can iterate internally. This can be a fun and educational exercise in thinking about alternative ways to achieve common tasks.

Recursion is a programming technique where a function calls itself to perform a task. This can replace loops for tasks like printing numbers, by calling the function repeatedly with different arguments until a base case is reached.

# 2. Program Steps

1. Define the starting and ending values for the sequence of numbers to print.

2. Create a recursive function that prints the current number and calls itself with the next number.

3. Implement a base case in the function to stop the recursion when the end of the sequence is reached.

4. Call the recursive function with the starting number.

# 3. Code Program

```
# Recursive function to print numbers from start to end
def print_numbers_recursively(start, end):
# Print the current number
print(start, end=' ')
# Base case: if start is less than end, call the function with the next number
if start < end:
print_numbers_recursively(start + 1, end)
# Starting and ending values
start_value = 1
end_value = 10
# Call the recursive function to print the numbers
print_numbers_recursively(start_value, end_value)
```

### Output:

1 2 3 4 5 6 7 8 9 10

### Explanation:

1. *print_numbers_recursively* is a function that takes two arguments, *start* and *end*, which define the range of numbers to print.

2. The function prints the *start* value, followed by a space for separation.

3. The base case for the recursion is checking if *start* is less than *end*.

4. If the base case is *True*, the function calls itself with *start + 1*, incrementing the number to print.

5. The recursion continues until *start* equals *end*, at which point the recursion stops, as the base case is no longer true.

6. Initially, *print_numbers_recursively* is called with *start_value* set to 1 and *end_value* set to 10.

7. The output shows the numbers from 1 to 10 printed on the same line, demonstrating recursion's ability to handle iteration tasks without explicit loops.
