If you write code on your phone like I do (using Termux, Acode, or other mobile editors), you have probably wanted to throw your phone across the room because of this error:
IndentationError: unexpected indent
Python is incredibly strict about spaces. But when you copy and paste code from the web into a mobile editor, the phone often adds hidden tabs or extra spaces, completely breaking your script.
Here is exactly how I fix it when I'm coding on the go.
1. The "Select All" Trick
If the code is a mess, highlight the entire block of code, delete it, and re-type the first line manually. Make sure your cursor is at the absolute far-left edge of the screen before you start typing. Mobile keyboards love to auto-indent the very first line, which ruins the whole block.
2. The Hidden Space Test
Move your cursor to the very beginning of the line that is throwing the error. Press the backspace key a few times. If the line suddenly jumps to the left, it means the editor had hidden spaces pushing the code too far to the right.
3. Turn Off Auto-Indent (If Possible)
Many mobile code editors try to "help" by auto-indenting when you press Enter. If you are writing a while loop, this is great. If you are copying and pasting, it causes chaos. Check your editor's settings and turn off "auto-indent" if you are pasting large chunks of code.
The Golden Rule
When typing Python manually:
· 4 spaces for a function or if statement.
· 8 spaces for the code inside the function.
• Never mix tabs and spaces. Choose spaces, always. (Most modern editors will let you set "Insert spaces instead of tabs").
If you get an IndentationError, don't panic. Look at the line above the error, find the hidden space, and backspace it.
