Answer:
Following are the code to this question:
def Fibonacci(n):#defining a method Fibonacci that accept a parameter
a = 1#defining a variable a that holds a value 1
b = 1#defining a variable b that holds a value 1
if n <= 0:# Use if to check n value
print("invalid number")#print message
elif n == 2:#defining elif that check n equal to 2
return 1#return 1
else:#defining else block
print(a)#print value of a
print(b)#print value of b
for i in range(2,n):#defining for loop to calculate series
s = a + b# add value in s variable
a = b # interchange value
b = s# hold s value
print(s)#print s value
Fibonacci(10)#calling method
Output:
1
1
2
3
5
8
13
21
34
55
Explanation:
In the above-given program code, a method "Fibonacci" is defined, which holds a value "n" in its parameter, and inside the method two-variable "a and b" is defined, that holds a value "1".
- In the next step, if a block is defined that checks n value is less than equal to 0, it will print "invalid number" as a message.
- In the elif, it checks n value is equal to 2 it will return a value that is 1.
- In the else block, it will calculate the Fibonacci series and print its value.
