You can easily check where the indentation error occurred by checking the error log and seeing the line from where the error originated. Inside the ‘if’ statement, everything must be further indented. Inside ‘for’ loop, we have an ‘if’ statement. Everything inside the ‘for’ loop must be indented. The mixing of two will cause issues.Ĭorrect indentation is shown in the example above. If you are using spaces, always use spaces and if you are using tabs, always use tabs. Make sure that your indentation is consistent. See that the indentation for a specific block remains the same throughout the code even if a new block is introduced in the middle. Block structure visualizing indentationĬheck out the diagram above. If there is an ‘If’ statement, there needs to be an indentation to the code which follows it. There are several blocks in code with respect to the structure. Since the code is yours, you have to go through each line and see where you made the mistake. Solution 1: Checking for wrong white spaces/tabs

You forgot to indent user-defined functions or classes.

You forgot to indent the compound statements such as ‘if’, ‘for’, ‘while’ etc.

If the indentation practice is not followed, you will have this error inevitably. If both are used interchangeably, the interpreter will not be able to determine which item to use.

You are using both spaces and tabs in your code.

The program may run properly but if the interpreter finds this error, the error message will come forth in the middle. Since Python uses procedural language, you may experience this error if you have not placed the tabs/spaces correctly.

Like mentioned before, this error primarily occurs because there are space or tab errors in your code. It is ideal for every programmer to use proper indentations so code readability improves. Since Python arranges all of its code by correct whitespaces, if you have a bad indentation, the code will not compile and you will be returned an error message.Īccording to the conventions followed in PEP8, there should be four whitespaces where required. The ‘ Indentation Error: Expected an indented block’ occurs for all sorts of users whether they are newbies or experienced.

The language is known for its large comprehensive library and supports several programming paradigms such as functional, imperative, procedural, and object-oriented. Python is an emerging programming language which was first released in 1991.
