## Python 3 Script to Print the Fibonacci Series Sequence Using For and While Loop Full Tutorial For Beginners Welcome folks today in this blog post we will be building a `fibonacci` series sequence in python using for and while loop. All the full source code of the application is shown below.

# Get Started

In order to get started we need to make an `app.py` file and copy paste the following code

First of all we will be using the `while` loop to print the series

`app.py`

``````# Python Fibonacci series Program using While Loop

# Fibonacci series will start at 0 and travel upto below number
Number = int(input("\nPlease Enter the Range Number: "))

# Initializing First and Second Values of a Series
i = 0
First_Value = 0
Second_Value = 1

# Find & Displaying Fibonacci series
while(i < Number):
if(i <= 1):
Next = i
else:
Next = First_Value + Second_Value
First_Value = Second_Value
Second_Value = Next
print(Next)
i = i + 1``````

Now we can print the series by the `for` loop

`app.py`

``````# Python Fibonacci series Program using For Loop

# Fibonacci series will start at 0 and travel upto below number
Number = int(input("\nPlease Enter the Range Number: "))

# Initializing First and Second Values of a Series
First_Value = 0
Second_Value = 1

# Find & Displaying Fibonacci series
for Num in range(0, Number):
if(Num <= 1):
Next = Num
else:
Next = First_Value + Second_Value
First_Value = Second_Value
Second_Value = Next
print(Next)``````

Now if you execute the `python` script by typing the below command

`python app.py`
