Python - Syntax Errors versus Exceptions
Syntax Errors Versus Exceptions in Python
Syntax errors and exceptions are the two primary types of problems that you can run into when creating code in Python. It is essential to comprehend their distinctions to troubleshoot and write reliable Python scripts, but they differ in the following ways:
definition
A syntax error is a mistake in code that prevents it from running correctly, while an exception is something normal or normally allowed
cause
Syntax errors occur when a programmer types something incorrectly, such as misspelling a word or using punctuation incorrectly. Exceptions can occur for several reasons, including incorrect user input, device failure, or a program attempting to divide by zero.
When they occur
Syntax errors occur during parsing or compiling code, while exceptions occur during program execution.
In summary, the main difference between syntax errors and exceptions is that syntax errors are detected by the compiler or interpreter before the code is executed, whereas exceptions occur during program execution.
Example
Here is an example to illustrate the syntax error v/s exceptions.
Syntax Error Example
In this example, the missing colon at the end of the if statement would result in a syntax error because it does not conform to the syntax rules of Python.
x = 10
if x > 5 # Missing colon at the end of the if statement
print("x is greater than 5")Exception example
In this example, trying to divide x by y, where y is 0, will raise a ZeroDivisionError exception when executing the function. This is not a syntax error, as the code is well written, but it causes an exception because dividing by zero doesn't work.
x = 10
y = 0
try:
# Division by zero will raise an exception
result = x / y
except ZeroDivisionError as e:
print("Error: Division by zero")
