how to create fibonacci sequence in python
#Python program to generate Fibonacci series until 'n' value
n = int(input("Enter the value of 'n': "))
a = 0
b = 1
sum = 0
count = 1
print("Fibonacci Series: ", end = " ")
while(count <= n):
print(sum, end = " ")
count += 1
a = b
b = sum
sum = a + bPython Program for How to check if a given number is Fibonacci number?
# python program to check if x is a perfect square
import math
# A utility function that returns true if x is perfect square
def isPerfectSquare(x):
s = int(math.sqrt(x))
return s*s == x
# Returns true if n is a Fibinacci Number, else false
def isFibonacci(n):
# n is Fibinacci if one of 5*n*n + 4 or 5*n*n - 4 or both
# is a perferct square
return isPerfectSquare(5*n*n + 4) or isPerfectSquare(5*n*n - 4)
# A utility function to test above functions
for i in range(1,11):
if (isFibonacci(i) == True):
print i,"is a Fibonacci Number"
else:
print i,"is a not Fibonacci Number "Copyright © 2021 Codeinu
