Condition for Range and Recursive Function in Python
Range: It is used to generate a sequence of numbers, commonly used in for-loops to iterate over a specific range of values.
Recursive function: It solves a problem by solving smaller instances of the same problem, with a base case to stop the recursion.
Step-by-Step Process
Range: It generates a sequence of numbers, starting from start (default 0) to stop (exclusive),with an optional step value (default 1).It returns an immutable sequence (iterator), which is memory efficient.
Recursive function: A function that calls itself .
Base Case: The condition that stops the recursion and prevents it from running indefinitely.
Recursive Case: The part of the function where it calls itself with modified arguments to solve smaller subproblems.
Sample Code
#Range
print("Output for range:")
for i in range(3):
print(i)
print()
print("Output for range with step value:")
# Using range with start, stop, and step
for i in range(1, 10, 2):
print(i)
print()
#Recursion
print("Output for recursion:")
def sum_of_numbers(n):
if n == 1:
return 1
else:
return n + sum_of_numbers(n - 1)
result = sum_of_numbers(5)
print(result)
