How to Fix the \'Unexpected Indent\' Error in Python?

Identifying the "Unexpected Indent" Error in Python

When dealing with Python code, the "unexpected indent" error can be encountered. This error arises due to improper indentation in your code.

Understanding Python's Indentation

Python uses indentation to define the scope of code blocks. Each block under an if, else, for, or while statement must start with an equal number of whitespaces from the left margin. Proper indentation ensures that the code flow is clear and unambiguous.

Rectifying the Error

To rectify this error, carefully check the indentation of the code block where the error is indicated. Ensure that all lines within a block are indented with the same number of spaces.

Common Indentation Issues

• Unexpected indent: This occurs when a line has more spaces than the line before it, but the previous line is not the start of a block.
• Unindent does not match any outer indentation level: This occurs when a line has fewer spaces than the line before it, and it doesn't match any valid indentation level.
• Expected an indented block: This occurs when a statement (e.g., if, while) expects an indented block after it, but the subsequent line does not start with the expected number of spaces.

Tips for Avoiding Indentation Errors

• Use an IDE that supports automatic indentation.
• Use a consistent number of spaces for each level of indentation.
• Avoid mixing tabs and spaces in indentation.
• Ensure that the indentation is the same for all lines within a block.
