I am trying write a code which generates a series of responses: if the user enters 1 number, several numbers or a string instead in order to generate a list of Fibonacci numbers. The code is as follows:
def fib (a, b):
return a + b
number = int(input("Please write how many Fibonacci numbers you wish to have generated: "))
fibonacci_list = []
for n in range(number):
if n in [0, 1]:
fibonacci_list += [1]
print("The first", number, "Fibonacci number is:", fibonacci_list)
elif:
fibonacci_list += [fib(fibonacci_list[n-2], fibonacci_list[n-1])]
print("The first", number, "Fibonacci numbers are:", fibonacci_list)
else:
print('Sorry could not recognise the input')
You should write a condition for elif too, for example:
elif n in [1,2]:
In your case, i would write the code in this way:
def fib (a, b):
return a + b
try:
number = int(input("Please write how many Fibonacci numbers you wish to have generated: "))
fibonacci_list = []
for n in range(number):
if n in [0, 1]:
fibonacci_list += [1]
print("The first", number, "Fibonacci number is:", fibonacci_list)
else:
fibonacci_list += [fib(fibonacci_list[n-2], fibonacci_list[n-1])]
print("The first", number, "Fibonacci numbers are:", fibonacci_list)
except:
print('Sorry could not recognise the input')
