What does the following code print?import mathx=100while(math.sqrt(x)>0): print("Square root larger than 0")x -= 5
Question
What does the following code print?
import math
x = 100
while (math.sqrt(x) > 0):
print("Square root larger than 0")
x -= 5
Solution
The code you provided has an infinite loop because the decrement of the variable x
is not inside the while loop. This means that the value of x
is never updated during the loop, so the condition math.sqrt(x) > 0
is always true. As a result, the program will print "Square root larger than 0" indefinitely.
However, if you intended to decrement x
within the loop, the corrected code should look like this:
import math
x = 100
while(math.sqrt(x) > 0):
print("Square root larger than 0")
x -= 5
In this case, the program will print "Square root larger than 0" as long as the square root of x
is greater than 0. The value of x
is decremented by 5 in each iteration. When x
becomes negative, math.sqrt(x)
will throw a ValueError
because math.sqrt() does not support negative numbers.
