Dif x > 0
print('Positive')
else
print('Non-positive')
Step-by-Step Solution
Solution:
Step 1: Recall Python if-else syntax
Python uses a colon after the condition and indentation for the code blocks.
Step 2: Check each option
if x > 0:
print('Positive')
else:
print('Non-positive') uses colons and indentation correctly. if x > 0 then print('Positive') else print('Non-positive') uses 'then' which is not Python syntax. if (x > 0) { print('Positive'); } else { print('Non-positive'); } uses braces and semicolons, which are for other languages. if x > 0
print('Positive')
else
print('Non-positive') misses colons and indentation.
Final Answer:
if x > 0:
print('Positive')
else:
print('Non-positive') -> Option A
