I want to print the sequence in line with the format …How?

Question

okay, I’ve figured out how to make the sequence result in one line, now I have to add a str…

here is the expected output:

Enter n: 10

Fibonacci numbers = 1 1 2 3 5 8 13 21 34 55

here is my code:

n = input("Enter n: ")

def fib(n):
    cur = 1
    old = 1
    i = 1
    while (i < n):
        cur, old, i = cur+old, cur, i+1
    return cur

for i in range(10):
    print("Fibonacci numbers = ")
    print(fib(i), end=" ")

here is the output that I want to fix:

Enter n: 10

Fibonacci numbers = 1 Fibonacci numbers = 1 Fibonacci numbers = 2 Fibonacci numbers = 3 Fibonacci numbers = 5 Fibonacci numbers = 8 Fibonacci numbers = 13 Fibonacci numbers = 21 Fibonacci numbers = 34 Fibonacci numbers = 55

I’m still learning python independently, Thank you to those who’ll take time to answer..

Answer 1

n = input("Enter n: ")

def fib(n):
    cur = 1
    old = 1
    i = 1
    while (i < n):
        cur, old, i = cur+old, cur, i+1
    return cur

print("Fibonacci numbers:")
fib_list = list()
for i in range(int(n)):
    fib_list.append(str(fib(i)))

print(' '.join(fib_list))

If you don’t want "Fibonacci numbers: " to print out on each loop iteration, remove it from the loop body.

print("Fibonacci numbers = ")

for i in range(10):
    print(fib(i), end=" ")

To do the least calculation, it is more efficient to have a fib function generate a list of the first n Fibonacci numbers.

def fib(n):
  fibs = [0, 1]
  for _ in range(n-2):
    fibs.append(sum(fibs[-2:]))
  return fibs

We know the first two Fibonacci numbers are 0 and 1. For the remaining count we can add the sum of the last two numbers to the list.

>>> fib(10)
[0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

You can now:

print('Fibonacci numbers = ', end='')
print(*fib(10), sep=' ', end='n')
