Manually raising (throwing) an exception in Python. The few terms of the simplest Fibonacci series are 1, 1, 2, 3, 5, 8, 13 and so on. Within the while loop we have If statement and the condition if (2 <= 1) is FALSE so statements inside the else block will start executing, Next, Print statement print(Next) will print the value 1. NOTE: For Recursive functions it is very important to place a condition before using the function recursively otherwise, we will end up in infinite execution (Same like infinite Loop). # Fibonacci series will start at 0 and travel upto below number If it is TRUE, function will return the value Zero. # Recursive Function Beginning How to get nth result from simple function in python? Fibonacci sequence: A Fibonacci sequence is a sequence of integers which first two terms are 0 and 1 and all other terms of the sequence are obtained by adding their preceding two numbers. – iAdjunct Jan 12 '19 at 20:24 This type of series is generated using looping statement.
