Program to print first n fibonacci numbers in python
The python program to print fibonacci series using while loop is as follows:
# Owner : TutorialsInhand Author : Devjeet Roy
number = int(input("Enter upper limit: "))
a = 0
b = 1
sum_fib = 0
print(a,b, end=" ")
while True:
sum_fib = a + b
a = b
b = sum_fib
if sum_fib < number:
print(sum_fib, end=" ")
else:
break
The output of the python program to print fibonacci numbers is as follows:
PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py En
Enter upper limit: 20
0 1 1 2 3 5 8 13
PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter upper limit: 24
0 1 1 2 3 5 8 13 21
Few important tips about the program
1. The fibonacci series is such a series which begins with 0 and 1 and the rest of the terms are the sums of their previous two terms.
2. Here, the user has given an upper limit which we have converted to int data type.
3. Thereafter, we found the sum of two numbers and we have assigned the second number to first number, the sum of the two numbers to the second number.
4. We printed the sum out, if it is lesser than the upper limit.
