Just try it and see what will happen
Answer:
Following are the answer to this question:
x=int(input("Enter number: "))#defining x variable that input value from user end
if x< 0:#defining if block that check x value is less then 0
while x<0:#defining while loop print up to the value
print(x)#print value
x+= 1#add values by 1
elif x>0:#defining elif block to check value x is greater than 0
while x>0:#defining while loop to print down to value
print(x)#print value
x-= 1#subtract value by 1
Output:
when input is a positive value
Enter number: 5
5
4
3
2
1
when input is a negative value
Enter number: -5
-5
-4
-3
-2
-1
Explanation:
- In the given python code, x variable is declared that input the value from the user end, in the next step if and elseif block is declared that calculates and prints its value.
- In the if block, it checks value is negative it uses the while loop to prints its values in the down to value form.
- In the elif block, it checks the positive it uses the while loop to prints its values into the up to values form.
