What causes indentation error
It always pops up when I put two the same actions on the same row
From the SoloLearn's python tutorial: "Python uses indentation (white space at the beginning of a line) to delimit blocks of code. Other languages, such as C, use curly braces to accomplish this, but in Python indentation is mandatory; programs won't work without it. As you can see, the statements in the if should be indented." Basically you need indentation every time you make a block of code
Basically, if a line ends in a colon, the next line must be indented. If you post a link to the code you wrote, we can give you a better answer about why you are getting the error.
Be careful and don't mix spaces and tabs when you're doing indentation. A space followed by a tab May look like a single indentation but it's actually two levels of indentation. This has cause me some problems when combining different pieces of Python code. A good IDE he will help you fix it. even "idle" is good with Python indentation problems.
