Python Print parameter end

Question

How to remove the last \"add -->\" from the output when using end, i am not using sep here, bcoz sep will not have any effect here , as the print statement prints just 1 item at

Answer 1

you can use an if statement to check if its the last number:

def fibonaci_num(n):
    if n <= 1:
        return n
    else:
        return fibonaci_num(n-1) + fibonaci_num(n-2)

N = 10

for i in range(N):
    print(fibonaci_num(i), end='')
    if i != N-1:
        print(' add -> ', end='')

Answer 2

The inevitable pythonic one-liner:

print(*map(fibonaci_num, range(N)), sep=' add -> ')

Answer 3

Here I've simplified answer using ternary operator. May it will be helpful and better.

def fib(n):    
    a, b = 0, 1
    while a < n:
        endstatement = '-' if (b < n) else ''
        print(a, end=endstatement)
        a, b = b, a+b
    print()


# Now call the function:
fib(1000)

Result: 0-1-1-2-3-5-8-13-21-34-55-89-144-233-377-610-987
