how to print the fibonacci sequence in python using while loop code example

Example 1: 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 + b

Example 2: fibonacci series in python

# Program to display the Fibonacci sequence up to n-th term

nterms = int(input("How many terms? "))

# first two terms
n1, n2 = 0, 1
count = 0

# check if the number of terms is valid
if nterms <= 0:
   print("Please enter a positive integer")
elif nterms == 1:
   print("Fibonacci sequence upto",nterms,":")
   print(n1)
else:
   print("Fibonacci sequence:")
   while count < nterms:
       print(n1)
       nth = n1 + n2
       # update values
       n1 = n2
       n2 = nth
       count += 1

Example 3: how to print the fibonacci sequence in python using while loop

#Learnprogramo
Number = int(input("How many terms? "))
# first two terms
First_Value, Second_Value = 0, 1
i = 0
if Number <= 0:
print("Please enter a positive integer")
elif Number == 1:
print("Fibonacci sequence upto",Number,":")
print(First_Value)
else:
print("Fibonacci sequence:")
while i < Number:
print(First_Value)
Next = First_Value + Second_Value
# update values
First_Value = Second_Value
Second_Value = Next
i += 1
