Learning Python: The Ultimate Guide for Beginners to Coding with Python with Useful Tools

Forgetting to Indent
A for loop always require indentation; however, if you forget it, Python will remind you. save this
program with magic.py Let us look at the example below.
magicians_name =[“Greg,” “Perpetual,” “Amos”]
magician in magicians_name:
print(magician)
In this code, the third line should be indented but wasn’t. Once the Python interpreter encounters
such statement that should have an indented block but didn’t find any, it indicates an error with the
code as follows:
File “magic.py,” line 3
print(magician)
^
IndentationError: expected an indented block
To solve this error, you have to indent the line of code properly. As simple as this mistake may be,
it can keep you from getting an error each time you run a program.
Besides  forgetting  to  indent,  you  may  forget  to  indent  statements  in  a  loop.  Your  loop  may  run
successfully without any errors, but your output will be different from what you expected. When
this happens, it signifies you are doing several tasks inside your loop and didn’t indent some of the
lines of codes. For instance, you didn’t indent the second line in the magician code that says, “keep
