While Loop

Q1.

num=int(input("num: "))
sum=0
while num>0:
	if num%2==0:
		sum+=num
	num-=1
print("sum:",sum)

Q2.

# Python program to find the sum of integers between 0 and n where n is provided by user
num=int(input("num: "))
sum=0
if (num>0):
	while(num>=0):
		sum=sum+num
		num-=1
else:
	while num<0:
		sum=sum+num
		num+=1
print("sum:",sum)

Q3.

x=int(input("x: "))
y=int(input("y: "))
i=1
if x!=0 and y!=0:
	while(y>0):
		rem=y%x
		x=y
		y=rem
	print("gcd:",x)
else:
	print("value must be non zero")

Q4.

# Write your code here
x=int(input("k: "))
a=0
b=1
i=0
sum1=0
while(a<x):
	print(a)
	if i%2==0:
		sum1=sum1+a
	next_term=a+b
	a=b
	b=next_term
	i+=1
print("sum:",sum1)

Q5.

x=int(input("k: "))
y=0 
while y<x:
	if y%2==0:
		print(y,"even number")
	else:
		print(y,"odd number")
	y+=1
