Python Function to Display Fibonacci Sequence given specific number of item counts

FibonacciSequence.py

# Function to create Fibonacci Sequence given that the user defines number of values

# First, use the "def" keyword to define the function

def fibonacciSequence():
    # Next, asking users to state the proportion or number of sequence terms to generate
    
    numberOfTerms = int(input("Hi, enter number of terms to for the Sequence: "))
    
    # Defining the first two terms that are mandatory    
    # Normally, 0 and 1 are the first and second terms of the series, hence:

    firstNum = 0
    secondNum = 1
    count = 0
    # Ensuring the user enters valid inputs, i.e., Fibonacci sequence starts from 0
    if (numberOfTerms <= 0):
        print("Invalid entry, please enter value more than 0")

    elif(numberOfTerms == 1):
            print("Generating Fibonacci Sequence upto ", numberOfTerms, ": ")
            print(firstNum)
            
    # For all other cases, i.e., when NumberOfTerms > 1
    else:
        print("Generating Fibonacci sequence upto ", numberOfTerms, ": ")
        while count < numberOfTerms:
            print(firstNum)
            nthNumber = firstNum + secondNum
        
        #  Swapping the values for firstNum and secondNum
            firstNum = secondNum
            secondNum = nthNumber
            count += 1

# Call the function
