Using incorrect indentation inside loops
Python relies heavily on indentation to define blocks of code. Unlike other languages that use {} (curly braces), Python uses whitespace (spaces or tabs) to determine where a block of….
Overwriting built-in functions
Python provides a rich set of built-in functions like sum(), max(), min(), list(), dict(), print(), and many more. These functions are essential for performing fundamental operations. However, accidentally overwriting built-in….
Using “is” instead of “==” for value comparison
Python provides two different operators for comparison: Using is instead of == for value comparison can lead to incorrect behavior, especially when working with strings, numbers, lists, and other mutable….
Using “==” instead of “is” for comparison
Python provides two different operators for comparison: Misusing is and == can lead to logical errors that may be difficult to detect. Let’s explore this issue step by step. 1…..
Misuse of mutable default arguments
Default arguments in Python functions allow parameters to have pre-defined values. However, using mutable objects (such as lists, dictionaries, or sets) as default arguments can cause unintended side effects. This….
SyntaxError: unexpected EOF while parsing
The error “SyntaxError: unexpected EOF while parsing” occurs when Python reaches the end of the file (EOF) but expects more code to complete a statement. This happens when an expression….
SyntaxError: EOL while scanning string literal
The error “SyntaxError: EOL while scanning string literal” occurs when Python reaches the end of a line (EOL) while parsing a string but does not find a proper closing quotation….
SyntaxError: invalid syntax
A SyntaxError in Python occurs when the interpreter encounters code that does not follow Python’s syntax rules. The error message “SyntaxError: invalid syntax” means that Python cannot understand and execute….
