Question

d) Write a python program to print the Fibonacci series .

e) Write a python program to print table a given number

Answer 1

D)

## Fibonacci Series is a series of numbers in which each number is the sum of the two preceding numbers.

def fibonacci(n): # Defining a function.

   first,second=0,1 # The fibonacci started with 0 and 1.

   if n<=0: # If the value of n is less or equal to 0 then this will display a message "Invalid input".

       print("Invalid input.")

   elif n==1: # If the value of n is equal to 1, then it'll show only the first number as the next line is printing only the first variable.

       print(first)

   else: # Else it'll print All the values till n.

       print(first)

       print(second)

       for i in range(2,n):

           sum=first+second  # This will add the value of the first and second variables.

           print(sum)

           first,second=second,sum # this will swap the value of first and second with second and sum respectively. So that we can print the Fibonacci Series.

   #End of the Function.

           

n=int(input("Enter till how many numbers you want fibonacci series : ")) # This will ask the user the value of n.

fibonacci(n) # This will call the function fibonacci.

E)

a=int(input("Enter the number for which you want the table: ")) # Ask the user for which he/she wants the table.

b=int(input("Till how much do you want the table : ")) # Ask the user till how many values the user want the  table.

for i in range(1,b+1):  

 print(a,"*",i,"=",a*i) # this will prnt the table in the classical way I used learn tables. ;)

Answer 2

Answer:

d.)

#start of program

a = 0

b = 1

for i in range (0, 5):

   print(a)

   print(b)

   c = a + b

   print(c)

   a = b + c

   b = a + c

#end of program

e.)

#start of program

a = int(input("Enter the number whose table has to be printed: \n"))

for i in range(1, 11):

   print(a, "*", i, "=", a*i)

#end of program

Explanation:

d.)

Here we have the initial value of a as 0 and b as 1.

Then, we create a loop that will be executed 5 times (or as you wish).

The loop will first print the values of a and b and then store the sum of a and b in another variable c and print the value of c.

Then we store the sum of b and c, ie 1 + 1 in a and then store the value of sum of a and c, ie 2 + 1 in b.

The loop will be executed again and then the updated values of a and b will be printed.

e.)

In the second program, we input a number of integer data type and then print its table using the for loop, 10 times.
