-There are (at least) two distinguishable kinds of errors in Python: syntax errors and exceptions.
+The two types of **errors** in Python are syntax errors and exceptions.
 
 ## Syntax Errors
 
-Syntax errors, also known as parsing errors, are perhaps the most common kind of complaint you get while you are still learning Python:
+Syntax errors (also known as parsing errors) occur when a sequence of characters, or tokens, violates the syntax of the Python programming language:

 The parser repeats the offending line and displays a little arrow `^` pointing at the earliest point in the line where the error was detected.
 
-The error is caused by (or at least detected at) the token preceding the arrow in the example, the error is detected at the function `print()`, since a colon `:` is missing before it.

+File name and line number are printed to state where the error originated.
 
 ## Exceptions
 
 Even if a statement or expression is syntactically correct, it may cause an error when an attempt is made to execute it. Errors detected during execution are called exceptions and are not unconditionally fatal. Most exceptions are not handled by programs, however, and result in error messages as shown here:
