how to solve "IndentationError: unexpected indent" error in Python?

The "IndentationError: unexpected indent" error in Python occurs when there is an indentation error in your code. In Python, indentation is used to indicate the beginning and end of blocks of code, such as loops and function definitions. If the indentation in your code is not consistent or does not follow the rules of Python's indentation, you may get an "unexpected indent" error.

Here's an example of code that might generate this error:

def my_function():
    print("Hello, world!")
      print("This line has too much indentation")

In this example, the second print statement has an extra space before it, which causes it to be indented more than it should be. This results in an "IndentationError: unexpected indent" error.

To fix this error, you need to make sure that the indentation in your code is consistent and follows the rules of Python's indentation. In general, you should use either spaces or tabs to indent your code, but not both. You should also make sure that each block of code has the same level of indentation. For example:

def my_function():
    print("Hello, world!")
    print("This line has correct indentation")

In this example, we have removed the extra space before the second print statement to ensure that the indentation is consistent. This fixes the "IndentationError: unexpected indent" error.
