how to create fibonacci sequence in python

def fib(n):
    a = 0
    b = 1

    print(a)    
    print(b)

    for i in range(2, n):
        print(a+b)
        a, b = b, a + b

fib(7) #first seven nubers of Fibonacci sequence

#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

startNumber = int(raw_input("Enter the start number here "))
endNumber = int(raw_input("Enter the end number here "))

def fib(n):
    if n < 2:
        return n
    return fib(n-2) + fib(n-1)

print map(fib, range(startNumber, endNumber))
