One way to get around this kind of error is to use automatic code formatters based on PEP8 standards, like autopep8 or Black. You need one more space, then the code will run: a = 1 This line doesn’t belong to any of the existing indentation levels.
When the lines are drawn, it becomes obvious that the indentation is not in line with the print statement. The first line has a tab and the second has 4 spaces, which is an entirely different level of indentation for a Python interpreter: print("Hello")įor this error, you can either remove or replace all of the indents, or enable service characters, in Notepad++ this looks like this: This error is the hardest to figure out because it looks like the code’s on the same line. Since using different numbers of indentations can be confusing, PEP8 recommends exactly four spaces per level of indentation: a = -1Īnother copying error can happen when you edit your code in a text editor without the ability to replace tabs with 4 spaces, such as Notepad++, and use both tabs and spaces for indentation. Python uses spaces for indentation, and tabs are automatically converted to four spaces in Python 3 editors.Īnother feature is that the number of indent spaces can be any, but inside the block they’re the same. Just indent a block that’s inside a loop or other appropriate construction. IndentationError: expected an indented block happens when you start a construct that assumes you have at least one indented block, but you didn’t indent this. IndentationError: expected an indented block You’ll get a similar error if you don’t indent after a keyword, here’s an example: for _ in range(10):

How to Solve IndentationError: unexpected indent error in Python Python warns you if it finds a line that’s indented, but the previous line doesn’t have these keywords.
One of the key features of this beauty is the lack of curly braces and other symbols that mark the beginning and end of each block.Įven in C it is considered a good practice to indent, denoting different levels in the code. Let’s kick things off with error #1! How to Solve IndentationError: unexpected indent in Python So if you want to learn how to solve those errors, then you’re in the right place. IndentationError: unindent does not match any outer indentation level.IndentationError: expected an indented block.You’ll learn what these errors mean and how to solve them: Python indentation is a part of the syntax.
