In Python programming, the “assert” statement stands as a flag for code correctness, a vigilant guardian against errors that may lurk within your scripts.”assert” is a Python keyword that evaluates a specified condition, ensuring that it holds true as your program runs. When the condition i...
How to Fix It: If a syntax error appears, check to make sure that the parentheses are matched up correctly. If one end is missing or lined up incorrectly, then type in the correction and check to make sure that the code can be compiled. Keeping the code as organized as possible also...
