# Assignment Fibonacci series # Thank You Sir. def fib(num): if(num

[@patelprit442]

why you take n+1 in for loop range

[@shilpakannan9058]

Cos if you want till num ,should take one number ahead to get that..for eg to get 24 we write 24+1 which gives till 24 value

[@hardikkumar5188]

I was actually learning from a Udemy video, but that was a bit confusing so I started to search on KZbin and I found this video. This video is extremely useful and helped me to understand the concept. Also, the use of visual representation makes things a lot more intuitive and easy. Thanks a lot Sir

Hi Navin, Your teaching is one of the best. You can only teach us the concept. It is our duty to play and try different approach. You have taught us every thing to create the following function. This function is memory efficient and you don't have to check for 0 or negative inputs. def fib(n): a=0 b=1 for i in range(0,n): print(a) a,b = b,a+b

issue with the condition for the loop. Here is a more comprehensible code def fib(x): a = 0 b = 1 if x==1: print("0") elif(x

[@yashsurana2554]

This is great but it will not work in the while loop as it will stop when a is lesser than x. So suppose I take x as 5, the output will be : 0 1 1 2 3 5 8 it will stop at 8 because 8(a) is less than 10(x). For this purpose, we must use for loop keeping x as a range input. a = 0 b = 1 x = 10 for i in range(x): print (a) a,b = b,a+b

[@RockstarBuddies]

When inputted 0, this code would not give 0 as an output so we could add if n == 1: print(c) after defining c and before starting the while loop. After this, we could even write elif n < 0: print('Invalid Input') so that it doesn't take negative numbers

Navin sir, This can also be done using for i in range (2,n): a, b=b, a+b Print (b) Therefore you will not have to use a third variable which will make the coding memory efficient 😀 Thanks, Your student.

[@shalemrobin6233]

Hi, Thank you for the code which will make coding memory efficient and I tried it and it did work. One more I want to ask, in for we all know that it won't run till n times for Fibonacci series for e.g. if n is 100 it loop will not run for 100 times, if it gets any value greater than 100, it will end, if we give n in range will it take more memory, if it will take memory space what would be alternative to do it.

Without going for if c>100 and adding a break at the end, you could have tried that at the top in the first if statement. if n100: If the input is : - 101 Output will be : - "Invalid input" That would have shortened your code. Keep up the good work!

For number less than 0: def fib(n): a = 0 b = 1 if n

[@suhailahmed7706]

n=int(input("enter the last value")) a=0 b=1 c=0 print(a,b) while c < n: c=a+b a=b b=c if c>=n: break print(c)

Total fibonacci series with no errors. Can play as many times as you want without running each time.(1st assignment) def fib(n): a = 0 b = 1 if n==1: print(a) else: print(a) print(b) for i in range(2,n): c = a+b a = b b = c print(c) a = 1 while a==1: n = input("Enter the number of sequences you want for fibonacci sequence:") try: n = int(n) except: print("String's can't be used with fibanacci series.") continue if n

for finding fibonacci numbers within input range: def fib(x): a = 0 b = 1 print(a) print(b) for i in range(2,x): c=a+b a=b b=c if c

#Fibonacci Sequence using functions def fib(n): a=0 b=1 if n==1: print(a) elif n n): break print(a) fib(150) Result will be 144

It should be print(c) in the inner if condition

I love how you involve viewers while coding, not just showing pre-written code.
