Question

Consider the following code: va1 = 0 while (val < 10): va1 = va1 - 1 print (val) What is the error?

Answer 1

The error in the given code is that the variable 'val' is not defined. To fix this error, the variable 'val' should be initialized and assigned a value before the while loop.

Step-by-step explanation:

The error in the given code is that the variable 'val' is not defined, which leads to a NameError. To fix this error, the variable 'val' should be initialized and assigned a value before the while loop. For example, if we want the loop to run until 'val' reaches 10, we can initialize it to 0 before the loop starts:

val = 0
while (val < 10):
val = val - 1
print(val)

In this modified code, 'val' starts at 0 and decreases by 1 in each iteration until it reaches 10. The 'print(val)' statement will then output the values of 'val' in each iteration.
